The JET neutron profile monitor provides the measurement of the neutron flux along 19 collimated lines of sight from which the neutron emissivity profile can be obtained through reconstruction based on inversion methods. The neutron detectors are liquid organic scintillators featuring n/γ pulse shape discrimination. A recent digital upgrade of the neutron profile monitor acquisition system (200MSamples/s...
A new architecture has been developed for the ENEA-Frascati neutron/gamma Digital Pulse Shape Discrimination (DPSD) system. The system (FPGA-based, 200 MSamples/s, 14 bit ADC resolution) has been upgraded to 4 input channels; higher versatility has been obtained through the implementation of a soft processor in the FPGA. The FPGA-embedded processor enables to create software programs written in plain...
Neutron/??-ray Pulse Shape Discrimination (PSD) is a common technique applied to detectors (liquid organic scintillators) employed in neutron diagnostics for fusion plasmas. For example, NE213 scintillators, coupled with analogue PSD modules are in operation at JET (Joint European Torus) in the radial and vertical neutron camera and also in a compact neutron spectrometer system. However, these analogue...
