Subject: put ETMY and aligned the beam 

  [Zach and Kiwamu]

 We installed the new ETMY tower and successfully aligned the beam to the center of ETMY.

 Also we finished the final alignment of IP_ANG.

 

 

(what we did)

 - took the old ETM out  from the chamber and put it on the flow bench at the X end.

 - with a help from Joe and Osamu, we brought the new ETM and put it roughly on place.

 - did a fine positioning of ETMY.

 - covered the ETM tower with a large peace of aluminum foil in order to see the spot on a video monitor.

 - stoled a compact video monitor that was sitting on the PSL table since we don't have any monitors at the Y end.

 - made a ~1cm hole on the foil as a target for the beam.

 - steered PZT1 in order to correct the beam position on ETMY. This is done by looking at the spot on the video monitor.

 - steered IPANG_SM1 to let the beam hit a steering mirror in the ETMY chamber which Koji installed recently.

     Now we have IP_ANG coming out from the viewport of the ETMY chamber.
