This pages collects links and information on the studies done so far at SLAC for Thermal Testing (and related instrumentation).
Status of IR camera readout and offline analysis (as of May 21st 2020):
to be added
Status of RTD readout (as of May 21st 2020):
5 three-wire RTD modules available (this give a total of 5x8 = 32 channels that can be read in). 3 of these modules were inherited from nEXO, 2 were bought just before the COVID19 shutdown, so they have not yet been tested.
1 four-wire RTD module is also available (this could be used to read in the cooling plant RTDs and get rid of the current Labview based system).
Status of Monitoring (as of May 21st 2020):
The monitoring system developed for the B33 low-temperature freezer (used for thermal-conductive glue storage) can be used to read in and monitor the P19-0 RTD.
One example was tested quickly before the shutdown, it will be fully tested once access to the lab is permitted again.

Status of equipment for P19-0 testing (as of May 21st 2020):
Item | Power Supplies | RTDs | RTD modules | IR Cameras | Phone |
---|---|---|---|---|---|
Quantity | 4 PS available | ~50 | 5 three-wire plus 1 four-wire | 2 | 1 |
Notes | 1 60V (3.3 amp) and 3 40V (5 amp) | ready to be wired appropriately for the test box patch panel (which has connectors HD15 F), will be done by the Electronic lab | the 1 four-wire can be used for the CO2 plant | 1 is (probably) faulty | Samsung S 7 (link) |
