A neutron-TPC (nTPC) is being developed for use as a fast neutron spectrometer in the fields of nuclear physics, nuclear reactor operation monitoring, and thermo-nuclear fusion plasma diagnostics. An nTPC prototype based on a GEM-TPC (Time Projection Chamber with Gas Electron Multiplier amplification) has been assembled and tested using argon-hydro...
This article presents the Digital Penalized LMS (Least Mean Square) deconvolution method for processing the X-ray polarimeter readout electronics output signal. The deconvolution filter is used to recover the detector signal high frequency component, which is lost due to the limited bandwidth of the readout electronics. The DPLMS deconvolution meth...
A multi-channel front-end ASIC has been developed for a fast neutron spectrometer based on Gas Electron Multiplier (GEM)-Time Projection Chamber (TPC). Charge Amplifier and Shaping Amplifier for GEM (CASAGEM) integrates 16+1 channels: 16 channels for anodes and 1 channel for cathode. The gain and the shaping time are adjustable from 2 to 40 mV/fC a...
