The neutron production rate (NPR) through fusion reaction on the surface of electrode(s) of an IECF (Inertial Electrostatic Confinement Fusion) device, which is expected to increase at low pressure, has been evaluated with a one dimensional simulation code and an experimental device. In the simulation, the NPR on the cathode and the anode has been evaluated individually as a function of pressure. The simulation results reveal that the NPR on the cathode increases at low pressure and that on the anodes increases at high pressure. In the experiment, titanium coated electrodes have been used in order to rise the adsorbed amount, and the results show same tendency along with the pressure as calculation results. And the maximum value increases 3 times by coating titanium.
