The beams with these parameters will be used for commercial production of a wide spectrum of isotopes for medicine, proton radiation therapy of eye diseases and superficial oncologic diseases as well as for fundamental and applied researches. Manufacturing and installation of the cyclotron equipment and first section of the system for the beam transport to remote targets have been finished. Physical start-up of the cyclotron has been realized. In future, the C-80 cyclotron is supposed to be used as an injector of the C-230 synchrotron, which serves for additional acceleration of the extracted proton beam to energies of the order of 230 MeV. This will allow the Bragg's peak-based treatment procedures to be applied in the proton therapy of oncologic patients.

FRXOR02	Beam Diagnostic Instrumentation for the NSLS-II Booster	booster, vacuum, controls, radiation	186
	V.V. Smaluk BNL, Upton, Long Island, New York, USA
	For the NSLS-II synchrotron light source, a Booster synchrotron has been designed and produced by Budker Institute of Nuclear Physics. The Booster accelerates an electron beam from 200 MeV up to 3 GeV in both single-bunch and multi-bunch modes with repetition rate of 1 Hz. Accurate measurements of beam parameters are required during every work cycle to provide feed-forward tuning of the Booster. A set of beam diagnostic instruments has been developed for the Booster commissioning and operation. Six fluorescent screens are used for the first-turn beam observation. Electrostatic BPMs with signal processing electronics developed by BNL provide measurements of closed orbit and lattice functions as well as single-pass beam measurements for commissioning. A DC current transformer is used to measure average beam current and lifetime; the filling pattern is monitored by a fast current transformer. Two light-output ports are set up for observation of the beam image. Tune measurement system provides frequent measurements of betatron tunes during the energy ramp. Design and performance of the Booster beam instrumentation are presented; the commissioning plan is also discussed.

	Radionuclide diagnostics that allows most diseases to be diagnosed at an early stage has recently been in the focus of attention. The current concept of radionuclide diagnostics advancement takes into account Russian geographic and demographic features and supports the application of the home-made equipment. As a basis, the concept assumes the establishment of regional diagnostic centers at hospitals in each Russian Federal district. In each such a center, a cyclotron of the CC-18/9 model, modules for radiopharmaceuticals' synthesis, single-photon emission (SPECT) and positron (PET) scanners should be installed. The yield of radiopharmaceuticals' production will satisfy the needs of such a center and of up to 30-35 SPECT-"satellites" located in diagnostic departments at hospitals situated up to 1000 km from the center. In future, on the basis of these diagnostic departments, autonomous PET-centers can be established, each equipped with СС-12 cyclotrons, modules for radiopharmaceuticals' synthesis and with 3-4 PET scanners. Implementation of the Federal Targeted Program on the serial production of cyclotrons and SPECT-scanners will allow the examination of population to be increased within 5-6 years up to 1.0-1.2 million people per year.

	It is well known presently that radionuclides produced with cyclotrons have very good nuclear-physical characteristics for use in medicine and a set of these nuclides is much wider than produced with the reactors. At PNPI a high current cyclotron C-80 with the energy of extracted proton beam of 40-80 MeV and the current up to 200 mkA is under construction. It is planned to start its operation at the end of 2012. One of the main goals of C-80 is production of a wide spectrum of medical radio- nuclides for diagnostics and therapy. At present time a project is worked out for the construction of radioisotope complex RIC-80 (Radio Isotopes at the cyclotron C-80) at the beam of C-80. In the presented submission the project of RIC-80 complex is discussed, which includes four target stations for the production of a wide set of radionuclides for medicine. The peculiarity of the proposed radioisotope facility is the use of the mass-separator with the target-ion source device as one of the target stations for on-line, or semi on-line production of a high purity separated radioisotopes. The possibility of production of different medical radionuclides, including relatively short-lived ones, is discussed as well.

Even if the field of synchronous harmonic is aberration free, the higher space harmonics provide non linear additives in the field distribution, leading to emittance growth during phase space manipulation. Standing wave operation is more RF efficient for short deflectors. The criterion of the field quality estimation and results is of deflecting structure consideration for minimization of non linear additives are presented.

WEPPD040	Precision Thermostatic Control for LUE-200 Accelerator Section	controls, linac, neutron, electron	629
	V.N. Zamriy, A.P. Sumbaev JINR, Dubna, Moscow Region, Russia
	According to the design of the IREN facility the system of thermostatting of LUE-200 linac sections is developed. Rated values of linac beam power depend basically on a microwave power input and stability of the phase. The latter is sustained by means of thermostatic control for the sections subject to the powerful microwave warming-up. Demanded both high accuracy of stabilization and low settling time of temperature for linac modes define development of the control system. The precise system of thermostatic control in which composition the programmable PID-controller and the platinum resistance thermometer with accuracy of 0.1%, and also thyristor regulators of heating power up to 15 kVА has been adapted for modes of the IREN microwave facility. The advanced system allows to control both power of heating and a flow of cooling water. The system supervises and changes over modes of the accelerated warming-up and controllable heating and cooling. Both high accuracy of the thermostat and energy saving at a smooth settling of temperature and at the subsequent long-term thermostabilization are substantially improved. Essential speed-up of a preliminary warming-up of the thermostat also is attained.

WEPPD047	The Optimization of RF Deflector Input Power Coupler	coupling, emittance, electron, simulation	650
	A.Yu. Smirnov, O.A. Adonev, N.P. Sobenin MEPhI, Moscow, Russia A.A. Zavadtsev Nano, Moscow, Russia
	This paper concerns the investigation of different types of input power cell for S-band RF electron deflector. This device serving for slice emittance diagnostics is a disc-loaded waveguide which operates with TE11-like wave in traveling wave regime with 120 deg phase shift per cell. Since this deflector meets the restriction on its length and has to provide high enough deflecting potential to a particle during its flight time it is significant to increase the transversal field strength in coupling cell or to shorten it so that the deflecting potential remains constant. The total structure consists of 14 regular cells and two couplers. As it is now all cells have the same length equal to D=33.34 mm and the field in couplers is lower than that of regular cells. In this paper different length are considered and numerically simulated in order to choose the best one.

	E.S. Belonogaya, S.N. Galyamin, A.V. Tyukhtin Saint-Petersburg State University, Saint-Petersburg, Russia
	Cherenkov radiation is widely used for particle detection. As well, it is prospective for particle bunch diagnostics. Therefore, it is actual to elaborate methods for calculation of the fields of bunches moving in the presence of different dielectric objects. We offer the approximate method based on calculation of the field in unbounded medium and accounting of boundary influence by geometrical optics. First, we consider the problem concerning the field of charge crossing a dielectric plate. This problem has an exact solution. It is used as a "test" problem for estimation of precision of the approximate method. Computation of the field is performed using both methods and the results have a good agreement. Further, we analyze the cases of more complex objects, in particular, a dielectric cone. Note, that the offered method allows to obtain wave fields using neither complex analytical transformations nor laborious numerical calculations.
