High rate, low noise, x-ray silicon strip detector system
Abstract
An x-ray detector system, based on a silicon strip detector wire-bonded to a low noise charge-sensitive amplifier integrated circuit, has been developed for synchrotron radiation experiments which require very high count rates and good energy resolution. Noise measurements and x-ray spectra were taken using a 6 mm long, 55 micron pitch strip detector in conjunction with a prototype 16-channel charge-sensitive preamplifier, both fabricated using standard 1.2 micron CMOS technology. The detector system currently achieves an energy resolution of 350 eV FWHM at 5.9 keV, 2 mu s peaking time, when cooled to - 5 C.
