A present status of IECF based linear neutron source in CPP-IPR

In recent years Inertial Electrostatic Confinement Fusion (IECF) device draws a considerable attention because of its application in neutron activation analysis, land mind detection, plasma space propulsion etc. It is a relatively compact device having the advantage of confining ions in converging electrostatic fields for fusion purposes. While designing the grid structure of IECF device we simulated the electric potential distributions and ion trajectories in it using SIMION 8.0 code. The results predicted ion recirculations for different grid transparencies of inner electrode and a better fusion is expected with optimum transparency in the range of 84%-92%. Monte-Carlo N-particle simulation (MCNP) for estimating the neutron radiation mapping for our IECF experiment was also done. We have found out that a local shield of 35cm thick HDPE around IECF device seen to be sufficient for keeping the neutron and gamma dose rate levels at human occupied places far below the regulatory limit of 1μSv/hr (single particle) and 10μSv/hr (both particle). Details of the results will be presented in the paper
