Abstract

Microwave chemical vapor deposited (CVD) diamond films have been used to fabricate radiation detectors. The polycristalline diamond films have a resistivity of 10¹² Ω.cm and carrier mobility and lifetime of about 280 cm²/V.s and 530 ps. The detector response to laser pulses (λ = 355, 532 and 1064 nm), X-ray flux (15 - 50 keV) and alpha particles (²⁴¹Am, 5.49 MeV) has been investigated. The response speed of the detector is in the 100 ps range. A sensitivity of about 3 × 10^-10 A/V.Gy.s was measured under 50 keV X-ray flux. The detector current response to X-ray flux is almost linear. It is also shown that CVD diamond detectors can be used for alpha particle counting.
