Neutrons produced by high-power lasers have revealed to be the brightest source available (in terms of number of particles per burst). Narrowing of the neutron spectrum and pulse duration is thus an ongoing research area in order to produce source suitable for probing materials or performing nuclear physics experiments.
Measurement of the neutron spectrum through a Time-of-Flight technique is one of the most reliable way of doing so. This uses, as shown below, a scintillator coupled to a PMT encase in a lead case. The Pb is mostly there to shield radiation coming not from the chamber, but from the walls, structures, etc surrounding the detectors. A tunnel for free line of sight of the scintillators to the target chamber should be managed in the Pb case.
Depending on your application, we will manage determining with you the most suitable ToF ensemble, and custom design and built it for you.
