Sebastian Raeder | | | | | | | | 9 PIN connector | A Sub D 9 Pin connector on a HV insulator was installed on Port Q of the target box at the teststand. The insulator is leak tested and OK, vacuum is below 2E-7 T
The feed through is connected (1to1) to the upper 9 Pin connector of the target tray. Since the existing upper 9 Pin connector was damaged from a previous FEBIAD test, this connector was replaced. For wiring 4 twisted pair Capton insulated and shielded wires (identical to ITE and TM4) of about 50cm length are used.

1to1 connection for pins 1,2,4-9
Pin 3 is NOT CONNCTED
The pin pairs 1&2, 4&5, 6&7, 8&9 each use a line of twisted pairs

Connection to the HV added. The wires end in the HV cage on a screw terminal with labels 1--12. The numbers 1,2,4-9 are used in corresponding notation to the sketch above. Since 3 is not connected at all this terminal is used for grounding the wire shielding.
As cable 2 Capton isolated pairs of wire (1&2, 4&5) and two "normal" pairs for thermocouple (6&7, 8&9) reading are used. So all connections have shielded twisted pair cable, while (6&7, 8&9)change the cable type at the 9Pin connector |

Aurelia Laxdal | Test-SiC | HP-FEBIAD | | | | | | E-Fault#6389 re-directed to PS | Evgeniy and Kazuya investigated the problem with TSH:TGHT readbacks and they came to the conclusion that the PS is faulty, and the PLC reads correctly the signal sent by the PS. Kazuya is redirecting the E-Fault from Controls to PS.
Ray Dube estimated few weeks (4-6) to send the PS offsite for repairs. This needs to be scheduled. For the time being, one can use the Test Stand with the PS setpoints, displayed on its front panel, as a reference. |

Aurelia Laxdal | Test-SiC | HP-FEBIAD | | | | | | Preparations for E-Fault#6389 investigations | Prepared the Test Stand for Controls to investigate E-Fault#6389.
Evgeniy increased the current limit on the power supply TSH:TGHT from 2 rotations to 7 rotations, after talking to Ray Dube.
I turned on the HV at 30kV and started the Auto-ramping. |
