Abstract

Fast-response detectors based on natural diamond, which has a long charge-carrier lifetime, have been developed and manufactured for performing time-of-flight measurements of the parameters of plasma and other pulsed sources of ultrasoft X-ray and neutron radiations. Detectors of two types—volumetric detectors for detecting neutrons and X rays with quantum energies of >1 keV and surface detectors for detecting ultrasoft X rays with quantum energies of 200–1000 eV—have been manufactured. Their response time is 1–2 ns (the FWHM duration of a current response). The sensitivity of the volumetric detectors to neutrons with an energy of 14 MeV is at a level of 10–18 C cm2/neutron. The sensitivity of the surface detectors to X rays with an energy of 580 eV is above 5 mA/W.
