A vacuum photoemission detector designed for plasma tornography in X rays on the ITER facility is described. Such detectors allow X rays to be detected in the presence of intense neutron and gamma-photon fluxes. The results of tests of a prototype of this detector on a Co-60 source of gamma rays, its calibration using radiation from an X-ray tube, and tests of its serviceability on the T-10 facility are presented. The values of the valid signal and the signal-to-noise ratio are assessed for the parameters of the ITER facility. Selecting the number of detectors and their arrangement on the ITER facility to ensure the required spatial resolution of the diagnostics is considered.</p
