[X-front]
- Corrected the tilt of IP base by jack up/down of the corn bellows.
- Adjusted the position of IP by the stepping motors.
- Aligned the TM by the yaw picomoter in the BF.
[X-end]
- Corrected the tilt of IP base by jack up/down of the corn bellows.
- It was difficult to adjust the position of IP by the stepping motors due to the tight stopper setting.
- Vented the EXV chamber and open the top chamber.
- Released the stopper for IP more.
- Adjusted the position of IP by hand/stepping motors.
- Aligned the TM by the yaw picomoter in the BF.
- Closed the top chamber and started the evacuation.
- Followed the drift of IP position by the stepping motors during the evacuation.
[Y-front]
- Investigated the 70Hz peak in the spectrum of IP LVDTs. Changed the modulation frequency from 10,000Hz to 10,003Hz.
- Designing the yaw stepping motor mechanism. We need to procure 4 more motors.
