Today's activities

Workers: Akutsu, K. Nagano, Aritomi K. Tanaka, Kita

  • Akutsu cleaned each side of the optical parts to be installed into the chamber (on the BRT) just using ethanol only. So I omitted acetone and First Contact... Anyway, they are

  • Configure the digital models properly.

  • Clean the sides of the optics to be installed into the vacuum chamber. (Ethanol+Acetone wiping with vectra alpha, then First Contact.) See here.

  • 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.
