Double-GEM based thermal neutron detector prototype

Nine Element Si-based Pillar Structured Thermal Neutron Detector

Solid state thermal neutron detectors are desirable for replacing the current He based technology, which has some limitations arising from stability, sensitivity to microphonics and the recent shortage of He. Our approach to designing such solid state detectors is based on the combined use of high aspect ratio silicon PIN pillars surrounded by B, the neutron converter material. To date, our hig...

A new active thermal neutron detector.

This communication presents the main results about the design and in-house fabrication of a new solid-state neutron detector, which produces a DC output signal proportional to the thermal neutron fluence rate. The detector has been developed within the framework of the 3-y project NESCOFI@BTF of INFN (CSN V). Due to its sensitivity, photon rejection, low cost and minimum size, this device is su...

Prototype developments for a high-resolution neutron detector at RB

A detector for momentum measurements of highenergy neutrons in the energy range 200 MeV to 1000 MeV is being developed for the RB experiment at FAIR. The detection principle is based on a combination of converter material and subsequent detection of charged particles from reactions in the converter material. Multigap Resistive-Plate Chambers (MRPC) are used for the detection of charged particle...

Development of Thermal Neutron Detector based on Lithium Tetraborate (LTB) Single Crystal

High quality single crystals of Ag doped lithium tetraborate (Li2B4O7:Ag) have been grown using the Czochralski technique. The presence of naturally abundant 6Li and 10B in the crystal has been gainfully utilized to fabricate compact devices to measure thermal neutron fluxes from various sources. To achieve a high signal-to-noise ratio, a thermally stimulated luminescence (TSL) measurement set-...
