| == Next Plan == * Detach the remaining white tapes just before closing the chamber; be noted that there are white tapes on the PEEK connectors at the inside of the flanges. * Torque completely the bolts which are fixing the upper and the lower base plates. * Insert metal gaskets before torquing the ICF203 flanges with Dsub connectors. * Attach an oplev viewport * Setup the oplev for TMS-VIS * Consider why the green ghost beam is not observed; that was observed in TMSY in this April. |

| * Modify MEDM screen * Add DC PD and so on. * Cable Dsub 15pin for TMS-VIS OpLev. * Return plastic boxes. * Install rails in digital rack. * They may be necessary under LVDT distributor, geophone distributor, and WHT board. * Nagano is not sure it is necessary under HP coil driver. * Measure the length between BRT lens3 and GLNS1 == Wanted! == * Black tubes attachable to the DC-PDs or seetabale in front of the DC-QPDs for light shielding. * Screws to screw Dsub 15pin connectors to QPD amplifiers * Already screwed for IR and GR QPDs. Not yet for TMSX VIS oplev. * Nice way to turn off the ceiling LED light * Covers for cables running on the floor * Shield box against environmental light * Wind shielding... (it would be somewhat difficult as two beams are running in the different directions from the viewport window) |

Transporting some optics to Y-end
- We have transported TMSY optics from Xend to Yend. Four cardboard boxes from Thorlabs and Japan Laser, and optics stored in the desiccator.
- Oplev-QPD for TMSX-VIS and are left at TMSX.
- At TMSY, we have replaced a periscope for IR. It was temporarily using POP/POS-style periscope, but we replaced it to a real Nagano-style peroscope for. The periscope is placed at the preliminary position. The mirrors on POP/POS-style periscope were reused for the Nagano-style periscope.
- POP/POS-style periscope assembly
- 2inch mirror mount: KM200 x2
- Post and base: P250/M, PB4/M
- Post fork: PF175
- Post mounting clamp: C1511/M x2
- Nagano-style periscope assembly
- 2inch mirror mount: SN200-F2K, SN200-F2K-LH (Newport)
- Post and base: P300/M, PB2/M
- Post mounting clamp: C1511/M x2
- Spacer: RS3M x2
- POP/POS-style periscope assembly
- The POP/POS-style periscope was brought to the POS table.
