Calibration measurements for the efficiency and response function of the NE213 scintillator by a /sup 252/Cf spontaneous fission source-application of a two-dimensional pulse height analysis system

Abstract

Abstract-This paper describes calibration measurements for the efficiency and response function of the NEZ13 scintillator as an application of a iwo-dimensionai pil\se height analysis system. In this method, a 2s2ef spontaneous fission' sou.rce with a continuous spectrum is employed by taking each fission event as a pulsed neutron soutce; and the effiCiency . and response function of the NE213 scintillator can be estimated by the twodimensioDlil measurements of the time-of-f1ight spectrum (neutron energy spectrum) and puise height spectrum.'
