BSC5 Annulus Ion Pump Controller

(Jordan V., Gerardo M.)

Today at 21:06 utc, we removed BSC5 AIP controller and replace it with a "new" one, this was done in an attempt to solve the oscillation noted on BSC5 readback channel, see attachment.

Unfortunately, after looking at the trend data it appears that the oscillation remains despite the new controller.  We will continue to look into this.
