Abstract :
A new version of PARMTEQ with 3D space charge and an approximate image charge treatment has been written and used to simulate several high-current RFQs (radio-frequency quadrupoles). The author explains the calculational method and gives simulation results. It is shown that the 3D space-charge treatment made little difference in the PARMTEQ results. Image charges, on the other hand, caused significant beam loss in some cases. This effect should be taken into account in designing high-brightness, high-current RFQs.<>
