EMITTANCE MEASUREMENTS AT THE STRASBOURG TR24 CYCLOTRON FOR THE ADDITION OF A 65 MeV LINAC BOOSTER

Abstract The long term plans of IPHC foresee the installation of a linac that will boost the energy of the protons of the Strasbourg TR24 cyclotron from 24 MeV to 65 MeV. A Cell Coupled Linac, designed by the TERA Foundation, could be used for this purpose. To compute the transverse acceptances of the linac, the horizontal and vertical emittances of the extracted proton beam need to be measured. The secondary emission detector BISE (Beam Imaging with Secondary Electrons) built by TERA and under development at the Bern 18 MeV IBA cyclotron will be used in Strasbourg for the final measurements. The results of the preliminary measurements of the transverse beam profiles are reported together with the development of BISE, the description of the linac structure and the calculation of the expected output current based on the dynamics of the accelerated proton beam
