Calculator of 1-MeV equivalent neutron fluences

1-MeV-neutron equivalent fluence calculatorThe 1-MeV-neutron equivalent fluence for exposures of silicon components on the beamlines of PIF & NIF is calculated on this page using the method outlined in the ASTM E722-14 standard. The energy-dependent dose damage ratio data used in the calculation is as compiled by A. Vasilescu and G. Lindstroem and shown in this figure:
