New tests of fluorescence beam profilers for the linear IFMIF prototype accelerator (LIPAC) using 9 MeV deuteron beams

Abstract

LIPAc prototype accelerator will be a 9 MeV, 125 mA continuous wave (CW) deuteron accelerator, focused on validating the technology that will be used in the future IFMIF facility. In this high power accelerator (1.125 MW), interceptive profilers are forbidden during the nominal operation. In the quest of non interceptive beam transverse profilers required for LIPAc, two prototypes based on the fluorescence of residual gas have been developed by CIEMAT. New experimental tests using 9 MeV deuterons were performed at CNA using the prototypes. Tests include injection of hydrogen, injection of nitrogen for comparison with previous results and a beam steering experiment. Hence, a brief description of the beam transverse profile prototypes together with a summary of the improved new measurements are presented.
