Description
A Faraday cup (FC) suitable for nA intensive beam has been developed to serve nuclear reaction study using the pelletron at the University of Science, Vietnam National University (HUS). Firstly, the FC operation was tested with proton beam of 1-3.2 MeV energies. The diversion of the scattered beam was checked with and without a natural boron target of 0.2 μm thickness on 1.95 μm aluminium substrate. By varying the value, the optimal repeller voltage was found at -350 V which suppressed the secondary electrons from flying out of the cup to ensure the precision of the measuring current. The obtained results were in agreement with the CST simulation’s. Afterwards, the FC was used in the experiment to measure the cross sections of p+12C scattering with Ep=1-3.2 MeV at the angles of 50, 106, 120, 130 and 160 degrees. Except the data at the angle of 50 degrees is new the data at other angles are compared and in good agreement with the published ones.
