[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.
