Test on Bare Local Support with active cooling system (July 8th 2020):
Picture | Description | ||||||
---|---|---|---|---|---|---|---|
Local Support at the start of the cooling process (2:43 pm, 7/8/20). The minimum temperature read in the local support is about -3 ºC. To understand the structure, please compare the IR camera picture with the picture below from the visible light camera. | |||||||

Status of IR camera readout and offline analysis (as of May 21st 2020):
...
An alternative read-out system with built in calibration functions to read the camera directly from a computer and get rid of the phone is being developed in parallel.
Status of RTD readout (as of May 21st 2020):
...
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):

Status of equipment for P19-0 testing (as of May 21st 2020):
Item | Power Supplies | RTDs | RTD NIM modules | IR Cameras | Phone | Heaters | Gantries |
---|---|---|---|---|---|---|---|
Quantity | 4 |
, more precisely 1 (60V, 3.3 A) and 3 (40V, 5 A). |
~50 | 5 three-wire plus 1 four-wire | 2 | 1 | Enough wired single and quad heaters to load a ring and a stave (see excel document below for details). | 2 |
Notes |
1 60V (3.3 amp) and 3 40V (5 amp).
The preferred (low current) configuration is 4 powering lines: 2 lines on each side of the ring, 1 for the quad and 1 for the single. The ideal would be to get 2 identical power supplies for the quads and 2 for the singles, while right now we have one of a type and 3 of another. | 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) | More available (to be wired) |
