Thermal-neutron detection based on the Gas Electron Multiplier

Future high luminosity spallation neutron sources put strenuous demands on detector performance. This research has focused on applying the Gas Electron Multiplier (GEM) to meet most criteria, most notably mm spatial resolution, 1 MHz local countrate (per pixel) and 70% efficiency for 0.18 nm neutrons. The choice for this detector type was made...

A Novel Scanning Land Mine Detector Based on the Technique of Neutron Back Scattering Imaging

The neutron back-scattering (NBS) technique is a well established method to find hydrogen in objects. It can be applied in land mine detection taking advantage of the fact that land mines are abundant in hydrogen. The NBS technique is suitable for land mine scanning e.g., seeking for land mines with a moving detector system, because of the high...

Neutron imaging and tomography with MCPS

A neutron imaging detector based on neutron-sensitive microchannel plates (mcps) was constructed and tested at beamlines of thermal and cold neutrons. The mcps are made of a glass mixture containing 10B and natural Gd, which makes the bulk of the mcp an efficient neutron converter. Contrary to the neutron-sensitive scintillator screens normally...
