[Dsg-halla_gem] Inline GEM filters

[George Jacobs]

Hi Ching Him,

Nice to have some good news in the morning. Yes, I will continue the installation and configure the filters as you request. I will be going down to the hall in about 45 min to continue work on the SBS rack.

Cheers,
George

Hi George

With the 47 filters(8 from BB and 39 Holly purchased), could you install them on the on the first 47 channel on the rack? This includes the 8 channels from BB and channels 9 to 47 on SBS?

I believe we will only be using 46 channels in the next experiment.

Thank you
Ching Him

Hi All,

This is an update.


  *
We are short 21 filters
  *
16 channels completed
  *
Total of 35 filters found only, this includes the 8 on the old BB rack.

I will continue this installation tomorrow, but what about the 21 channels without filters?

Cheers,
George

Hi George

I have disconnected the gas lines from the GEMs. Please let us know when you are done.

Thank you
Ching Him

Hi George,

In principle, I think it is not a problem tomorrow, but please coordinate with Ching Him or Asar (in cc).

Thanks,
Holly

Hi Holly,

I can install the filter fittings in the hall.

In order to install the shelves and filters, gas lines will need to be disconnected and flow will be interrupted during this process.  Will that be a problem? I was thinking about performing this work tomorrow afternoon, Thursday 8/8. Does that work for you?

Cheers,
George

The GEM filters are in a very large box in Hall A near the gas distribution panel. Do you want to take them out of the Hall?

Hi Holly,

The fittings have arrived for the GEM filters. Could I pick them up or can you have someone drop them off?

Cheers,
George
