We wrapped space between IMM chamber and PRM chamber in aluminum foil to avoid dirting the inside of chambers (2017/8/7).
We are planning to align IMMT1 and IMMT2 so that we can measured beam profile.
This ((1)- http://klog.icrr.u-tokyo.ac.jp/osl/?r=2381) reported
that they placed bKAGRA IMMT2 roughly at where iKAGRA IMMT2 was.
I checked this position coressponds to bKAGRA IMMT2 position
i.e. (-24.4940 0.2907 0.0001) in optic coordinate(Aso-san data 20120607).
So maybe IMMT2 was placed on the postion of bKAGRA IMMT2 in iKAGRA.
We moved IMMT2 from the position of (1), shifted the base of IMMT2(which adjust the height of IMMT2)
and aligned the pitch ofIMMT1 and IMMT2.
Finally We put IMMT1 on the same position as iKAGRA and put IMMT2 on the same position as (1) (bKAGRA position).
Images attached to this report show the present location of IMMT1 and IMMT2 (roughly bKAGRA position) (2017/8/8).
