Though Arnaud had posted a few of the pictures from our B&K hammering session of ITMX in BSC3 (see LHO aLOG 8497), I post the rest here because I got more pictures that are not necessarily B&K related. I attach four .pdf albums, captioned below; along with a few of the best publicity photos attached in raw form.

-  Nothing to be alarmed by here, but I noticed that tons of cabling were draped from ST0 of ISI-ITMX to their respective feedthroughs in rather hap-hazard ways, and I was worry about potential shorting of isolation between the suspended payload of HEPI and the Chamber. I mentioned this to Jim, and he quickly assured me that the cables are still in a transient state, and will most certainly be cleaned up before the chamber is closed up. I merely post for posterity, so we (i.e. not just folks in SEI) remember what *not* to do.

- Just a few more pictures from the B&K hammering session, indicating where I was hitting and a few action shots. As I said, Arnaud has posted most of these already in LHO aLOG 8497.

- It's always good to get some shots that can be later used for posters and talks. Here's a fashion show of H1 SUS ITMX.

2013-11-13_IXArmCavityBaffle.pdf
- A couple of things to note here:
(1) The first two pages show just how incredibly close the ACB is to the QUAD structure as a result of the move decreed by IAS. In page two I'm trying to hold up a 3/16ths allen key up for perspective, but it didn't work out so well. I would estimate the gap at-closest-approach is no more that 5 [mm]. It just gives me the willies. Especially since I gave the ACB a few milli-Jeffs of calibrated excitation, and it started waggling with reasonably high Q at ~5-10 [Hz]. Is the fundamental resonance of this suspension really that stiff / high-in-frequency? Hurumph.
(2) This is the first time I've seen the suspension system up-close and personally, so I wanted to get some good shots of it. Very interesting design...
(3) There's still some tooling lying around on the baffle itself. We should make sure to grab these before chamber close-out.
