TUPSA013	The CDS Parameters for Proton Linac with Moderate Heat Loading	linac, coupling, proton, electron	65
	V. V. Paramonov RAS/INR, Moscow
	The Cut Disk Structure (CDS) was originally proposed for high energy linac in L-band or S-band frequency range. CDS combines simultaneously high coupling coefficient, high shunt impedance and small transverse dimensions. For lower particle velocity the structure loses in shunt impedance due to relatively thick partition with internal cooling channels. For moderate heat loading internal cooling is not necessary and partition thickness is limited only by mechanical rigidity. The structure equalizes in shunt impedance with another bi-periodical structures and another CDS advantages come in front. Calculated CDS parameters for proton linac are presented.

	The DLNP JINR activity is aimed at developing two directions in radiation medicine: development of accelerator technique for proton and carbon treatment of tumors and new types of detector systems for spectrometric computed tomography (CT) and combined magnetic resonance tomography (MRT)/positron emission tomography (PET). JINR-IBA realized the development and construction of proton medical cyclotron C235-V3. At present time all basic cyclotron systems were constructed. During 2010 we plan to assemble this cyclotron in JINR and in 2011 perform tests with extracted proton beam. A superconducting isochronous cyclotron C400 has been designed by IBA-JINR collaboration. 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).
