  Electron accelerators are made of different parts and one of the main part of every electron accelerator is its electron gun. In this article a diode electron gun is designed and simulated for a 1MeV parallel feed Cockcroft-Walton accelerator for industrial applications. The pierce configuration is selected for focusing electrode. Simulations are carried out using CST Particle Studio. The gun is thermionic with indirect heating of spherical dispenser cathode that is made from porous tungsten which is impregnated with barium compounds. The gun maximum achievable current is 200 mA at 10 kV and required current in our accelerator is about 100 mA.

  In this article accelerating tubes whit different geometries and different constructions are designed and simulated for a 1 MeV parallel feed Cockcroft-Walton electrostatic industrial accelerator. Simulations are carried out using CST Particle Studio. The accelerating tubes with different focusing electrode and accelerating electrode geometries are designed and simulated and compared with each other. Finally whit respect to the comparisons best geometry is selected. In this tube a 1 MV DC voltage is applied at several stages during the accelerating electrodes. Maximum electron beam current in the tube is 200 mA. In this application accelerating electrodes and focusing electrodes are made of stainless steel and insulators between electrodes are made of Borosilicate glass.

  A control system has been designed for the commissioning of 10 MeV linear accelerator which is under construction in institute for research in fundamental science (IPM). The IPM e-Linac is a traveling wave accelerator consisting of 62 components in five major sections: control and safety, beam injection, radio frequency production and transmission, acceleration tube and target. The existence of a central control system for controlling and monitoring all parts of the machine is necessary. The aim of the system design is to implement a fast and reliable control system which is easy to operate and extensible for future upgrades and improvements. For this purpose, EPICS has been chosen as the main environment due to high performance and distributed structure. In this system, Siemens PLC is used as EPICS IOC and graphical designs will performed by CSS and WinCC. In this study, first we present a brief description of the IPM electron linear accelerator, and then architecture of the control system will be discussed.
