<p>Hi Jason<br>
</p>
Thank you very much. This morning, George was working on it and I
hope the blanket is just slow to warm up and not failing.<br>
George would like to have a thermostat installed to make sure heat
tapes will not overheat the flowmeters and consequently break them.
I agree that it would be safer since we are kind of blind in
regulating the power of the heat tape.<br>
<br>
Volker, Walt, would it be possible to have it done as soon as
possible? If everything goes well for the accelerator, tomorrow
evening we have beam sent in the Hall. But I cannot use the mixing
system yet. No real test have been done with it. These tests include
checks that the mixing system works well, but also tuning the HV
setting depending on the quality of the mixture. (depend strongly on
the mixture... this is part of the "calibration" of micromegas
detectors).<br>
<br>
If we have everything we need to do the job, please try to have it
done today. I apologize for the rush but this mixing system was
supposed to be ready a long time ago and not the day prior
engineering run.<br>
<br>
Thank you,<br>
<br>
Kind regards,<br>
<br>
Maxime <br>

When do you think the electrician will add the plug to the
blanket and for<br>
