    keyword=Q2 and Q3 polarity change

    Had problems changing the polarity on the Right Q2 power supply. Could not get the system to change polarity from the GUI (Epics). Suspect that radiation had scrambled the polarity controls. Cycled power to the Right Q2 and Q3 at the power supply platform in the hall and the system recovered.
