MOPCP005	Kharkov Compact Cyclotron CV-28: Present and Future Status	cyclotron, ion, target, proton	54
	Y.T. Petrusenko, D.Y. Barankov, D.O. Irzhevskyi, S.M. Shkyryda NSC/KIPT, Kharkov, Ukraine R. Hölzle FZJ, Jülich, Germany
	Reported are the present and future statuses of the Kharkov Compact Cyclotron CV-28 donated to the National Science Center - Kharkov Institute of Physics & Technology (NSC KIPT) by the Forschungszentrum Jülich (Germany). The cyclotron configuration and special features of new installation at the NSC KIPT are presented. Consideration is given to the problems of promising cyclotron-beam use for investigation and development of materials for fusion reactors and generation-IV nuclear reactors, investigation and production of medical radionuclides, possible applications of a high-energy neutron source based on a deuteron beam and a thick beryllium target.

MOPCP011	25 Years of Continuous Operation of the Seattle Clinical Cyclotron Facility	controls, cyclotron, target, isotope-production	66
	R. Risler, S.P. Banerian, J.G. Douglas, R.C. Emery, I.J. Kalet, G.E. Laramore, D.D. Reid University of Washington Medical Center, Seattle, USA
	The clinical cyclotron facility at the University of Washington Medical Center has now been in continuous operation for over 25 years. It is highly reliable, and its primary use is still for fast neutron therapy, mostly for salivary gland tumors. Neutron therapy accounts for about 85% of the facility use time. In cases where the tumor involves the base of the skull, significant improvements of patient outcome have been achieved by combining the neutron treatment with a gamma knife boost to areas where the neutron dose is limited by adjacent healthy tissue. Production of 211-At and 117m-Sn with alpha particles at 29.0 and 47.3 MeV and currents between 50 and 70 μA have become routine. These isotopes are used in medical applications presently under development. The introduction of a new control system using EPICS (Experimental Physics and Industrial Control System) is progressing systematically. All the user interfaces are up and running, and several accelerator subsystems have been migrated to the new controls. No interruption of therapy or isotope production operation is planned for the conversion to the new control system.

MOPCP022	Present Operational Status of NIRS Cyclotrons (AVF930, HM18)	cyclotron, target, controls, proton	96
	M. Kanazawa, S. Hojo, T. Honma, A. Sugiura, K. Tashiro NIRS, Chiba-shi, Japan T. Kamiya, T. Okada, Y. Takahashi AEC, Chiba, Japan
	Since Japanese government launched a new program of the 'Molecular Imaging Research Program' in 2005, NIRS AVF930 cyclotron has been mainly operated to produce radio-isotopes together with a small cyclotron (HM18) for PET diagnosis. There is also machine operation of AVF930 for physical experiments and tests of radiation damage on electric devices. To carry out the cyclotron operations for these purposes, some improvements have been done in the facility. In this report, we will present recent operational status of NIRS cyclotron facility (AVF930, HM18).

MOPCP081	Design Study of Magnetic Channel at NIRS-AVF930	cyclotron, proton, extraction, simulation	215
	S. Hojo, T. Honma, M. Kanazawa, N. Miyahara, M. Muramatsu, K. Noda, Y. Sakamoto, A. Sugiura, K. Tashiro NIRS, Chiba-shi, Japan T. Kamiya, T. Okada, Y. Takahashi AEC, Chiba, Japan
	In the NIRS (National Institute of Radiological Sciences) AVF930 cyclotron, a current magnetic channel has been used for ten years, and the flowing rate of cooling water at longest coil is gradually decreasing. Therefore, the high energy operation such as 70 MeV proton became difficult recently. As the design specification of this magnetic channel is very severe, the flow velocity of cooling water is very fast. The sectional area of the longest coil is expanded in the new design of magnetic channel. Details of the new design and results of calculated magnetic fields are discussed.
