[WAB cooling] Some electric connection

Simon, Hasegwa, Miyo, T. Yamamoto, Akutsu, with helps by Miyamoto (pin connection):

  • A thermometer in the cryostat was connected to a cryocon outside of the clean booth; the signal has been online.
  • An oplev was setup and a calbe from the QPD circuit was connected to a board in the digital rack; the signal has been online.; before that, an oplev viewport window was installed in the -X-Y direction.

Miyamoto-kun kindly showed us how to connect a burndy pin and an electric wire (even AWG36), and was helpful to make a thermometer online.

Note that the oplev pylons still stand on the floor temporarlly; need to be fixed tightly later.

Details here.

And the beam power of the oplev was too large; ND filtes are required.
