  OVERVIEW 

   The Pixie-4 Express is a 4-channel digital pulse processor on a single 3U CompactPCI/PXI Express card. Designed for fast high-precision coincidence gamma-ray spectroscopy using HPGe detectors, scintillators, and silicon detectors, the Pixie-4 Express not only offers very high speed waveform acquisition but also pulse height measurements and time stamping for event reconstruction. Incoming signals are digitized at 125-500 MSPS with 12-16 bit ADCs, depending on the option purchased. The digital stream is used for triggering, pile-up inspection and filtering in real time. Waveforms can be stored in an onboard 256 MB FIFO. Pulse height reconstruction, accumulation of a 32K MCA spectrum for each chanel, and optional pulse shape analysis is performed on an event-by-event basis by a SHARC digital signal processor and an Artix 7 FPGA. Waveforms and spectra can be read out through the x4 PCI Express data interface at rates of several hundred MByte/s (theoretical limit 800 MByte/s per slot). The readout does not interfere with the data acquisition. Multiple Pixie-4 Expess modules can share clocks and triggers through the PXIe chassis backplane, which implements bussed and nearest neighbor signals between slots.

  The Pixie-4 Express can be customized on many levels for specific applications, either by XIA or an experienced end user. This includes the top level GUI, the C driver library, the DSP, the FPGA, and the hardware (ADC specs and analog front end). Consult our engineering staff for more infomation.
