Recently I advertised the availability of some 3BP1 and 3JP2's for
trade. I received a request, but lost the e-mail reply. I now find I
have a few 6342 MPT's with socket and simple preamps. These are mounted
with irises as a simple light detector. Additionally I have some 6655
mounted with one inch scintillators, again they are same socketed with
internal preamp.
I also have 723A/B's, transmitters and 1N23 receivers (with small
horns), and polarizers. All are mounted on notched boards meant to sit
on wooden "optical benches". Gate Keeper will very much appreciate
good homes for them -- not this one. I don't remember about the MPT's,
but all the other stuff is for the Berkeley Physics LAB.
