N2 - A PIG Ion source provides H-ions for the 10 MeV cyclotron, which is designed and being manufactured by Amirkabir University of Technology. Plasma created in the anode contains the desired ions. Discharge for producing plasma consists of the both ion current from plasma towards the cathode and the secondary electron current from the cathode to the plasma. Secondary electron emission is the result of ion collision on the surface of the cathode. Heat generated by these collisions is considerably high, so a cooling system for ion source is crucial. In this paper heat transfer study of the ion source, temperature distribution and deformation of different parts simulated using ANSYS CFX. Also the thermionic emission of the electrons from cathode in the calculated temperatures by ANSYS simulated Using CST STUDIO. Results showed the maximum temperature of the cathodes are 1992 K, which is far away from the cathode melting point. The thermionic current in 1992 K of cathode simulated and the results showed an electron current of 0.00706 A at 500 V which is negligible in comparison to the discharge current of 1.10352 A. Maximum deformation were about 0.2 mm in cathode edges.
