<p>Dear Jack, <br>
</p>
<p>The Marc Mullen from DSG group has just set up the SBS gas system
prototype for us in the TEDF highbay area to try it out on the UVa
GEM layer we just recently installed in Bigbite frame. <br>
</p>
<p>We would like to notify to that we are now ready to connect the
gas supply to the GEM chambers and seek your approval to proceed.
<br>
</p>
<p>We are planning to use a gas cylinder and regulator system
identical to the one we have installed for the commissioning of
the UVa GEM layers in EEL124 clean room and set up for us by
Chuck. This system will be hooked up to the monitoring system
installed by Marc to supply the BB GEM chambers. <br>
</p>
<p><br>
</p>
<p>Please let us know if there is any step we need to take before
going ahead with connecting the system to our chambers. Ideally we
would like to have N2 flowing into the chambers before the xmas
break</p>
<p><br>
</p>
<p>Best regards <br>
</p>
<p>Kondo<br>
</p>

<p>Hi Marc, <br>
</p>
<p>With Chuck help today, we moved the rack in the TEDF
building where the Bigbite frame is located (where our GEM
layer is installed). I don't really know the room number of
the area but maybe Chuck could help me out here<br>
</p>
<p>Chuck also has prepared the gas cylinder to be used for the
test and I believe everything is ready to go. So when you
are available, we can go ahead with the installation.
<br>
</p>
<p>I am not at JLab tomorrow so if you plan to work tomorrow,
Chuck could help also. if not, I will be back at JLab on
Thursday and we can plan accordingly
<br>
</p>
<p>Please let me know <br>
</p>
<p>Best regards <br>
</p>
<p>Kondo<br>

You are correct, the distribution rack is located in EEL
125, near Chuck's gas bottles. They do need to be moved to
the test location in the TEDF.</div>

As far as calibrating, I believe you just want to connect
your old flow meters in-line to check if the flow values
match. You may need to get with Jack (system owner) on
that for those kind of questions.</div>

<p>Hi again Marc, <br>
</p>
<p>Just to clarify a few things once again. So right the
rack is in EEL125 and you want us to move it to TEDF
right?
<br>
</p>
<p>I can see that with Chuck tomorrow then <br>
</p>
<p>Then after that I will have to get in touch with you
for setting the raspberry pi and the associate software.
<br>
</p>
<p>We will have to also set up a mechanism to calibrate
the gas flow meter that you provide with the one we were
using in EEL124 clean room.
<br>
</p>
<p>Can we install temporarily one of our flow meter on the
panel to perform this calibration?
<br>
</p>
<p>Bets regards <br>
</p>
<p>Kondo<br>
</p>
