	The project of a nuclear medicine complex based on the isochronous cyclotron of negative hydrogen ions C - 80 is being developed at the National Research Center "Kurchatov Institute" - PNPI. The project provides for the design of a building, the creation of stations for the development of methods for obtaining new popular radionuclides and radiopharmaceuticals based on them. The commercial component is not excluded. The project also provides for the creation of a complex of proton therapy of the eyesight. For these purposes, the modernization of the beam extraction system of the cyclotron C-80 is planned: a project for the simultaneously two beams extraction systems are being developed. The one for the production of isotopes with an intensity up to 100 mkA and an energy of 40-80 MeV and the second - for ophthalmology with an energy of 70 MeV and intensity up to 10 mkA. The paper presents the calculation and layout of the beam transport lines to the target stations, the operation mode of the magnetic elements and beam envelopes. The method of the proton beam formation for ophthalmology and its parameters are described.

TUPSB16	Calculation and Optimization of High-Energy Beam Transfer Lines by the Monte Carlo Method	proton, emittance, ion-source, radiation	262
	D.A. Amerkanov, E.M. Ivanov, G.A. Riabov, V.A. Tonkikh PNPI, Gatchina, Leningrad District, Russia
	The calculation of high-energy beam lines consists of tracing of the proton beam trajectories along the transport channel from the source. The PROTON_MK program code was developed to carry out such calculations using the Monte Carlo method. The beam from the accelerator is introduced in the form of a multivariate Gaussian distribution in x,x’,z,z’,dp/p phase space. In the case when an absorber (absorber, air section, window in the channel, etc.) is installed in the transport channel the beam parameters after the absorber are calculated using the GEANT4. The output file of this code can be used as input for the program. The program allows calculation of any beam parameters - intensity, spatial or phase density, energy distribution, etc. The program includes a block for the optimization of beam parameters presented in a functional form. Random search method with learning for search correction based on analysis of intermediate results (so-called statistical gradient method) is used for obtaining the global maximum of a function of many variables. The program has been tested in calculations of the beam transport lines for IC-80 cyclotron and for the development of the beam line for ophthalmology.

WEPSC10	Optimization of Accelerators Vacuum Structures Pumping	vacuum, rfq, simulation, cavity	361
	S.M. Polozov, A.S. Panishev, V.L. Shatokhin MEPhI, Moscow, Russia
	The pumping features for the complex parts of the accelerator vacuum system are modeled to growth the efficiency of vacuum pumping. The vacuum system of a 7.5 MeV/nucleon proton and light ion (A/Z<3.2) accelerator-injector was considered. The Monte Carlo method is suitable for molecular flow modeling in high vacuum. The Molflow+ program was used for this aim. The pressure distribution simulation over the RFQ, IH resonators chambers volume, connecting vacuum pipes and extended vacuum tracts is carried out. The influence of parameters of individual structural elements changes was investigated to define the vacuum conditions inside the accelerators vacuum chambers. The vacuum system configuration and parameters are selected basing on these results to obtain the required vacuum level.
