TUPSA011	Matching the Proton Beam by Means of Independently Phased Bunchers in CYCLINAC Concept	proton, linac, simulation, ion	234
	V.S. Dyubkov, S.M. Polozov, K.E. Prianishnikov MEPhI, Moscow, Russia S.M. Polozov ITEP, Moscow, Russia
	Nowadays a hadron therapy is one of the modern methods of a cancer treatment. For that purpose it is required that a proton beam, accelerated up to 250 MeV, penetrates on a depth about of 30 cm. It is known that linac, cyclotron and synchrotron can be used as a sources of proton/ion beams. The main linac advantages are a high beam quality and a possibility of beam energy variation but, on the other hand, initial low-energy part of a linac is markedly expensive. Production of mentioned beams is possible on the base of a concept called CYCLINAC, when a commercial cyclotron is used as an injector, in which protons are accelerated up to 20-30 MeV, for main linac. Matching the beam from a cyclotron with a linac input is the main problem of this concept. It is caused by difference of operating frequencies of cyclotron and linear accelerator as well as a high phase size of a bunch from the cyclotron. It is proposed to use the system of independently phased bunchers for beam matching. Solenoids are proposed to use for a limitation of transverse emittance growth. The BEAMDULAC-CYCLINAC program is developed for simulation of the self-consistent dynamics of proton beams in a matching channel. Results of beam dynamics simulation for CYCLINAC will be presented and discussed.

	The production of metal ion beams by electron cyclotron resonance (ECR) ion sources using the MIVOC (Metal Ions from Volatile Compounds) method is described. The method is based on the use of metal compounds which have high vapor pressure at room temperature, e.g., C2B10H12, Fe(C5H5)2, etc. Intense ion beams of B and Fe were produced using this method at the FLNR JINR cyclotrons. Experiments on the production of cobalt, chromium, vanadium, germanium, and hafnium ion beams were performed at the test bench of ECR ion sources. Main efforts were put into production and acceleration of 50Ti ion beams at the U-400 cyclotron. The experiments on the production of Ti ion beams were performed at the test bench using natural and enriched compounds of titanium (CH3)5C5Ti(CH3)3. All these efforts allowed the production of accelerated titanium and chromium ion beams at the U-400 cyclotron.

	V.L. Smirnov, S.B. Vorozhtsov JINR, Dubna, Moscow Region, Russia
	An accelerating complex for hadron therapy is proposed. Facility consists of two superconducting cyclotrons and is aimed to produce beams of 12C⁶⁺ ions with energy of 400 MeV/nucleon. Accelerator-injector is a compact 70 MeV/nucleon cyclotron. Main machine is separated sector cyclotron consisting of six magnets. Basic features of the main cyclotron are high magnetic field, compact size, and feasible design of a magnetic system. The advantages of the dual cyclotron design are typical of cyclotron-based solutions. The first design studies of the sector magnet of the main cyclotron show that the beam dynamics is acceptable with the obtained magnetic field. Due to its relatively compact size (outer diameter of 12 m) the complex can be an alternative to synchrotrons. Design study of the main cyclotron is described here.

	S. Korenev, R. Dishman, A. Martin Yebra Siemens Medical Solutions Molecular Imaging, Knoxville, TN, USA R.L. Fink, I. Pavlovsky ANI, Austin, USA N.D. Meshcheryakov, I.B. Smirnov Siemens Healthcare, Moscow, Russia
	This paper presents the results of an experimental study for the use of graphene foils as an extractor (stripper) foil in the 11-MeV Siemens Eclipse Cyclotron. The main advantage of graphene foils compared with carbon and graphite foils is its very high thermal conductivity. The graphene also has significant mechanical strength for atomically thin carbon layers. The life time of these foils is more than 18,000 mkA*H. The graphene foils showed a significant increase in the transmission factor (the ratio of the beam current on the stripper foil to the current on the target), which was approximately 90%. The technology in fabricating these graphene foils is shown. The pros and cons of using the graphene material as a stripper foil in cyclotrons are analyzed.

JINR has the unique experience in cancer treatment with proton beam during about 50 years. In 2005 the collaboration with IBA (Belgium) was established. During these years the technical design of the first carbon superconducting cyclotron C400 was successfully created, the construction of serial proton cyclotron C230 was significantly improved and the fist modernized cyclotron C235 was assembled, debugged and put in the test operation in Dubna in 2013. This C235 will be used soon in the first Russian medical center with proton therapy in Dimitrovgrad. In 2015 the joint project with ASIPP (Hefei, China) on design and construction of superconducting proton cyclotron SC200 was started. Two samples of SC200 should be created according to the Collaboration Agreement between JINR and ASIPP. One will be used for proton therapy in Hefei and the second one should be used to replace the synchrocyclotron Phasotron in investigations on proton therapy at JINR.

