Today's activities:
- EX pumpdown status: ~7.2E-8 Torr
- EX BRS: it is pumping: the roughing was already done, the small aux cart has been already disconnected, now it is only pumping on its own Ion pump
- On BSC8, the last 16.5" feedthru was replaced by a blank. In sum, 5 pcs. of 12" and 3 pcs. of 16.5" 3IFO feedthrus were replaced
- After a leaky calibrated leak was found on HAM8 RGA, it is still pumped now with an aux cart (which also needed some troubleshooting), and a pre-vent scan will be taken next week
