Description
Since the 90s the ion beam irradiation experiments are under development at the heavy ion RFQ HIP-1 (Heavy ion Prototype) in the Institute for Theoretical and Experimental Physics named by A.I. Alikhanov of National Research Centre «Kurchatov Institute»; ("Kurchatov institute" - ITEP). The linac provides accelerated beams of $\text{Cu}^2+$, $\text{Fe}^2+$ ions with current up to 6 mA and energy 101 keV/n [1]. Now HIP-1 is used for simulation experiments for reactor material radiation-resistance inestigation by heavy ion beams. Investigated samples are irradiated by beams of metal ions and gas up to fluences 1016. The grid beam extraction system the MEVVA ion source [2] is used now. To increase the life time of extraction system as well as the matching of beam from ion source to the RFQ the accel-decel one hole extraction system is under development. This paper presents results of new extraction system simulation. Also it describes experimental approbation of new extraction system.
