Monday, August 27, 2012, 15:21, Aurelia Laxdal, , , , , , , In progress, Xantrex PS 10-600 for TSH:TGHT is not working
|
When turned ON it was not going higher than 3.6A (EPICS/front panel). Kazuya checked the connections at the back and also the EPICS/PLC/PS input/output signals. He compared these values with the similar once of the TSH:TBHT PS (which is also a Xantrex PS 10-600). E-Fault 6275
It turned out to be the connections on the top of the ion source box: the target heater was not connected and the power supply was not seeing the load. Tomorrow we'll check all the top connections, with the corresponding power supplies. |

Wednesday, August 29, 2012, 11:34, Aurelia Laxdal, , HP-FEBIAD, ITE, TM4, , , In progress, NiO#1 heating startup & few checks
|
Friedhelm checked the voltage across R4 from ISK4563D-rev2.pdf. It shows 50 kOhms with the power supplies off and everything connected according to the drawing. With the Anode PS On and set at 20V, we could see the same readback on EPICS and on the meter.
Then started the heater ramping: auto ramp 2A/min.
We'd be watching the vacuum carefully during this process. Also the setup is such that:
- the target and tube heaters are only incremented if the vacuum is less than 5e-6Torr
- and if the vacuum exceeds 2e-5Torr the last increment of the target and tube heater is backed off.
Pierre asked for the 2e-5Torr limit to be changed to 8e-6Torr.
Anders asked to stop the heating at 500A to take a temperature measurement.
Raising the target heater from 500A to 580A.

The source was used yesterday for operator training.
Today, I found the source off: the ISAC PLC Status was stopped. Kazuya re-started the PLC. I will re-start the source. |
