Abstract

The PARIS calorimeter is an apparatus intended for the future SPIRAL2 facility in Caen, France. It will comprise a spherical shell of scintillators detectors making extensive use of LaBr3(Ce) - a relatively new material with excellent energy resolution (∼3% at 662-keV). The individual detector modules will be of a phoswich design where the fast LaBr3(Ce) crystal is optically coupled to a slower conventional crystal like NaI and the scintillation light is collected with a single photomultiplier tube.

Abstract

The application of a CAEN DT5730 digitizer unit for fast neutron metrology is explored. Measurements were made at the Accelerator for Metrology and Neutron Applications in External Dosimetry (AMANDE) monoenergetic neutron facility of the IRSN, France, over a neutron energy range from 1.2 to 7.0 MeV using a BC501A scintillator. The DT5730 digitizer and an analog system based on NIM electronics and an MPA-3 multichannel analyzer acquisition unit were used, under identical beam conditions, for data acquisition. Several observables were compared between the two systems including the quality of pulse shape discrimination (PSD), neutron energy distribution derived from unfolding analyses, and deadtime effects over a range of beam currents from 0.1 to $5.1~\mu \text{A}$. The suitability of the digital system for fast neutron metrology measurements both in the laboratory and in workplace fields is discussed. [ABSTRACT FROM AUTHOR]
