Wednesday, October 30, 2019, 14:49: John C. changed the polarity of the anode power supply to negative, and Fernando M. rewired the cabling on the service cap.

Just as side note, I think the PS was in negative mode since the quoted entry from October 30 2019. Given that the SiC/FEBIAD was supposed to run in cathode mode, the test stand was rewired to this. The only rewiring after this was for the P2N. |
