Description
A comprehensive electromagnetic and beam-dynamics model of the High Brightness Beam Test Facility (HB2TF) electron injector under development at INFN-LASA has been implemented using COMSOL Multiphysics. The model incorporates the DC photocathode gun and the low-energy transport line. Three-dimensional electric and magnetic field distributions were computed and employed for particle tracking within COMSOL, enabling analysis of field effects, mesh resolution impacts, and space-charge contributions. The resulting field maps were exported and imported into ASTRA and RF-Track simulation codes to perform cross-validation of beam dynamics. Comparative studies focus on transverse emittance, bunch length, energy spread, and sensitivity to field map resolution. This work establishes a validated modelling workflow for the HB2TF injector and provides crucial input for its optimisation and future commissioning.
