We payloaded the ISI Keel with the 600 lbs per D1002266-v1 (v1 really?); each 150lb stack sitting on 8 in2 of 1/4" thick viton. See photo.
With that completed we unlocked HEPI and floated the platform (~15000lbs) on the HEPI DSCW Springs. Next we shot level/elevation of the Optical Table. See attachment for log notes.
The table actually started out pretty good, I thought we had disturbed it more during float. The level had about 0.5mm runout and the elevationi was low 1.3 mm--all within spec. We adjusted anyway to be 0.3mm runout and 0.2mm high.
Mitchell then joined Jim in chamber and moved the ACB deep into the Spool. I then helped Betsy put the lift table into the chamber. Jim & Mitchell moved the Table into the Spool and set the ACB atop the table. Betsy & Travis were working to install the retroreflector for the IAS Y shot while Jason & Doug were getting their equipment readied,
