Back to [[ThermalNeutronDetector]] Initial meeting. Agreed to make a small prototype. Notes from Steve by e-mail: {{{ After reading Eric''s message, I think we should plan for a prototype 30 cm long, 20 cm wide, with 30 cm long 30 micron diameter gold plated tungsten wires. The wire pitch should be 5 mm, and the wires should be 5 mm below the top grounded plate and 5 mm above the bottom grounded plate. Initially, we will have lithium foil on the bottom only, and if that works we will have a lithium plate on top as well. We should have a Faraday cage, as Eric suggests, around the whole thing. And we should have a preamp for each of the 40 wires. It would be nice if we could sum all the wires. }}} {{{ I am getting a portable Ortec MCA that accepts preamp signals at the input (see attached). It would be nice if the summed preamp specs are compatible with this. }}} My notes [http://ohm.bu.edu/~hazen/Ahlen_Neutron/2010-10-05_notes.png PNG]
