3rd version of the mass marker target has been installed. This one is further back on the heat shield, and has a longer ceramic piece attached. There are three thermocouples as follows:

Monday, March 21, 2022, 13:55 : Roughing down.

Monday, March 21, 2022, 16:45 : Turbos have been on for a few hours. Starting water.

Monday, March 21, 2022, 17:20 : Only TC1 has to be tested with heating and maybe swapped if it is the wrong way around. Otherwise ready to go.

Thursday, March 24, 2022, 10:51 : Ramping up heaters to test thermocouples.

AS:

Monday, April 04, 2022, 09:10: Power locked out. IG1 & Turbo pumps off. HV top cage removed.

Swapped the old 9pin connectors out and replaced with 2 5-pin connectors, same as on the modules.

See attached for current pin out diagram. Many of the wires are too short to reach the bottom sockets, so wires 2, 8, 9 are not connected in the connector. 4 spots are empty on connector 2 (right).  (6, 7) and (4, 5) are twisted pairs. Unused wires are tapped up out of the way, but we should improve this, the tape may come loose due to heat and then the wires could present an HV risk. (Update: added some wire to hold them in place. Slightly better...)

Need to either extend the wires, or put in new ones. All wires are grounded on the rack.

In addition, there are two screws in each connector which are floating right now. Need to make a connection for them but should be ok if we dont go to really high voltages.

Wiring which was changed to run the mass marker tests has been reverted:

• anode bias cable connected to "B"
• tube negative attached to HV common through "B" to "F" connection

Ready for cathode biased FEBIAD operation.

 Gas system switched on manually to use Ar & calibrated leak.

A web-app for systematic FEBIAD parametrizations has been develop and  now includes the ISAC Test Stand (ITS) :

https://beta.hla.triumf.ca/degaussing/FEBIAD-scan/

Upon landing in the web-app the ITS will be selected by default as well as the TMS:FC6:SCALECUR faraday cup, which corresponds the last cup of the ITS beamline.

To run a similar scan but on the total source current (FC0) the field has to change from TMS:FC6:SCALECUR to TMS:FC0:SCALECUR.

Each measurement will create a unique id (measurement_id), and the data can be retrieved from

https://beta.hla.triumf.ca/jaya/data/get/measure_id

Plot and analysis routines for the data generated by the FEBIAD-scan can be found in 

https://jupyter.triumf.ca/hub/login

for which you need a TRCOMP account. The routines are located in the group folder 

/group/ionsrc/fernando
