TUPSA024	On Stabilization of Systems of Linear Equations with Linear Increasing Time Delay by Observation	controls, feedback, acceleration, damping	261
	O.N. Chizhova, A.P. Zhabko Saint Petersburg State University, Saint Petersburg, Russia
	Differential-difference equations with time delay are often used in mathematical models describing the dynamics of beams of the charged particles. For example linear equation of the second order with a constant time delay describes in the smoothed approach dynamics of a beam of the charged particles in synchrotrons with a feedback system. However the time delay cannot always be considered constant. The time proportional delay can occur at acceleration of beams of the charged particles in the cyclotron. It should be noted that such time delay is unbounded and well known approaches are not applicable for stability analysis such systems. The stabilizing control for the system of linear equations could be constructed by the information on a state vector of the system. Sometimes the state vector is unknown but we know some linear combinations of its components. Then there is a problem on construction of the stabilizing control with incomplete information. In this paper we investigate a possibility of stabilization of system of linear equations with time proportional delay by the linear observation. Using the sufficient conditions of asymptotic stability of system of linear equations with linear increasing delay we obtain some conditions of existence of the asymptotic evaluation system of the original system. Then we use the asymptotic evaluation system for the construction of the stabilizing control and derive the sufficient conditions for the existence of such control.

	A.Yu. Antonov St. Petersburg State University, St. Petersburg, Russia M.I. Varajun LETI, Saint-Petersburg, Russia
	The problems of the trajectories constructing for field electrons and emission images simulation are considered. As an approximation of the emitter shape an explicitly and implicitly defined surfaces are selected. Hyperboloidal, ellipsoidal and paraboloidal models are studied. Also an equipotential surface of the charged sphere-on-orthogonal-cone system is used. A simple solution of the field distribution problem is allowed to formulate the Cauchy problem for the motion equations. The shape of the anode (the projector microscope screen) can be selected in any desired form. Achieving a screen by electrons is performed with dense output technique in numerical approach to the solution. The distribution of the work function on the cathode surface is obtained. The trajectories for the projection of the field emission activity as the image are used.

	Symmetry properties of 6D and 4D one-turn symplectic transport matrices were studied. A new parameterization was proposed for 6D matrix, which is an extension of the Lebedev-Bogacz parameterization for 4D case. The parameterization is fully symmetric relative to radial, vertical and longitudinal motion. It can be useful for lattices with strong coupling between all degrees of freedom.

	Funding: The reported study was funded by RFBR according to the research project No. 16-32-00335 mol_a. Coherent instabilities of the bunched beam are one of the reasons that limit a total beam current in the storage rings. Although there are solutions of this problem, the estimation and reduction of wake-fields influence on the longitudinal beam dynamics remain important things. In the article we return to the subject of coherent instabilities of the unevenly-filled bunches in the storage rings.

	O.I. Drivotin, D.A. Ovsyannikov St. Petersburg State University, St. Petersburg, Russia
	The present report is concerned with the problem of particle phase space distributions for a charged particle beam. A new approach is presented. It provides the possibility to specify various coordinates in the phase space. The main attention has been focused on the case where motion integrals are taken as phase coordinates. Using such coordinates, one can obtain a lot of self-consistent distributions. Some distributions for a breathing beam are considered as examples: generalized Brillouin flow, generalized KV distribution, and others. Besides, this approach allows simple graphical representation of various self-consistent distributions.

	In the framework of the HL-LHC project, the vacuum performance of new surface material needs to be studied. In particular, a-C coating is proposed as an anti-multipactor surface in the HL-LHC Inner Triplets. Since the protons in the HL-LHC Inner Triplets will generate synchrotron radiation (SR) with ~ 10 eV critical energy and ~ 10¹⁶ ph/m/s flux, it is therefore of great importance to study the impact of such photons on a-C coating held at room and cryogenic temperature and compare the results against present LHC material. This paper describes construction and parameters of experimental set-up based on new Synchrotron Radiation beamline from booster synchrotron BEP at BINP. The experimental program releasing in collaboration between CERN and BINP for performing measurements of photon stimulated gas desorption, photon distribution and photo-electron emission provoked by synchrotron radiation are presented

	The paper presents studies of the longitudinal broadband impedance of VEPP-4M and measurements of its bunch energy spread at different energies in range of 1.45 - 3.5 GeV. In order to measure the longitudinal bunch size at different currents we used PS-1/S1 streak camera with picosecond temporal resolution. Considering that influence of collective effects is negligible at low currents we determined bunch energy spread from its length at low currents. Collected bunch length data demonstrate microwave instability thresholds and potential well distortion lengthening. Potential well distortion was studied at 3 GeV and 3.5 GeV. Measured potential well distortion lengthening was used to estimate a value of the reactive part of the longitudinal impedance. Observed microwave instability thresholds was used to measure the value of broadband impedance. Measured value of the VEPP-4M is 7.9 ± 1.5 Ohm.
