[dsg-hallb_rich] RICH-II interlock

[Valery Kubarovsky]

Hi Tyler,

I want to preliminary discuss with you our activity to assemble RICH-II in the cleaning room.
Do you have a plan to design, produce, instal and test interlock for RICH-II?
We are going to assemble everything in the clean room as we did it in 2017. it is difficult to plan during pandemic but preliminary
we want to start assembly in 2021 before summer: mechanics, photomatrix, HV, LV, DAQ etc.

The detector will be equipped as in the Hall-B: HV, LV, DAQ, cooling... I guess that we have to move the compressor from Hall-B to the clean room as well. The new compressor will be installed in the Hall-B and tested in February.

What do you think?

Best regards,
Valery

Subject: [dsg-hallb_rich] Upcoming planned power outage in TEDF/Test Lab should not effect RICH aerogel

Hello,

There is a short, ~30 minute, planned power outage in the TEDF building and Test Lab over the upcoming shutdown (see attached email chain).

This outage should not effect the RICH aerogel dry boxes in the EEL. In the event the outage does turn off power in the EEL, since it is so short, the aerogel should not be too adversely effected and the dry boxes will turn back on and resume drying automatically after power is restored.

We will continue monitoring the dry boxes over the shutdown, as we have throughout the rest of the year to make sure that there are no other issues.


Tyler
