LUPIN BF3
Neutron rem counter for pulsed fields
Monitoring unit for neutron H*(10) with unusually good performance in pulsed radiation fields, for example around accelerators. The rem counter has a BF₃ proportional counter in a cylindrical moderator and built-in electronics that calculate the H*(10) rate every second and send it to a SATURN ratemeter. The LITE version is lighter and measures up to 20 MeV.
