Prospects in MPGDs development for neutron detection

Compared to Multi Wires Proportional Chambers (MWPC), Micro-Pattern Gas Detectors (MPGD) used in HEP to detect MIPs offer better spatial resolution, counting rate capability, and radiation hardness; their fabrication is also more reproducible. Provided similar advantages are applicable to detect neutrons, MPGDs might contribute significantly to the development of neutron scientific instrumentation. In order to evaluate the prospects of neutron MPGDs, it is worth knowing the applications which would benefit from a gain in performance, and if they offer a competitive alternative to conventional 3He detectors. These questions have been at the focus of the workshop "Neutron Detection with Micro-Pattern Gaseous Detectors" organized by RD51 in collaboration with HEPTech, which took place at CERN on October 14-15, 2013. The goal of this workshop was to help disseminating MPGD technologies beyond High Energy Physics, and to give the possibility to academic institutions, potential users and industry to meet together. This summary article starts with a short summary of the state of the art of MPGD techniques for HEP; then specificities in the design of neutron detector are described; the consequence of the 3He shortage are briefly discussed; requirements for neutron scattering science at current facilities and at the future ESS are described; finally, we give some recommendations about possible directions where we believe the development of neutron MPGDs is of particular interest for possible use on neutron scattering instruments.
