Digital spectrometer and multichannel DSP modules
PXI-format digital signal processing modules and multichannel readout cards capable of real-time pulse processing, demultiplexing, and spectrum generation for detector arrays.
Low-background alpha counters and analytical detector systems
Counting systems designed to reduce background and sample-window separation artifacts for alpha emissivity measurements.
Detector readout kits for neutron and photon detection
Integrated solutions combining scintillators, photodetectors, and digitizers for neutron detection and pulse-shape discrimination.
Pixie-Net
The Pixie-Net is a 4-channel digital pulse processor for radiation detectors in desktop format with integrated Linux operating system. It supports coincidence gated acquisition, pulse shape analysis, and constant fraction timing, designed as a cost-effective entry-level version of the Pixie pulse processor series.
Pixie-Net XL
A nuclear data acquisition system with sub-nanosecond time resolution for time-of-flight style measurements, referenced in a publication.
Pixie-16
The Pixie-16 is a data acquisition system for nuclear physics and other applications requiring coincident radiation detection with large number of channels. It's based on the CompactPCI/PXI standard.
