Moved an optical bench, which was left outside of the cleanbooth in the -Y direction of the MCF chamber, with two bishamons and a crane, and placed it in the -Y direction of the PR2 chamber (Fig. 1). On the bench, optics for POP and GreenX will be setup in the (near?) future.
- Before this work, a K400 seal flange was replaced with the one for ICF152; see here.
-
Before the optical bench came, 8 anchor holes with which the bench's legs will be fixed, were cleaned in the usual manner, but after we brought the optical bench there, we found the legs dimenstion and the locations of the anchor holes could not match!! (for instance, Fig.2)
-
So we left the optical bench without any anchor clamping so far; if someone needs anchor clamps, please do it yourself...
-
A pair of Koarch filters are left in the -X direction of the PR2 chamber.
Note1: firstly we tried to lift up the optical bench by the two bishamons, but whose blades could not reach the beams streched at the bottom of the bench legs, so we needed to insert some stiff stuffs between the blades and the beams.
Note2: In the most -Y direction, the floor had been covered by a plastic sheet with yellow-black stripe tapes; as far as I know, no one knew who did this, but we estimated the sheet was placed for stopping some water fountain. It seemed a part of the plastic sheet would interfere the legs of the optical bench, so we partly removed the plastic sheet (Fig 3).
