内容記述 |
Background plasma behaviour in the low energy transport section of the LIPAc is analysed with 3-dimensional particle-in-cell simulation. The simulation showed some characteristic effect under external field elements in the LEBT: a positive biased chopper absorbed the electron plasma in the surrounding drift region, that is limited by the solenoid lenses, though indicating some electron leakage through the solenoid still be there. Analytically estimated flux of the electron leakages through solenoid is compared to the simulation results. Results of experiments still has a mysterious transient motion of beam pulse shape that is not shown in the simulations, while saturated state is roughly reproduced in it. |
