<div style="direction: ltr;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);"> How is it going with its preparation? I have read your exchanges with Raphael but here are two points to have dates in mind:</span></div>
<div style="direction: ltr;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);"> - the HDC will arrive at JLab in March Monday 18. So contrary to what I was telling you, not this month February which was our initial
aim</span></div>
<div style="direction: ltr;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);"> - the slight delay means I can not come with it, and will come first half of April, it is at this time that I would like to test the
detector with the gas if available.</span></div>
<div style="direction: ltr;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);"><br>
</span></div>
<div style="direction: ltr;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);"> As we discussed, I ask around how to add water. The idea is basically to split the gas in two lines, one dry, one wet and modify the
flow to modify the ppm of water.</span></div>
<div style="direction: ltr;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);"> The wet line is then sent to bubbler with water. The quantity of water is monitored at different points in the line before and after
the detector.</span></div>
<div style="direction: ltr;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);"> The email from the specialist is after my mail.</span></div>
<div style="direction: ltr;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);"> In terms of timing: this solution does not need to be ready when we are in the EEL building as it will be used only if the detector
has troubles due to ageing.</span></div>
<div style="direction: ltr;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);"> I know, it is never pleasant to modify or add functionnality to a system being installed but do you think that such solution could
be added?</span></div>

<p style="direction: ltr; margin: 0px;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">- the flow can be divided using with manual or automated valves</span></p>
<p style="direction: ltr; margin: 0px;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">- a water concentration analyser can be added to monitor or to control the valves splitting the flow</span></p>

We may be able to use premix, or we could mix our own gas. If the flow rate is low, premix is more accurate and more reliable. We can also order different ratios of gas for the premix, depending on what you need. If the flow is high and requires frequent
premix bottle changes, then we can use a mixing system.</span></p>

to maintain the correct pressure in the drift chamber. The Hall temperature is consistent. If we mix the gas on the gas pad, the gas will be cold, but travel over 100 feet in the Hall before it gets to the drift chamber and should reach Hall temperature
by then. We can calculate the gas temperature near the drift chamber to see if it will reach Hall temperature. If it is still too cold, we can install a radiator to warm up the gas.</span></p>

I do not know any such person who checks everyones setup for eddy currents. Each group does it for their setup. You should find an engineer who can calculate the design and asses the effect of solenoid quench on the detector.I am cc-ing Bob on this email as
he may know more how other detector did this.<br>

Dear Stepan,<br>
<br>
During the ERR we had questions about the EDDY current. So far we were just planning to be careful about it without doing any specific simulations.<br>
Our design is not yet finalized but we would like to start the discussions about this now or in January if possible.<br>
What is the usual procedure ? Is there someone at JLab checking every setup that will be placed in the magnet? If yes, we would be happy to discuss with this person the best choice of material, the dimension limit etc. to avoid drawing something that eventually
would not be accepted and also simply discuss with an expert.<br>
<br>
Have a nice day,<br>
