A Space Charge Compensation Study of Low Energy Hydrogen Ion Beams

High-power accelerators are being studied for several projects including accelerator driven neutron or neutrino sources. The low energy part of these facilities has to be carefully optimized to match the beam requirements of the higher energy parts. The complexity of high intensity beam dynamics in the low energy line is essentially due to the non-linear space charge effects. The PIC code CARTAGO [1] has been developed in order to simulate the beam transport at low energy including the temporal evolution of the space charge compensation. This paper relates new features of the code. The effects of the longitudinal space charge, the image charge and external magnetic field were included. The results of beam transports using solenoid are discussed. Space charge compensation degrees are given.
