Abstract—The design of a diamond neutral-particle spectrometer (DNPS) is presented. The DNPS is a part of the neutral particle analyzer (NPA) at the International Thermonuclear Experimental Reactor (ITER). The operating modes of the DNPS in the NPA complex, the advantages of the DNPS, and its limitations are described. The DNPS system includes two diamond detectors that differ in sensitivity by a factor of 9. The energy losses in detector contacts are numerically estimated. The test results for the diamond detector are presented.
