Neutrino Flux Simulations

less than 1 minute read

Our neutron flux is measured, using the Multiplicity and Recoil Spectrometer (MARS) developed by Sandia National Laboratories. This portable neutron detector contains layers of EJ200 plastic scintillator and Gd-coated Mylar, and has 16 PMTs looking for any light. In this detector, an incoming neutron has a two-step process: it will cause protons to recoil within a scintillating layer and slow down, and it will then get captured on a Gd nucleus in a paint layer.
