	In this paper the preliminary design of magnet lattice of the Carbon Ion Therapy Facility with electron cooling is described. The influence of misalignments of magnetic elements on ring parameters and the layout of orbit correction are estimated. The different methods of ion extractions from the synchrotron are considered, i.e., the pellet extraction, recombination extraction and the extraction on the sextupole resonance.
TUOBG02	Study of Beam Dynamics During the Crossing of Resonances in the VEPP-4M Storage Ring	965

	The influence of resonances on the beam dynamics in the storage rings is of a substantial interest for the accelerator physics. For example, a fast crossing of resonances occurs in the damping rings of future linear colliders during the beam damping due to the coherent shift that can result in a loss of particles. We have studied experimentally the crossing of resonances of different power nearby the working point of the VEPP-4M storage ring. The observation of the beam sizes and particle losses has been done with a single-turn time resolution. The comparison with the numerical simulation has been made.

	The nearest experimental program of the VEPP-4M electron-positron collider and the KEDR detector includes a scan of the energy area below J/psi meson to search narrow resonances. The monitoring of beam energy spread is important for that. In this report we discuss the application of several diagnostics for beam energy spread measurement. The data obtained with Compton Back-Scattering (CBS) technique are compared with the value of the spread derived from the betatron motion of the beam. Similar experiments were carried out before. They demonstrated the necessity to improve the algorithm of beam energy spread derivation using CBS technique. New set of experiments was aimed on the examination of the improved algorithm. The measurements by all the methods were done at the same accelerator run, i.e., the different diagnostics are compared directly. The value of the energy spread was determined for a fixed collider energy E= 1855 MeV. The beam energy spread was changed by the wiggler current variation.

	To determine experimentally the particle stable area under the influence of beam-beam effects in the electron-positron collider VEPP-4M we measure the beam lifetime with high accuracy as a function of moving aperture. The measurement is performed by a photodiode installed in the collider diagnostic beam line. The experimental setup and the measurement results are described. Comparison with the tracking simulation is presented.
