keyword=Close JT valve a bit
MCC predicts that we won't be getting beam this shift (although things might be looking up). The CHL flow was averaging around 22.8 g/s, but was rising at times. No need for a close call if there is no beam, so I closed the JT valve a few steps (went from 66 down to 61). The step size was 1%, but it seems to be closing in steps of 2%. Now CHL flow is below 20 g/s. JT valve should be re-opened if we return to 40uA.
