Yes, turning on the HV tomorrow evening should work. I will give you a call once we are done working. If you haven't heard from me by 4pm tomorrow, please give me a call because I will be in the MOLLER review and might forget to call you.

Also, can you ask the GEM folks to make a log entry when they are turning the GEMs on and when they have turned them off? This will make it easy for me to understand the state of the GEMs HV when I am reading the HALOG in the morning before beginning work.

<div class="PlainText">Hi Jessie,<br>
<br>
The GEM people wanted to know if they could switch on their HV at least<br>
for one night during the week to conduct some tests. It will probably not<br>
be tonight (they have some overhead time to flush Ar-CO2 instead of N2),<br>
but I wondered if that could happen tomorrow evening for instance.<br>
<br>
So perhaps we could do the following:<br>
1) we first agree to do it e.g. tomorrow evening after you and your team<br>
is done working in the hall<br>
2) When tomorrow evening you and your team are done working in the hall<br>
for the day, you call me, so I can call the GEM experts so they can get<br>
started on the work they want to do.<br>
3) we make sure that by the time you go back to the hall the day after,<br>
the HVs are turned off so you and your team can resume work in the hall.<br>
<br>
If tomorrow evening/night cannot work for a reason or another, please let<br>
me know what other day can be good.<br>
<br>
Also, I am very aware that the amount of work in the hall is enormous, but<br>
we want to get a sense of how likely it is that you will be able to change<br>
the J2 GEM layer<br>
<br>
Best,<br>
Eric<br>
