[Dsg-mvt] Electricity for heating blanket and heat tape

Hi Jason

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.
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.

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).

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.

Thank you,

Kind regards,

Maxime