H-minus cyclotron has the advantage that high intensity internal beam can be extracted from the acceleration chamber with practically 100% efficiency by transformation H-minus ions into H-plus ion by using thin foil. The extraction system is consists from the probe with stripping foil, extraction window in the vacuum chamber and two correct magnets to match the extracted beam with beam transport line. The beam optics calculations in the measured magnetic field make it possible to find optimal relative position of the extraction system elements as well the parameters of the extracted beam with energy 40 - 80 MeV. At present time the beam is extracted from the chamber with efficiency 100 % and there is good agreement with the optic calculations.

Nowadays a hadron therapy is one of the modern methods of a cancer treatment. For that purpose it is required that a proton beam, accelerated up to 250 MeV, penetrates on a depth about of 30 cm. It is known that linac, cyclotron and synchrotron can be used as a sources of proton/ion beams. The main linac advantages are a high beam quality and a possibility of beam energy variation but, on the other hand, initial low-energy part of a linac is markedly expensive. Production of mentioned beams is possible on the base of a concept called CYCLINAC, when a commercial cyclotron is used as an injector, in which protons are accelerated up to 20-30 MeV, for main linac. Matching the beam from a cyclotron with a linac input is the main problem of this concept. It is caused by difference of operating frequencies of cyclotron and linear accelerator as well as a high phase size of a bunch from the cyclotron. It is proposed to use the system of independently phased bunchers for beam matching. Solenoids are proposed to use for a limitation of transverse emittance growth. The BEAMDULAC-CYCLINAC program is developed for simulation of the self-consistent dynamics of proton beams in a matching channel. Results of beam dynamics simulation for CYCLINAC will be presented and discussed.

The production of metal ion beams by electron cyclotron resonance (ECR) ion sources using the MIVOC (Metal Ions from Volatile Compounds) method is described. The method is based on the use of metal compounds which have high vapor pressure at room temperature, e.g., C2B10H12, Fe(C5H5)2, etc. Intense ion beams of B and Fe were produced using this method at the FLNR JINR cyclotrons. Experiments on the production of cobalt, chromium, vanadium, germanium, and hafnium ion beams were performed at the test bench of ECR ion sources. Main efforts were put into production and acceleration of 50Ti ion beams at the U-400 cyclotron. The experiments on the production of Ti ion beams were performed at the test bench using natural and enriched compounds of titanium (CH3)5C5Ti(CH3)3. All these efforts allowed the production of accelerated titanium and chromium ion beams at the U-400 cyclotron.

Since 1997, different variants of bunching systems have been used at the axial injections of FLNR cyclotrons to increase ions capture into acceleration efficiency. Combination of two single gap Sine and Line bunchers are used at the axial injections of U400 and DC110 cyclotrons. Since 2015, a single gap double RF harmonic buncher has been installed into the upper part of the U400M injection in addition to the lower sine buncher, the experimental results will be presented. For the HV axial injection of the new DC280 cyclotron, two variants of polyharmonic bunchers will be used: a multigap buncher and a single gap one.

An accelerating complex for hadron therapy is proposed. Facility consists of two superconducting cyclotrons and is aimed to produce beams of 12C⁶⁺ ions with energy of 400 MeV/nucleon. Accelerator-injector is a compact 70 MeV/nucleon cyclotron. Main machine is separated sector cyclotron consisting of six magnets. Basic features of the main cyclotron are high magnetic field, compact size, and feasible design of a magnetic system. The advantages of the dual cyclotron design are typical of cyclotron-based solutions. The first design studies of the sector magnet of the main cyclotron show that the beam dynamics is acceptable with the obtained magnetic field. Due to its relatively compact size (outer diameter of 12 m) the complex can be an alternative to synchrotrons. Design study of the main cyclotron is described here.

This paper presents the results of an experimental study for the use of graphene foils as an extractor (stripper) foil in the 11-MeV Siemens Eclipse Cyclotron. The main advantage of graphene foils compared with carbon and graphite foils is its very high thermal conductivity. The graphene also has significant mechanical strength for atomically thin carbon layers. The life time of these foils is more than 18,000 mkA*H. The graphene foils showed a significant increase in the transmission factor (the ratio of the beam current on the stripper foil to the current on the target), which was approximately 90%. The technology in fabricating these graphene foils is shown. The pros and cons of using the graphene material as a stripper foil in cyclotrons are analyzed.
