An edge-cooled graphite target for J-PARC Muon Science Facility

At the Muon Science Facility J-PARC, we are investigating whether we can adopt an edge-cooled non-rotating graphite target because of its ease of handling and maintenance, although one promising candidate of the production target for 1 MW proton beam is a rotating graphite target which has been developed at PSI. s paper, we report a promising design of the KEK model of the edge-cooled non-rotating graphite target for 1 MW operation at J-PARC Muon Science Facility, based upon a new idea inserting a Ti buffer layer at the interface between graphite and copper frame, together with the successful fabrication of the proto-type target according to the dedicated design of our request.
