Summary Report
Type-A
Type-B
* In BS, the IM picomotor cable was checked because pin 8 has a connection to ground. It was determined that the problem is deep within the chamber, and we cannot fix it from outside. The yaw picomotor should still be functional because such a pin is connected to ground at the driver.
- In SR suspensions, we withdrew security stop screws to allow larger motion of the whole suspension in the longitudinal direction by approximately 5 mm. Clearly, we didn't move the stop screws around the F1 filters.
- We installed dial gauges in all four Type-B chambers underneath the mushroom heads. The aim is to monitor the motion of the chamber when pump down happens.
- Yokozawa-san took pictures of the inside of the chambers with the 360 degrees (4pi sr) camera.
