Position Sensitive 2D Detectors

  • for regular in-situ NG diagnostic
  • cross-section neutron intensity distribution (TOF application-the diagnostic is wavelength dependent)
  • Custom designed based on active area and spatial resolution requirements
  • Position encoding technique: delay line
  • Anode and cathode wires: Gold-Tungsten
  • Filling gas: Helium-3 and CF4
  • Dynamic range: single neutron detection
  • 5 preamplifiers built in
  • Commercial CFD and TDC can be connected or vendor-supplied
  • XY projection, integration; open interfaces for easy integration to existing software

Test "Black" Detector

  • for efficiency test
  • flux measurement (TOF application-the diagnostic is wavelength dependent)
  • advantage to tube: high count-rate capability, planar arrangement: constant active gas depth
  • Model No. MWBD-30

  •  

PSD Data Acquisition Unit

  • Model No. LisTDC-312
    • With ACAM chip/a (serial/parallel)
    • With ACAM chip/b (Time Stamp)
    • Only FPGA (Isherd)
  • Measurement of a number of parallel events
  • Data gathering
  • Series of filters
  • Filtering: e.g. by wavelength intervals
  • Histogram generation
  • Events are recorded in lists
  • Lists are processed into histograms
  • Lists remain available for revisiting
  • Common 2D Event List
  • Spectral 2D Event List
  • 2D information (X & Y) extracted from Stop signals
