IPC: H01L39/22
Filed: 2000-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a radiation detector whose energy resolution is high and whose sensitive area is large. SOLUTION: In the radiation detector, four normal conductors 3A to 3D which are separated mutually form an NIS junction in such a way that a superconductor 2 as a single body is used in common, and electric connection bodies 5A to 5C are constituted to be electrically connected in a state that their thermal insulation is maintained mutually.
