Here are the latest upgrades to the P&I diagram. None of the
filters have been installed yet. The N2 sketch includes plans to
run up to four dewars through a manifold (four would only be
needed during Christmas Break) . Please feel free to let me know
of any changes needed. Thanks for expediting the matter.

What is the status of the RICH alterations?
<br>
<br>
As a reminder, alterations should not be energized until I have
signed things off. I could still use the corrected P&IDs.

Thanks,

For the compressed air P&ID:
<br>
<br>
Please eliminate the "TO RICH #1 & #2 ATM" notes.
<br>
<br>
Add two dashed boxes to show boundary of RICH detectors and
add the manifolds.
<br>
<br>
Add isolation valves where needed.
<br>
<br>
Move the pressure system boundary to encompass the manifolds.
<br>
<br>
<br>
For the N2 P&ID:
<br>
Add the isolation valve.

I have attached two diagrams with the changes which we need
to make
<br>
today. The N2 change is the most critical, due to the
installation of
<br>
the Aerogel. I will contact you this morning to discuss any
issues you
<br>
may have with the change.
<br>
<br>
Thanks,

We are preparing to start continuous N2 flow to the RICH.
Once the
<br>
Aerogel is installed the purge must be continuous to avoid
the
<br>
absorption of moisture. Before this happens we need to
install an oil
<br>
coalescing filter before the N2 supply valve to the panel.
We also
<br>
have been requested to install an oil coalescing
hepa-filter on the
<br>
output of the compressor (we have purchased filters for
both
<br>
compressors).
<br>
<br>
We also have been requested to monitor the moisture
content of the
<br>
compressed air, to do this we will use the same instrument
used on
<br>
the DC gas. George is looking into the best installation
location on
<br>
the valve panel for the moisture sensor.
<br>
<br>
Per the Jlab pressure systems program we need to run this
through you
<br>
(as the system owner) and get all the approvals before
modifying the
<br>
approved system. We should have an updated P&I ready
today.
<br>
<br>
thanks,
