  • Abstract
    The Gaseous Electron Multiplier (GEM) technology promises to deliver 3He based neutron detectors for a wide range of applications for the spallation neutron source ISIS. These devices offer a high rate capability and when used in conjunction CF4 as a quench gas they offer the potential of a sub mm resolution 2D detector for thermal neutron detection. The operation of these devices at elevated CF4 pressures (necessary for reducing the proton range) however has proved to be somewhat challenging. A program of work was undertaken at RAL to determine whether these devices are appropriate for deployment on the ISIS instruments.
