We took from TAMA the Qubig EOM box as well as a Sigma-type 30mm polarizer mount and a regular steering mirror mount. We also brought the VOPO equipment to the ATC cleanroom.

I also brought from FC cleanroom an adjustable-width key to try and unscrew the PZT spacer from the assembly (fig 6 of 3651) but the necessary force is ridiculously tight and I ended up just scratching the brass face again. I need to look for a better tool. Maybe this is why all serious squeezing experiments use the Advanced LIGO bowtie design instead.
