Watching a movie and cryostat temperatures in cryo corner,
waiting for it to cool.

A large window cut in a piece of foam so that we can map the beam
coming out of the primary mirror. We cut the circle with an
electrified wire, which left a very ugly exit wound. It was in
cleaning up this edge that I sliced my finger.

The knife and the damage done.

Our X-Y positioning rig. The chopper is attached to the front of the
lift. A ruler is taped to the ground, with a pointer indicating
side-to-side motion, and another ruler is taped vertically, with a
pointer indicating up-down motion. In this way we can quantify the
position of the chopper.

Marie (in a very tight spot) and Matt hook up the signals coming out
of the cryostat to the
receiver, the first set of warm (not cryogenic) electronics.
