Before Christmas, I ordered four N-type and four SMA connectors from Digikey and they arrived in short order:
(It is an optical illusion, as both of the dielectrics are the same length)
I have also started to document the method used to build the cavity on the wiki.
Kevin , Adrian, Lin and Lukasz came over for Christmas dinner and we took a stab at soldering the cavity.
Under pressure from the hot copper, the plastic bulged a bit.
I have been thinking up a refined method of soldering in the copper liner, which I will attempt this week.
Unfortunately, this time of year is typically a busy one for TOF, but I hope to be back up to the university with the finished cavity soon.
