Description

The X-PIPS™ Detector is a spectroscopy sub-system sensitive to X-rays and low-energy gamma rays. It comprises a hermetically-sealed silicon detector element with a low-noise FET assembly and Peltier cooler, a reset type preamplifier, a HV bias supply, and a temperature controller. The detector element and FET are cooled and regulated to a fixed temperature, ensuring stable operation in changing environmental conditions. The Beryllium entrance window is 25 μm (1 mil) thick.

The preamplifier has a unique digitally-controlled source reset mechanism (US Patent 6,587,003) providing fast reset time and excellent count rate performance. A reset inhibit signal is available to prevent storage of spurious pulses due to transient reset effects. The width of the inhibit output pulse can be set from 10 μs to 650 μs.

The energy resolution is guaranteed within an ambient temperature range of +10 °C to + 30 °C with the default factory settings. The unit can be optimized for other temperature ranges on special order.

The X-PIPS Detector has an internal collimator (standard silver) for improved peak to background.
