A new normal-conducting, CW, thermocathode RF gun was developed and tested at Budker Institute of Nuclear Physics recently. Providing average current up to 100 mA, this device will be used to upgrade the injector of Novosibirsk FEL facility. A beam dynamics simulation in RF gun and its beamline was made with space-charge forces being taken into account. Comparison of the simulation results and experimental measurements is presented in this paper.
