BEAM TRANSVERSE PROFILE MONITOR FOR IFMIF-EVEDA ACCELERATOR

In the framework of the IFMIF-EVEDA project, a high deuteron beam intensity (125 mA- 9 MeV) prototype accelerator will be built and tested at Rokkasho (Japan). CEA-Saclay group and Ciemat-Madrid (Spain) are responsible of the beam instrumentation from the ion source to the beam dump. One of the most challenging diagnostic is the Beam Transverse Profile Monitor (BTPM). CEA-Saclay group investigates such a monitor based on residual gas ionization. This monitor uses a high electric field to drive the products (electrons and ions) of ionization to micro-strips. A priori, no primary amplification is required due to the high beam intensity. Nevertheless, in order to study the feasibility, a prototype will be tested in a proton beam
