Description
Program package WinSAM has been developed in BINP and is actively used now for calculating of electron-optical systems with space charge dominated beams, such as electron guns, collectors, accelerator systems, etc. The article describes the work aimed at further improvement of the package. The main efforts were aimed at improving and accelerating the calculation of long systems with intense beams. To do this, a module was included in WinSAM that allows calculations using PIC method with series representation of external fields, which allowed to drastically reduce the calculation time while maintaining the required level of accuracy. An example of calculating a long accelerator system is given. In addition, a transition was made to multithreaded computing using the OpenMP standard.
