	Since 2007 TRIUMF started development of eLINAC which is a 50 MeV 10 mA CW electron superconducting linear accelerator to be used as a driver to produce radioactive ion beams through photofission. The accelerator is based on five 1.3 GHz TTF/ILC elliptical bulk Nb cavities technology to be mounted in three cryomodules; an injector cryomodule with one cavity and two accelerating modules with two cavities each. The ISAC-II project superconducting heavy ion linear accelerator was successfully completed in 2010 and we now have in operation 40 superconducting bulk Nb QWR cavities assembled in eight cryomodules. Results and plans of the SCRF program and experience of ISAC-II operation at TRIUMF will be discussed.

FRACH05	Prospects for Introduction of Home-Made Equipment for Radionuclide Diagnostics	diagnostics, cyclotron, photon, positron	197
	A.P. Strokach, O.G. Filatov, A.V. Stepanov, M.F. Vorogushin NIIEFA, St. Petersburg, Russia
	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.

TUPPB035	The Kicker Parameters Estimation for Longitudinal Instability Damping of the Beam at SR Storage Ring "Siberia-2"	kicker, cavity, synchrotron, storage-ring	394

	RF system of the Kurchatov Institute Synchrotron Radiation storage ring "Siberia-2" consists of three cavities. Each of them has two HOMs tuners. Due to the shunt impedance and quality factor of HOMs are high, the beam-cavity interaction leads to the instability and the beam loss as the result. We have to develop a longitudinal feedback system based on the kicker, to cure the longitudinal instabilities. In the article the investigations of the field spectra of the cavities at the beam energy 450 MeV and 2,5 GeV, excited by the beam and the generator, are presented. According to the measurements of the field spectra of the cavities, the most strong HOMs were found. Main parameters of the kicker such as a frequency, a shunt impedance, a quality factor and a power, were calculated.
