After the great success on Tuesday 2026-06-02 solving the mystery with the MEAS IFO's efficiency drift (LHO:90455), we declared victory and spent the morning packing up all of the clean assembly to be ready for install.

We 
   - Weighed the mass of what components will be suspended on Stage 1 of the HAM3 ISI (see LHO:90504)
   - Packed up the optical fiber feedthrus (see Attached Pic #1)
   - Packed up the ISIK Transceiver and its in-vac cabling on a roll-able clean cart quadruple wrapped in foil (see Attached Pic #1)
   - Packed up the two D25 to D25 pico-motor and PD cables that span from Cable-Table-Bracket #3 to the HAM3-D6 feedthrough.
   - Powered down, disconnected, and packed up 
       . the laser prep chassis (see bottom of Attached Pic #3)
       . the transimpedance amplifiers (no pic)
       . the commercial RF source Keysight 33600A (no pic).
       . all in-air cabling, including mock-feedthrough

The fiber-coupled NPRO is still set up, but the laser is shuttered and key'ed off.

Thank you optics lab, and good luck trail-blazing to you, SPI pathfinder!
