Multiparametric DAQ Software for Physics Applications

  • Software for simultaneous DPP acquisition, including
    DPP-PHA, DPP-PSD and the new DPP-QDC
  • Multi-board management
  • Synchronization of multiple boards even from different families
  • Correlation between different channels
  • Simultaneous plot of waveform, energy, time, PSD, and TOF spectra
  • Energy calibration
  • Digital Constant Fraction Discrimination for fine time stamp interpolation (pico second intrinsic resolution)
  • Selectable filters on energy, PSD, and Correlation
  • Advanced data saving options:
    - Data from board is recorded for the whole acquisition run
    - Time ordered recording of channels acquired data (list mode)
    - Spectra saving
  • Data can be retrieved offline to make additional filters and analysis
  • ROOT format data saving
  • Add-on for ROOT integration
CAEN Multi-PArameter Spectroscopy Software (CoMPASS) is the new software from CAEN able to implement a Multi-parametric Data Acquisition for Physics Applications, where the detectors can be connected directly to the digitizers inputs and the software acquires energy, timing, and PSD spectra at the same time.

CoMPASS can manage all the CAEN Digital Pulse Processing Firmwares (DPP-PSD, DPP-PHA and DPP-QDC1), multiple boards acquisition, even in synchronized mode, and the event correlation between different channels (at hardware and/or software level). Furthermore it shows at runtime the energy, time and PSD plots, applies energy and PSD cuts, calculates and show the acquisition statistics (trigger rates, data throughput, etc...), saves output data files (raw data, lists, waveforms, spectra) and use the saved files to run off-line with different processing parameters.
