X-ray detector X-PIPS™

Detector System Includes: • Thirteen Silicon Drift Detectors (SDD) • 1 mil (25 μm) Be Window • CMOS Preamplifiers • HV Bias Supply • Cryogenic (pulse-tube) cooled The X-PIPS™ detector array is a spectroscopy sub-system sensitive to X-rays and low-energy gamma rays. It comprises of thirteen Silicon Drift Detectors (SDD) with a low noise CMOS reset type preamplifier, a HV bias supply and a cryogenic cooler. The detector elements and CMOS preamplifiers are cooled and temperature regulated, ensuring stable operation in changing environmental conditions. The Beryllium entrance window is 1 mil (25 μm) thick which allows for measurement of X-rays as low as 1 keV. The CMOS preamplifiers have a fast reset mechanism which reduces dead time and allows the detector to perform well at high count rates. The high performance SDD combined with a CMOS preamplifier provides a very fast, low noise response, which results in extremely good energy resolution with fast peaking times. The signal rise time is well below 50 ns which makes for excellent energy resolution at high count rates. The energy resolution is guaranteed within an ambient temperature range of +10 °C to + 30 °C with the default factory settings.
