Fusion in the inertial electrostatic confinement (IEC) device is taking place via various kinds of collisions like beam-beam, beam-background gas, and beam-target on the electrode’s surfaces. The present work focuses on studying the influence of the electrode material on the neutron yield from the IEC device. Two cathodes made from stainless steel (SS) and titanium (Ti) in the buckyball shape, with 4 cm diameters, were used to perform the study. Experimental setup, conditions, and overview of the results will be presented and discussed in the meeting.
