Design of the divertor targets shielding frame of the HELCZA high heat flux experimental complex

This article presents a design of the HELCZA shielding frame for the divertor inner vertical targets irradiation by the electron beam with a power density of 40 MW/m2. The design includes the choice of the geometric shape of the frame, determines the frame heat load and provides thermohydraulic calculations for the frame cooling, including the determination of pressure losses.
