Temporal and spatial detection of charged particles by neutron-induced reactions – XyMegas

Submission summary

Micromegas detectors are used in a variety of physics projects including in low-energy nuclear physics and neutron-beam related detectors. With this proposal we intend to develop a “transparent” orthogonal strip Micromegas neutron detector with unprecedented position and time resolving data acquisition capabilities, for use at the major neutron time-of-flight facilities. Typical usages are neutron flux and reaction cross section measurements, and neutron beam imaging. A very thin detector with both a segmented anode and segmented mesh, coupled to the dedicated VMM3 chip developed for Micromegas detectors, will lead to an innovative detection device. The new detector will also be used as a time-projection chamber (TPC) to investigate angular distribution measurements of reaction particles of interest for nuclear reaction studies and nuclear data. The TPC mode will be tested in the neutron beam of GELINA with light charged particles and fission fragments.
