TUPSA051	Form-factor Determination of an Arbitrary Bunch Sequence for the Coherent Radiation Calculation	radiation, factory, electron, target	322
	D.A. Shkitov, A.E. Harisova TPU, Tomsk, Russia
	It is well known that the coherent effect occur when charged particles in a bunch radiate in phase. This is accompanied by a quadratic increase in the radiation intensity and significantly influences the radiation spectrum. The coherent radiation is characterized by a form factor, which is the coefficient mainly depending on the ratio of bunch dimensions to the observed radiation wave length. The form factors will be different for the synchrotron and transition radiation because of their different nature of radiation. Now electron accelerators that produced beams with a sub-picosecond bunch length and a picosecond distance between them already exist. Through the appearance of interference between radiation from such a sequence of bunches, the total intensity is no longer equal to the sum of radiation from each bunches. For this reason, it is essential to determine the form factor of an arbitrary electron bunch sequence. Herein the uniform bunch distribution will be the special case. In this report we describe an approach to obtaining the form factor of the arbitrary bunch sequence.

THPSC049	Dielectric Chart as a Tool for Diagnosis of Dielectric Materials	dipole, impedance, operation, polarization	641
	V.A. Klemeshev, A.G. Karpov St. Petersburg State University, St. Petersburg, Russia
	One of the most informative diagnostic methods dielectric materials is the analysis of the complex permittivity depending on the frequency of the electric field. Dielectric chart is the dependence of the imaginary part of the complex permittivity of its real part. Thus, difference between the real dielectric chart from the reference or change it during the operation can be a means of diagnostics of dielectric materials. Dielectric chart in the classical theory of Debye is a semicircle with its center lying on the real axis. For solid dielectric the dielectric chart deviation from the semicircle can be quite large, but it still remains a circular arc. This deviation is characterized by parameter a (in the case of the Debye a=0). To clarify the physical meaning of the deviations of the experimental data on the Debye theory, expressed in the value of a, several possible causes have been considered: the effect hindered reorientation of dipoles, the effect of the non-sphericity of the molecules, the complex nature of viscosity. However, the main cause of deviations, in our opinion, is the availability of the distribution of relaxation times around a central relaxation time, in particular, due to defects in the sample. Gaussian distribution width increases rapidly with increasing a. In this paper we propose an algorithm for calculating a, allowing you to quickly determine the condition of the sample on a single parameter. Karpov A.G., Egorov N.V.

THPSC050	Possibilities of Diffraction Radiation Non-Destructive Diagnostics for Non- and Moderately Relativistic Beams	radiation, proton, target, simulation	644
	D.A. Shkitov, A. Potylitsyn TPU, Tomsk, Russia
	Funding: The work was partially supported by the RFBR grant No 15-52-50028. In order to design and construct new modern accelerators with high brightness beams, the development new non-destructive diagnostic tools for accelerated beams is required. Diffraction radiation (DR) is generated by charged particles moving in the vicinity of the conductive target. The DR technique is used successfully for non-destructive diagnostics for ultrarelativistic beams,. For non-relativistic and moderately relativistic charged particles beams (g ~ a few tens or less, g is the Lorentz factor) non-destructive DR diagnostics can be applied also if a beam intensity is high enough due to coherent effect. Intensity of coherent radiation is proportional to the squared bunch population. In this report estimations of non-destructive bunch diagnostics possibility based on DR for the beam parameters of a few machines are presented. Those estimations were performed for electron machine: PITZ project and laser wakefield accelerator, and moreover for ESS proton linear accelerator**. First evaluation of whole wavelength range DR from 4-mm-slit target gave about 56 mJ from one macro-pulse of ESS accelerator. Amplification of DR spectral-angular intensity due to coherent effect will be in N = 10⁸ times than incoherent radiation from the same beam, where N is the bunch population. P.

	Yu. A. Rogovsky, E.A. Bekhtenev, M.I. Bryzgunov, O.I. Meshkov BINP SB RAS, Novosibirsk, Russia O. Chorniy GSI, Darmstadt, Germany
	The Collector Ring (CR) is a dedicated storage ring in the FAIR project, where the main emphasis is laid on the effective stochastic precooling of intense secondary beams of stable ions, rare isotopes or antiprotons. A complex operation scheme with several types of operational cycles with beams in CR starting from injection, RF gymnastics, stochastic cooling then, and finishing to extraction is foreseen. Beam parameters changes significantly during the cycles. This demands an exceptional high dynamic range for the beam instrumentation. Non-destructive methods are mandatory for high currents as well as for the low current secondary beams due to the low repetition rate. Precise measurements of all beam parameters and automatic steering with short response time are required due to the necessary exploitation of the full ring acceptances. An overview of the challenges and solutions for various diagnostic installations will be given.

