The LB 6411 probe can be used as a portable monitor and as a stationary measuring instrument. Major areas of application are reactors and the nuclear fuel cycle in the nucleartechnical field, accelerators in research, and the use of neutron sources in the industrial fields.
The LB 6411 probe consists of a polyethylene (PE) moderator sphere with a composite 3He recoil proton counter tube, LB 6410, at its center. The probe also includes a high voltage supply and preamplifier.
For high energy applications at several hundred MeV or even higher there is a special version with an external layer of 10 mm lead available. The response to high energy neutrons is enhanced by utilizing spallation neutrons, which are generated in the lead.
