PIN diode and neutron spectrum measurements at the Army Pulse Radiation Facility

Neutron spectrum measurements using the foil activation technique have been made in two widely varying environments. One is an extremely high neutron-to-gamma field and the other extremely low. These measurements were used to characterize the fields and to evaluate the use of the DN-156 PIN diode for measuring 1 MeV equivalent neutron fluence in silicon (/spl Phi/1 MeV(Si)). The agreement between the /spl Phi/1 MeV(Si) as measured with diodes and as determined by the spectral measurements was within /spl plusmn/5%. A proton recoil neutron spectrum measurement was also made in the low gamma environment.<