THPSC070	Measurement of the Proton Beam Profile via an Activation Method of Diagnostics	proton, target, neutron, experiment	698
	E.O. Sokolova Budker INP & NSU, Novosibirsk, Russia D.A. Kasatov, Ya.A. Kolesnikov, I.M. Shchudlo, S.Yu. Taskaev BINP SB RAS, Novosibirsk, Russia
	Funding: The study was supported by grants from the Russian Science Foundation (Project no. 14-32-00006) and the Budker Institute of Nuclear Physics and the Novosibirsk State University. In The Budker Institute of Nuclear Physics the accelerator-based source of epithermal neutrons was invented and now operates to be used in the boron neutron capture therapy. Neutrons on the facility are generated during the threshold reaction 7Li(p, n)7Be which occurs when the proton beam is thrown on the lithium target. To control the neutron output it is necessary to monitor the parameters of the accelerated proton beam. The spatial distribution of the accelerated proton beam was measured exactly on the lithium target. Due to the interaction of protons and lithium there is an accumulation of a radioactive isotope of beryllium takes place. After experiments about neutrons generation it seems possible to track an area of beryllium storage and then restore the proton beam profile. The monitoring of gamma-quants with the energy of 0,477 MeV arising during the beryllium decay was carried out via the gamma-spectrometric complex. The main part of this complex is NaI-scintillation detector, which was pre-calibrated with energy. As a result of such kind of diagnostic the profile of the beam, its shape and characteristic size were determined and the results are depicted in this paper. Afterwards it could be used for an estimation of the total neutrons flux, its quantity, also to assess the target state and restore the proton beam profile.

	Funding: The study was supported by the grants from the Russian Science Foundation (Project No.14-32-00006), Budker Nuclear Institute and Novosibirsk State University. There is the accelerator-tandem at the Nuclear physics institute in Novosibirsk which is suitable for malignancies treatment such as glioblastoma and melanoma using BNCT methods. There are different gamma spectrometry diagnostics which apply under this project. One of these is used to determine the parameters of the neutron beam. The method is to irradiate a set of activation foils with neutrons. Then measure the gamma-spectrum of foils using gamma detector. Based on these data it can be calculated the activity of foil, as well as the amount and the energy of neutrons. For data processing of these diagnostics there was developed a software which is used for convenient display of gamma-spectrometer data and the activity of the foil. Software allows setting a canal calibration and the sensitivity calibration which is needed to calculate the foil activity.

It is well known that the coherent effect occur when charged particles in a bunch radiate in phase. This is accompanied by a quadratic increase in the radiation intensity and significantly influences the radiation spectrum. The coherent radiation is characterized by a form factor, which is the coefficient mainly depending on the ratio of bunch dimensions to the observed radiation wave length. The form factors will be different for the synchrotron and transition radiation because of their different nature of radiation. Now electron accelerators that produced beams with a sub-picosecond bunch length and a picosecond distance between them already exist. Through the appearance of interference between radiation from such a sequence of bunches, the total intensity is no longer equal to the sum of radiation from each bunches. For this reason, it is essential to determine the form factor of an arbitrary electron bunch sequence. Herein the uniform bunch distribution will be the special case. In this report we describe an approach to obtaining the form factor of the arbitrary bunch sequence.

At the present time at ITEP there is a possibility to investigate the biological mechanisms of the low energy protons on living systems on linear accelerator I-2. The unique high current linear accelerator allows to obtain 20 MeV intense proton beams. They could be used for the radiobiological research in a wide range of absorbed doses and for different cell types. Currently some preliminary experiments were made to specify diagnostic equipment required for further investigations. This work presents the main results on the proton beam parameters measurements such as beam current, beam cross section dimension as well as the measurements of the absorbed dose and depth dose distribution using different types of detectors.

One of the most informative diagnostic methods dielectric materials is the analysis of the complex permittivity depending on the frequency of the electric field*. Dielectric chart is the dependence of the imaginary part of the complex permittivity of its real part. Thus, difference between the real dielectric chart from the reference or change it during the operation can be a means of diagnostics of dielectric materials. Dielectric chart in the classical theory of Debye is a semicircle with its center lying on the real axis. For solid dielectric the dielectric chart deviation from the semicircle can be quite large, but it still remains a circular arc. This deviation is characterized by parameter a (in the case of the Debye a=0). To clarify the physical meaning of the deviations of the experimental data on the Debye theory, expressed in the value of a, several possible causes have been considered: the effect hindered reorientation of dipoles, the effect of the non-sphericity of the molecules, the complex nature of viscosity. However, the main cause of deviations, in our opinion, is the availability of the distribution of relaxation times around a central relaxation time, in particular, due to defects in the sample. Gaussian distribution width increases rapidly with increasing a. In this paper we propose an algorithm for calculating a, allowing you to quickly determine the condition of the sample on a single parameter.

Funding: The work was partially supported by the RFBR grant No 15-52-50028.
In order to design and construct new modern accelerators with high brightness beams, the development new non-destructive diagnostic tools for accelerated beams is required. Diffraction radiation (DR) is generated by charged particles moving in the vicinity of the conductive target. The DR technique is used successfully for non-destructive diagnostics for ultrarelativistic beams*,**. For non-relativistic and moderately relativistic charged particles beams (g ~ a few tens or less, g is the Lorentz factor) non-destructive DR diagnostics can be applied also if a beam intensity is high enough due to coherent effect. Intensity of coherent radiation is proportional to the squared bunch population. In this report estimations of non-destructive bunch diagnostics possibility based on DR for the beam parameters of a few machines are presented. Those estimations were performed for electron machine: PITZ project*** and laser wakefield accelerator****, and moreover for ESS proton linear accelerator*****. First evaluation of whole wavelength range DR from 4-mm-slit target gave about 56 mJ from one macro-pulse of ESS accelerator. Amplification of DR spectral-angular intensity due to coherent effect will be in N = 10⁸ times than incoherent radiation from the same beam, where N is the bunch population.

The Collector Ring (CR) is a dedicated storage ring in the FAIR project, where the main emphasis is laid on the effective stochastic precooling of intense secondary beams of stable ions, rare isotopes or antiprotons. A complex operation scheme with several types of operational cycles with beams in CR starting from injection, RF gymnastics, stochastic cooling then, and finishing to extraction is foreseen. Beam parameters changes significantly during the cycles. This demands an exceptional high dynamic range for the beam instrumentation. Non-destructive methods are mandatory for high currents as well as for the low current secondary beams due to the low repetition rate. Precise measurements of all beam parameters and automatic steering with short response time are required due to the necessary exploitation of the full ring acceptances. An overview of the challenges and solutions for various diagnostic installations will be given.

In The Budker Institute of Nuclear Physics the accelerator-based source of epithermal neutrons was invented and now operates to be used in the boron neutron capture therapy. Neutrons on the facility are generated during the threshold reaction 7Li(p, n)7Be which occurs when the proton beam is thrown on the lithium target. To control the neutron output it is necessary to monitor the parameters of the accelerated proton beam. The spatial distribution of the accelerated proton beam was measured exactly on the lithium target. Due to the interaction of protons and lithium there is an accumulation of a radioactive isotope of beryllium takes place. After experiments about neutrons generation it seems possible to track an area of beryllium storage and then restore the proton beam profile. The monitoring of gamma-quants with the energy of 0,477 MeV arising during the beryllium decay was carried out via the gamma-spectrometric complex. The main part of this complex is NaI-scintillation detector, which was pre-calibrated with energy. As a result of such kind of diagnostic the profile of the beam, its shape and characteristic size were determined and the results are depicted in this paper. Afterwards it could be used for an estimation of the total neutrons flux, its quantity, also to assess the target state and restore the proton beam profile.

There is the accelerator-tandem at the Nuclear physics institute in Novosibirsk which is suitable for malignancies treatment such as glioblastoma and melanoma using BNCT methods. There are different gamma spectrometry diagnostics which apply under this project. One of these is used to determine the parameters of the neutron beam. The method is to irradiate a set of activation foils with neutrons. Then measure the gamma-spectrum of foils using gamma detector. Based on these data it can be calculated the activity of foil, as well as the amount and the energy of neutrons. For data processing of these diagnostics there was developed a software which is used for convenient display of gamma-spectrometer data and the activity of the foil. Software allows setting a canal calibration and the sensitivity calibration which is needed to calculate the foil activity.
