Design and simulation of 2MV electrostatic accelerator tube

In this paper design and simulation of an optimized accelerator tube is presented for the production of light charged particles up to energy of 2 MeV. Geometry of the accelerator tube electrodes was simulated based on the Van De Graaff accelerator tubes of Atomic Energy Organization by SIMION 7.0, Virtual Device and SIMION Toolkit codes. In accelerator tube, the extracted ion beam from the ion source is accelerated and converged thru the initial electrodes which each of the electrodes potential applied are slightly less than the former. Then, beam energy is increased by resemble acceleration electrodes and is guided to the target through drift tube. In this paper, we study beam dynamic in the simulated accelerator tube and effect of the different electrodes on the beam quality by features of the beam emittance criteria.
