[Dsg-halla_ecal] About heating

[Marc Mcmullen]

Hi Albert,

I am working on the basic monitoring and controls system (for 1 supermodule/heater) in the EEL building. Once I have a good test, I can then expand this for the whole system.

For your test I recommend you contact Bert Manzlak and the area safety warden for the building you will be testing in. They will probably want a HallA-List at the least. Also you should send them  the specification for the heaters.

The 11 prototype heaters DSG procured can be applied to flange 1 of the supermodule. These are designed specifically for use on conductive surfaces (insulated). I can show one of your staff how I applied the heater on to the super module if they have not already done this.

I will keep everyone updated on the controls and monitoring testing.

Hi Marc,

Very soon we will be testing the new heater which you recommend.
I plan to use the new heater only on the front dinner module.
To heat the super modules on the side, use old heather.
Heat the calorimeter around the perimeter also use old heater?
When wrapping an aluminum bar on 3 super modules heater , it will be
normal and safe and secure?
How do you all think about it?

Thank you,
Albert
