| Overview: Neutron detector. A BF3 (Boron tri fluoride) detector tube enriched to 99% B10 is used to detect neutrons. When neutrons enter the detector tube they interact with the B10 in the following way: B10 + n => Li7 + a. The charge on the alpha particle generated in the reaction produces a signal across the input of the counter that is amplified and recorded. |
