We asked Kamiizumi-san to replace the broken op-amp on the DCPD preamp,
and Kamiizumi-san and Shimode-san fixed it for us by the end of the day (thanks!).
We checked if the other preamp works fine by adding a signal from an oscillator
and it was successful.
We moved out a POS table with Hayakawa-san and others using Bishamon.
The table is now on the east side of the OMC outside the clean room (wrapped).
The picomotor cable was delivered so we connected contacts and the cable
is ready to be installed in the chamber.
We tried to add one more contact on the DCPD preamp input cable inside the
chamber so that we could drive Zswitch but it turned out the contact from
accuglass is a bit thicker than the one for cosmo-tech. We ordered a new
contact from cosmo-tech and it will be delivered this friday.
