Subject: alignment of ITMs and PRM done 

   The alignment of the ITMs and the PRM has been done.

 As a result their reflections now come out at the REFL port successfully. 

The vacuum work is going on well as we scheduled at the last meeting.

 

(plan for tomorrow) 

 - installation of ETMY

 - installation of OSEMs on ETMY

 - alignment of the beam to the center of ETMY

 - alignment of the ETMY to the beam

 - final alignment of IP_ANG

 - setting up the oplev for ETMY

 - replace one of the steering mirrors at the RFEL path by a 0 deg mirror (see here).

 - setting up POX/POY (if there are time)

 

(today's activity) 

 - aligned the PRM tower such that the reflected beam goes back to exactly the same path as that of the incoming beam.

 - leveled the ITMY table because the OSEMs of ITMY had been completely out of range.

 - aligned the ITMY and ITMX in order to let the reflections back to REFL.

 - with a help from Osamu, we put a CCD camera, which actually had been used as OMC_T, just after the view port on the AP table.

 - looking at the CCD monitor we were able to see the reflected lights from the ITMs. (In fact sensor cards didn't help looking for the lights.)

  - playing with the alignment of the ITMs, we easily obtained Michelson fringes, which were also visible on the CCD monitor.
