2-d-tof-pulse neutron detector

A 2-D-TOF-pulse neutron detector, comprising:

• a GEM-detector includes a drift-electrode covered with a neutron-converting material layer to generate electric field, plural GEM-boards covered with a neutron-converting material layer and a 2-D-TOF readout electrode to detect a 2-D position of electron, which is put in a chamber filled with electrolytic-dissociative gas;
• a 2-D-TOF readout integrated circuit including at least a 2-D-TOF readout electronic circuit to readout TOF, dose and 2-D incident position of pulse neutron, a time-clock electronic circuit to calculate TOF of pulse neutron by means of independent free-setup and a microprocessor unit to perform digital calculation of TOF, dose, 2-D incident position and transmission image of pulse neutron;
• an image processor to perform high-speed calculation of image data processing;
• whereby, the measurement of energy spectra, doses, 2-D-incident positions and transmission image of pulse neutron in the range of 1 eV˜100 keV is performed in the TOF-range of 0.1 μs˜200 μs and displaying the result of the measurement on the transmission image is performed in real-time.
