Neutron Energy Reconstruction and Fluence Determination at 27 keV With the LNE-IRSN-MIMAC MicroTPC Recoil Detector

The aim is to characterize the energy distribution of neutron fluence in the energy range 8 keV–5 MeV based on a primary standard: the LNE-IRSN/MIMAC microTPC. The microTPC is a time projection chamber. Time projection chambers are gaseous detectors able to measure charged particles energy and to reconstruct their track. The gas is used as a (n, p) converter in order to detect neutrons down to few...
