| Abstract |
The Italian TOP IMPLART project aims to develop the first proton linear accelerator for cancer radiotherapy. A 150MeV proton LINAC is under construction at the ENEA Frascati research center: currently the machine is composed by a 7MeV injector operating at 425MHz and four 3GHz SCDTL modules producing a proton beam of 35MeV. Operational procedures for irradiation of samples need careful measurements of average beam current, transverse distribution and pulse charge by different monitor types placed along the beam line. The injected current in the high frequency segment of the accelerator is measured by a Fast Current Transformer (FCT) at the entrance of the SCDTL modules and the pulsed current of the accelerated beam is measured by a second FCT, placed in air, at the exit. The output proton beam shape and intensity are measured by an integral ionization chamber, a double (XY) multistrip ionization chamber, a synthetic single crystal diamond detector and a Faraday cup. In this work, the results of these multiple diagnostic tools applied to different operating conditions of the machine are presented.
