Description
Micromegas detectors are versatile gaseous charged-particle detectors.
They can be used for neutron detection with a suitable neutron/charged
particle converter, usually Li-6, B-10 or U-235. The detector consists
of a two-stage parallel-plate avalanche chamber with an ionization drift
region and an amplification region. The use of the microbulk technique
allows the use of printed circuit board techniques to produce a very
thin, radiation resistant, and low-mass detector with an amplification
gap of typically 50~micrometer. Micromegas neutron detectors have been
used both at pulsed neutron time-of flight facitlies and at a continous
neutron beams. An overview of MicroMegas detectors for neutron detection
and neutron reaction cross section measurements and related results and
developments will be presented.
