Abstract:

An electron lens for space charge compensation is being designed using the CST Studio Suite. The electron lens is a device about 8 meters long, consisting of multiple solenoids and two toroid magnets. In addition, it is equipped with a high current electron gun and a beam collector at the end. The physics goal of this work is to apply the electron lens for compensating ion beam space charge in the synchrotron - SIS18 which is part of the FAIR accelerator complex at GSI.

Charged particle dynamics studies are carried out using the CST particle tracking program. An 30 keV, 11 A electron beam is guided by the magnetic fields (Bz=0.6 T) of the electron lens set-up taking the beams space charge into account. In order to estimate secondary electron emission from the electron lens collector and to optimize the position of the repeller electrodes before the collector, the Furman model which is implemented in CST is used. In this contribution we would like to present the results and discuss the issues we have encountered during the design simulation process.
