Just finished tfs for BSC2 ISI, they seem ok given the purge situation. I think I will have to wait until the dome is on to try to get better resolution tfs. Still have a couple other tests I want to do before sign off on the chamber, like some quick checks of HEPI range of motion. Should be done shortly.
A couple other checks I have done: a quick range of motion test on HEPI (driving +/-100um in x,y&z and +/-30urad in rx,ry,rz), locked spectra of seismometers (mostly checking the H1 L4C Mitch and I replaced this afternoon looked like the others), and free swinging cps spectra of the unlocked table. This last one somewhat suggests that the rubbing that BSC2 had may have been fixed (I found a st2 actuator cable grazing st2 where it shouldn't have been), previous ones taken in vac show the St2 corner 1 cps were seeing a bunch of extra motion below 1hz, this is no longer visible, as shown in attached spectra.
I'm heading out in a second to lock HEPI and ISI to prep for dome install.
