The hit position reconstruction algorithm for neutron and gamma imaging detectors based on artificial neural networks

Penghui Wang, Jifeng Han, Yangmei Chen, Peng Hu et autres

Neutron and gamma imaging have continuously expanded applications in nuclear safety, national security, and materials characterization. The hit position reconstruction algorithm is a key issue that constrains the image fidelity and accuracy. This work has developed a two-dimensional planar neutron and gamma …

Neutron Energy Spectrum Measurement and Unfolding Method Based on a Single Long Lithium- or Boron-Doped Scintillator

Jingwen He, Jifeng Han, Hua Cai, Danping Chen et autres

This work proposes a simple neutron energy spectroscopy based on a single long lithium- or boron-doped scintillator coupled to two photo-electronic devices (PMTs) on both ends. The principle is that the neutron’s capture position [depth of interaction (DOI)] inside the scintillator is …

Using graph neural networks to reconstruct charged pion showers in the CMS High Granularity Calorimeter

Muhammad Aamir, G. Adamov, T. Adams, C. Adloff et autres

Abstract A novel method to reconstruct the energy of hadronic showers in the CMS High Granularity Calorimeter (HGCAL) is presented. The HGCAL is a sampling calorimeter with very fine transverse and longitudinal granularity. The active media are silicon sensors and scintillator tiles …

Detection of 10 to 300 keV fast neutron using CLYC, CLLB and CLLBC scintillators

Feixu Ren, Jifeng Han, Ruiqiang Song, S. Qian et autres

Abstract The neutron and gamma detection performance of multimode scintillators including Cs2LiYCl6:Ce (CLYC), Cs2LiLaBr6:Ce (CLLB) and Cs2LiLaBr6-,x Clx:Ce (CLLBC) were tested in this work. The energy resolution for 662 keV gamma rays was 4.19% for CLLB, which was better than that of …
