Dynamics of the thermal state of the foil scanned with an electron beam

Abstract

A beam with an average power up to 500 kW is extracted from a vacuum volume of an accelerator through a system of foil-closed windows used alternately. In each window the beam scans a rectangular area 2500 x 40 mm in size. The ANSYS code was used to study temperature fluctuations of the foil and foil-supporting grid heated with the beam
