    keyword=IOC crash, heater problem

    IOC crash at 7:15. Rebooted. When controls came back, cannot adjust the idle heater power on loop 1 above ca. 480 W. Opening the JT valve just results in the target temperature dropping, not an increase in heater power. It's possible that not all control parameters are set correctly, but everything we have information on appears to be set as it should. We decide to run with a max power of 480W and a max beam current of 80 uA for now until a target expert looks at the system.
