Abstract: | Faraday cup (FC) is a beamline diagnostic which is used to measure the total charge of pulsed beams. The reliable operation of an FC depends on its ability to recapture the ejected electrons when energetic particles strike with interior cup(IC) of an FC. In this paper COMSOL multi-physics software is used to investigate the performance of two new proposed FCs. The FC with A = 40 mm and B = 98 mm had better efficiency in contrast with traditional FC geometries. |
