The CLAS12 Central Neutron Detector

Deeply Virtual Compton Scattering on the Neutron with CLAS12 at 11 GeV

Measuring Deeply Virtual Compton Scattering on a neutron target is one of the necessary steps to complete our understanding of the structure of the nucleon in terms of Generalized Parton Distributions (GPDs). DVCS on a neutron target allows to operate a flavor decomposition of the GPDs and plays a complementary role to DVCS on a transversely polarized proton target in the determination of the G...

Simulation of a Neutron Detector for Real Time Imaging Applications

Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...

Simulated CLAS12 Neutron Detection Efficiency in the Forward Time-of-Flight System

We have simulated the production of quasi-elastically (QE) scattered electrons and neutrons in CLAS12 with the physics-based, CLAS12 simulation package gemc. The electron events were reconstructed with Socrat. We have studied the properties of the deposited energy and efficiency of the CLAS12 FTOF system to establish a baseline for the future measurement of the neutron magnetic form factor in E...

Amorphous Silicon Based Neutron Detector

Perforated Semiconductor Neutron Detector Modules

Compact neutron detectors are being designed and tested for use as low-power real-time personnel dosimeters. The neutron detectors are pin diodes that are mass produced from high-purity Si wafers. Each detector has thousands of circular perforations etched vertically into the device. The perforations are backfilled with 6 LiF to make the pin diodes sensitive to thermal neutrons. The prototype d...
