Measurement of the Efficiency of a Neutron Detector Array

In this work we describe the development of an array of 7 neutron detectors through the use of solid plastic scintillating material and photomultiplier tubes. Furthermore the nuclear reaction d(D,3He)n produced with a Tandem accelerator at ININ was used to measure the energy dependent neutron detection efficiency of our detectors with the associated particle technique.

Characterization of a Fast Neutron Detection System With Large Angular Coverage and Granularity for Physics Studies and Applications

This work presents a review of fast neutron detection, with an emphasis on the use of plastic scintillating materials. We developed neutron detectors both at the Instituto de Fisica, UNAM and at the Tandem Accelerator Laboratory, ININ. We will describe in detail our detectors and their characteristics. We will present some results on the development of a large position‐sensitive neutron detector in two dimensions. In particular, we present a phenomenological formula that describes the complex dependence of the amount of light reaching a detector as a function of the position of the light source within the scintillating material. First measurements with a very small number of detectors are presented and show encouraging results.
