Construction and Calibration of a Fast Neutron Scintillation Spectrometer

Abstract
A quadrupole coincidence scintillation counter telescope has been constructed for neutron studies with the University of Rochester 130‐inch synchrocyclotron. A calibration of pulse height vs proton energy has been obtained for the fourth crystal of the telescope. The response of this crystal to monoenergetic protons has been found to be in fair agreement with calculations for the distribution of energy loss for protons, made using the method developed by K. R. Symon. The instrument covers the range from about 50 to 240 Mev in recoil proton energy.
