Modelling of ionization in a spherical hot cavity source

Warianty tytułu
Języki publikacji
A Monte Carlo method-based model of hot cavity surface ion source with spherically shaped ionizer is presented. A numerical code enables studies of ion source efficiency as function of extraction voltage, geometry of the ionizer and its temperature, the size of extraction aperture and many other factors. A novel configuration of surface ion source is proposed and discussed – the efficiency of the modified ion source could be much higher than that of currently used sources. In order to take advantage of multiprocessor computer or cluster the code has been made parallel. Two different strategies of parallelization are considered. Results of hard and weak scaling tests are presented, showing very good scalability of the code up to 16 CPUs.
