摘要：
Miniature metal-diamond wire detectors have been fabricated by Hot Filament Chemical Vapor Deposition (HFCVD) method and characterized as x-ray dosimeters in the energy range 50 keV-250 keV. Linearity of the response and the sensitivity as a function of energy have been accurately determined in a range routinely used for x-ray radiotherapy. With a Mo wire substrate, a 10 mu m thick CVD diamond film can reach sensitivities of the order of 4x10(-8) A/Gy/min, more than one order of magnitude larger than for a 6 cm(3) standard ionization chamber.
