Selection of rotating entrance window and target parameters for a gas-filled separator operating at high intensive heavy ion beams

Abstract

The durability of the targets and entrance window foils of the Dubna gas-filled recoil separator working at high intensive heavy ion beams was considered. The temperature, as a factor determining their durability, was calculated as a function of time in the conditions of their pulsed heating by heavy ion beam, followed by radiative cooling by radiation emitted from their surfaces. The temperatures were calculated for 48Ca heavy ion beam with intensity expected for the DC-280 accelerator. With the temperature calculated as a function of time, optimal parameters of the entrance window and target operation were chosen.
