Subject: Strain relief mounted 

(Thu 28 October)

All strain relief extension plates mounted behind the wires, using SS countersunk bolts (not silver plated).

Inserting bottom part of MACOR strain relief causes wires to bend too much with strain placed on DSSD. No reasonable way to proceed like that.

Opted to move hard kapton coated copper wire to line up with holes in top MACOR strain relief, and clamp the wrapped wire bundles between top MACOR strain relief and extension plate on bottom.

Results good. No significant movement when wires are moved or motors actuated. See videos - password abcd1234

Mounted plate with MACOR shield on other rod. Connected thermocouples. Re-mounted 2x UHV1400 getters.

 

 

With help from OH attempted V-I test of detectors. SHV to 2x lemo broken (faulty lemo connector). Had to borrow AID@DESPEC cable.

Diode function OK. VI tests OK but inconclusive. Both DSSDs drain current when voltage is applied, but current not quite stable. Light leak very likely. Will attempt again after closing.
