Advance of CSNS Solid Target

Abstract:

A 100 kW solid target was successfully developed for the CSNS phase one. Tungsten was selected as the CSNS target material and a layer of tantalum with a thickness of only 0.3mm as a protective layer. Eleven target blocks were fixed in parallel in a stainless steel target container with 1.2mm gap between each block. Using a specially designed spreader, the target plug can be easily replaced. The parameters of the target were stable and normal in the course of more than a year of operation, the temperature rise of the target cooling water inlet and outlet increased as the proton beam power increased.
