Cavity 1 looks like it gets some strangeness on its forward and reflected power that builds in amplitude over ~12-18 hours, then settles back down. Two instances shown in figs 1 and 2, both shown together in fig 3. Cavity 2 doesn't seem to suffer the same problem. I haven't seen any changes in beam behavior that might correlate, but I also haven't given it an extensive look yet.

Per guidance, turned amps off and back on. It took two tries on amp 1 and only one try on amp 2; RF recovered without incident and forward power appears to be stabilizing.
