H2 PSL installation

The exterior and interior walls of the enclosure have been primed and will be painted tomorrow. Feedthru holes were drilled and PVC pipe was installed on all but 2 feedthru locations. Holes for EMT conduits were also drilled into the roof, at 3 of the 4 locations. No HVAC work today.

There were several dust spikes above 20000 in both 0.3 and 0.5 micron, but Apollo was also drilling by HAM7, which contributed to the dust counts.
