OVERVIEW
The Pixie Link is a multi-channel digital pulse processor designed for high-precision experiments using HPGe, scintillator, or silicon detectors. Besides nuclear spectroscopy, the Pixie-Net XL can be used for neutron/gamma discrimination, time-of-flight measurements, and coincidence/anti-coincidence measurements. Built on XIA's proven digital pulse processing, the Pixie Link combines an embedded POSIX SMB real-time OS with a high-speed FPGA. This combination provides you not only with energy and time, but also with digitized waveforms, CFD, and pulse-shape analysis. These data make the system capable of instrumenting nearly any experiment that requires robust data acquisition. The Pixie Link delivers a complete, network-integrated solution for demanding applications. It works with commercial off-the-shelf networking gear making integrating with existing networks much easier. The desktop form-factor makes the system easy to install near the detectors. Co-location shortens your cable lengths and can reduce your overall experimental costs.
