CAMAC standard high-speed precise spectrometer

The paper describes the CAMAC Standard Precise High-Speed Spectrometer for X-ray and gamma spectrometry designed for applications in a high-speed spectroscopy systems with requirement to obtain the high spectroscopy performance. The spectrometer contains the controlled. HV (high voltage) source, spectroscopy amplifier (later-amplifier), ADC (analog to digital converter) with buffer memory, CAMAC Grate controller hardware and software for PC. In this paper only the most important units, that determine quality and throughput performance of spectrometer are considered. The spectrometer has main features: maximum registration speed, pps, no less-150000; maximum input count rate, pps, -1000000; integral nonlinearity, %, no more -0.07; differential nonlinearity, %, no more -0.5; shaping symmetrical quasi-Gaussian; pile-up rejector dead time, ns, -100; ADC dead time, /spl mu/s, -1, 7. Spectrometric data are processed and displayed on PC.<
