Past week report
[X-front]
- Suspended the filter chain from the TF.
- Attached two cross tubes and four feedthroughs onto the top chamber.
- Cabled from the upper small hexagon to the feedthroughs.
- Replaced the guide clamps for two blades with thin guards. Compressed the blades by 3~8mm respectively.
- Released the keystone of TF. The height of keystone was too low without additional load. Frequency was 1.4Hz (too high).
- Repaired the thread hole for the hook screw for the SF damper.
- Attached the EQ stop anchor. Adjusted the horizontal position of the EQ stop.
- Checked the LVDT signals. Found the F1 keystone touching to the secondary coil. When the F1 sit on the release sensor, it was free.
- Set the LVDT drivers to the rack. Calibrating the LVDTs for the BF damper.
