Abstract

Abstract: A prototype of tungsten pins beam dump was tested with high power electron beam at the JUDITH 2 facility. A maximum electron beam power of 40 kW was applied on a nominal beam spot area of 4 × 4 cm 2 . This corresponds to the highest achieved beam power density of 1.4 kW/cm 2 . Approximately 16% of the deposited energy was removed by radiation at the highest beam power values, corresponding to estimated surface temperature of ≈ 3100 K. The results of the irradiation test are presented. The further improvements of the prototype are discussed. This result provides an encouraging input for possible design of a full power beam dump for SARAF Phase II.
