Preliminary Study of Temporal Performances of a Novel CVD Diamond X-Ray Detector
Based on the microstrip structure chemical vapor deposition (CVD) detectors, a coaxial detector with a single-ended connector has been manufactured using coaxial structure output components combined with isolated direct current circuits. The detector is mainly used for X-ray measurement of laser plasma. The detector uses a cylinder CVD diamond with the diameter of 4 mm. One end of the diamond is plated with a piece of grid electrode and the other end is plated with a piece of disc-shaped electrode. The grid electrode can ensure the normal application of the bias, but also allows X-ray to directly irradiate on the surface of the diamond. The temporal response performance experiment of the detector is tested on short pulse laser equipment. The results show that the rising time of the detector is 61 ps. The temporal performance study of CVD diamond detectors lays the foundation for the optimization of detectors.
