Type-B: (PDF/MPP)
Type-A (Takahashi)
Past week report
[X-end]
- Adjusted the weight of cryo-payload (CP).
- Adjusted the height of F1, F2, and F3 using the FRs. The height of BF was set to 80mm.
- Set the height of F0 keystone to 5.5mm adjusting the weight on the keystone.
- Aligned the CP using the yaw adjustment screw in F0.
- Adjusted the position of secondary coils for the BF damper.
- Released the IP. Adjusted the horizontal FRs. Applied the DC control.
- Closed the top chamber.
[X-front]
- Cabled the LVDT-Actuator and the FR in the F1.
- Mounted the F1 onto the EQ stop with the maraging wire.
- Cabled between the F2 and the F1.
- Calibrated the LVDT of F1.
- The height of keystone was too low without additional weight on the F2.
- Compressed four blades.
- Replaced the blade of FR from the F2 type to the F1 type.
- Measured the transfer functions. The frequency of F1 was 0.3Hz.
- Found that the F3 is not working.
- Disassembled the F1 stage to lift up the F3.
Plan for coming weeks
[X-front]
- Recover the F3.
- Go buck to the F1 stage.
- Prepare for the pre-isolator.
Type B (Mark)
Past week report
Report for week of 3/26
BFs:
- BF No. 1:
- Fujii-san finished tuning. Optimal load: 52.15[kg]. Resonance frequency: 0.37[Hz]. Optimal height: 64.7[mm].
- We wired the LVDT, Picomotor and Steppermotor.
- We measured the keystone tilt at different points and the differences are within 0.1[mm]
- We added cable clamps to the base.
- BF No.7:
- Tanioka-san and Fujii-san replaced the blades corresponding to the BS for the SR type blades.
- The yoke position was corrected.
- The fishing rod was assembled.
- Compression tuning is ongoing.??
SFs:
- Hirata-san and Tanioka-san set up the frame to check the SFs.
- SF (B2-5):
- Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap. The optimal load changes about 250[g]. The cap didn't come out smoothly.
- We measured the keystone tilt at different points, and the differences are within 0.1[mm] (65.5, 65.5, 65.5, 65.4)
- SF (B2-6):
- Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap (On going?).
- We measured the keystone tilt at different points, and the differences are within 0.3[mm] (63.7, 63.5,63.8, 63.8)
SR3/SRM:
- Kozu-kun and Enzo finished the SR3 in-air cabling.
- Enzo prepared the SR3 and SRM rack in parallel (On going).
- The drawing of the ballast masses are almost done. Shoda will ask for quotation soon.
SR2:
- Hirata-san tested the safety bars in the SR2 area.
- We got new power supply for the SR2 Rack. Before, the power was coming from the BS rack.
BS:
- After re-starting the computer, the issue reported last week was fixed.
- Kozu-kun and Enzo helped Enomoto-san troubleshooting the BS Oplev issue (On going).
Shipping:
- We received the LBB parts for SR2.
- We received the Payload parts (IM and IRM) this morning.
Control Issue:
- BS
- The whitening filter of only IMH high power coil driver is on somehow, without anti-whitening filter. It should be fixed at some point, maybe after Phase-I.
- SR2
- BIO issue was fixed and TFs of IM, BF, and SF are measured.

==== Discussions =====
- 52.15kg optimal load for BF No.1 may be too low. We need to change the ballast masses for the IM.
- Aso will check the delivery date of SR3 with Hirose-san.
Length sensing OpLev of BS is strange. We need a calibration.
