This cavity has been constantly trying to tune itself for some time. I went in to open-loop tune it but noticed it had walked about 2.6 million steps away from where it was previously over the course of about a week. I tried walking it back all the way to that point and quite a lot further on the other side, but there's been no response from the cavity that might indicate tuner movement. Nothing on the diag screen (fig 3) seems to be amiss either. Is this tuner stuck?

Fig 1 shows that something(?) happened on 5 Feb over about an hour, where the tuner took took over a million steps.

LCW temp is hovering right at the low major alarm limit, causing lots of nuisance alarms. We're in for another cold night, so I'm opening up the alarm limit from 90 to 89.1 (which is just over the lowest temp it dropped to last time ambient temperatures were this low).

Completed Gradient ramp of 1L07. All cavities at their drive highs ( some I cheated a little extra out of). There may be more gradient available in this zone.

Completed the gradient ramp of 1L03. All cavities at their current drive high value with the exception of cavity 4. Cavity 4 is not happy above 11.5. When I try to take it to 12 it trips on CWVF and P1. KMAI is also not happy. That might be where the problem is. When cavity4 goes down it takes 3 with it. As I was posting this entry Cavity 4 made a lie of the last statement. Cavity four tripped on QCHL and P1 (see Figure 4). I'll see if I can keep it on at 11.0.
