Abstract
Section titled āAbstractāAbstract Diamond with extraordinary properties, such as fast response, and extremely high thermal conductivity, is an ideal choice for the next generation radiation detectors. In this paper, a radiation detector based on a single crystal CVD diamond (3 mm Ć 3 mm Ć 200 Ī¼m) with (100) orientation is proposed to detect Ī± radiation. The detector employs gold films on the diamond as an electrical contact, and the origin-symmetric current-voltage characteristics demonstrated excellent Ohmic contact behavior. At an electric field of 0.4 V/Ī¼m, a current dark value of 4 nA was measured. The detectorās pulse speed was tested using 5.486 MeV 241 Am sources. The time response of the detector to Ī± particles is fast, with a rise time of 260 ps, a fall time of 650 ps, and a pulse width of 1.6 ns. These findings indicate that the detector can be used as a sensor for Ī± radiation.
