	New crystal technique – bent crystal array and veer – type reflector based on straight crystals were used like first stage in collimation system at U-70 accelerator. Efficiency of collimation was enhanced up to 90% in two-stage collimation system which included first crystal stage and long steel absorber like second stage. While in previous one-stage system without crystal only 40% protons hit deeply in absorber. For data taking and analysis of information modified modern beam diagnostic system was applied.

	B. A. Frolov IHEP Protvino, Protvino, Moscow Region
	For the carbon ion injection into the radio frequency quadrupole, a laser ion source and a low energy beam transport system (LEBT) has to deliver 20 mA C+5 ion beam with 80 keV at the entrance of RFQ within normalized emittance of 0.4Pi mm mrad. An extraction system and a low energy transport line should be optimized to reduce the beam emittance as far as possible. The results of computer simulation are presented for extraction and LEBT systems: combinations of a tetrode extraction system and an electrostatic focusing lens consisting of three electrodes with negative voltage of a middle grid electrode.

WEPSB017	Space Charge Simulation Using MADX with Account of Synchrotron Oscillations	lattice, simulation, emittance, space-charge	204
	V. V. Kapin MEPhI, Moscow Y. Alexahin Fermilab, Batavia
	Direct space charge forces can be simulated with the 6D beam dynamics code MADX using a number of 4D BEAMBEAM elements with Gaussian transverse profile for charge density. To take into account effects of synchrotron oscillations on space charge forces, the amplitude of BEAMBEAM elements is modulated according to the distance between a particle and the bunch center assuming Gaussian longitudinal profile. Parameters of every BEAMBEAM element (charge and sizes) are defined by local values of beta-function and dispersion, while they are updated according to the beam intensity and beam emittances at every turn. MADX script accomplishing this method has been written for the lattice of the existing Debuncher ring. The slow extraction at the 3rd order resonance with simultaneously varying the horizontal tune and the sextupole strength is considered as one of the options for Debuncher to be used in the "mu2e" project. Our MADX simulation results are compared with results obtained by V. Nagaslaev (FNAL) using the particle-in-cell ORBIT-code. The evolutions of the phase-spaces and the beam intensity within ten thousands turns have shown a good agreement between the MADX and ORBIT results.

Intensive beam current oscillations with frequency of ~1MHz and up to 70% modulation level (for ion current ~ 100 mA) with plasma expansion cap of different shape were observed. It has been found by direct measurements that these oscillations are formed during plasma transport through the expansion cap.

Results of the 400keV hydrogen ion beam current and emittance measurements are presented.

This cyclotron will be used for radiotherapy with proton, helium and carbon ions. The 12C⁶⁺and 4He²⁺ ions will be accelerated to the energy of 400 MeV/amu, the protons will be extracted at the energy 265 MeV. The C400 construction is started in 2010 in frame of the Arharde project (France).
