Modeling the electron beam from the accelerator LIA-10 on the multiprocessor computer system

The mathematical model of the electron beam's propagation in the experimental volume of the linear inductive accelerator LIA-10 is considered. The main equations and numerical algorithms of the model are briefly described. The results of electron's concentration and self-consistent electromagnetic field calculations are represented. The development of the betatron fluctuation and ultrarelativistic behavior of the electromagnetic radiation's polar pattern are revealed. The comparison of fluctuation parameter with theoretical estimation is cited. The results of simulating the parameters of the beam with experimentally obtained initial angular distribution on the entrance of the accelerating path are represented. The simulation of the magnetic field of the last accelerator's solenoid is calculated. The results of modeling the parallel beam propagation in such a magnetic field are considered. The coincidence of results was detected. So, angular distribution can be caused by the external magnetic field. The model discussed is the internal problem, which appears during calculative domain's decomposition with the help of difference potentials method, when propagation of the beam in the unbounded atmosphere is considered.
