SLED installed in HAM1 and most Diodes Cabled

Oli, Camilla.

Following work done in 84115 to repopulate HAM1 with some optical components, today Oli and I placed the SLED in position and placed all the diodes, most (not LSC POP A ) are cabled. Photos taken from -Y side and +Y side attached.

Apart from LSC POP A, they are all cabled up according to the cables in D1000313 BOM googlesheet. LSC POP A has a heli-coil that needs replacing before we can install the RF cable so neither cable are currently installed. ASC REFL A and B are in the incorrect position to allow for beam profiling before moving the the final position. LSC REFL A and B may need to be moved slightly but we need more of the correct size dog clamps to allow that.

We pulled the old helicoil and installed a new shorter helicoil into LSC POP A. All diode cables are now connected.

As we were running low on dog clamps, I swapped the bases of L2, M10 nd M12 to longer D1200683 mounting bases so that we can use the dog clamps where needed. Photos attached.
