[acg] Machine instability and oscillations

[Gary Croke]

Hi All,

Ops have been trying to track down the source of two different periodic instabilities in the machine.  They believe they've tracked a 13 second one to 0L03 cavity 8.  However there seems to also be an 80 second oscillation that they are still hunting.

If you can think of anything that could be the source of this, either in software or the systems you are familiar with, please bring it forward.

Thank you,

Gary
