This page documents a electronics for a thermal neutron detector being developed for Steve Ahlen starting in Oct 2010. The ultimate goal is to build a replacement for the existing detector technology based on the now scarce 3He isotope.

The final detector must be 2m x 30cm x 12cm. It is anticipated that it will use 6Li foils as the active material, with HV wires at < 1200v in a drift chamber configuration for readout.

Meeting Notes

If the wire pitch is 5mm and we want to readout every wire, then the preamp pitch must match. This likely implies thin "hybrid-style" preamp boards mounted vertically on a motherboard.
