With detectors still on the floor we check signals and found
that D4 gives no signal with PA power.  Two power supplies/cables were checked.
The detector was still working just before Jungclaus experiment. In July it was working.

Temperature monitors OK: 76-80 units

We mount both CLovers in position and make all connections.

We apply HV and check the resolution of G7.

As can be  seen in the attached figure the calibration used last year
is still pretty good
