<p>Thanks George,</p>
<p><br>
</p>
<p>I am working with Marco Mirazita on the specifications for the
upgraded air system to support both RICH detectors in Hall B.</p>
<p><br>
</p>
<p>Therefore, I will design and install the upgrade, as well as
supply the air and nitrogen systems for the EEL.</p>
<p><br>

<p>Thanks</p>

I assume you want both the original Hall B RICH air cooling
supply P&I and the new EEL air cooling setup P&I for
the clean room. They are both attached.</div>

<p style="margin-top: 0px; margin-bottom: 0px;">Hi
George,</p>
<p style="margin-top: 0px; margin-bottom: 0px;">I am
working on the RICH air system upgrade to run 2
detectors at the same time.</p>
<p style="margin-top: 0px; margin-bottom: 0px;">The
current pressure regulators do not seem to supply
steady pressure to the rotameters. Do you have the
part numbers for the installed regulators?
<br>
</p>
