[Takahashi, Ishizaki, Sato, Shindo, Miyo, Okutomi]

Assembly of the Dummy Payload (DP) and the Bottom Filter (BF) installed into the chamber

• We should wait for the protection net back to do remaining works on the installed stages
• Remaining works:
  • Cabling of the release sensors
• Takahashi-san did deburring on the hole of the wrong wire receptacle and now the maraging wire fits on it
  • He reported it's not a design problem, but some burrs which remain on the edge disturbed the wire
  • This receptacle for the keystone of the BF has different shape than other new receptacles for Standard Filters
    • It means that other new receptacles are free from this problem
    • I note that the same parts for other Type-A should be care about that however they are nor procured yet
• Cap screws on the EQ-stop which support the BF from its bottom are used in correct direction while ones for the DP are not (as reported in klog #2452)
  • Instead of using it upside down, we added nuts and gain height
  • The height is adjusted as 50 mm to let all weight of the BF not to load on the release sensor but on these screws
