Following up on Marcy's email thread.
At the risk of adding noise to the discussion, I believe we have two independent problems.
1. Slow, sinusoidal beam motion with a period of about 25 to 30 minutes. This motion is entirely horizontal and is present at 1I07 but not at 1I05, meaning it originates in one of the following, in descending order of likelihood in my opinion:
a. HWien
b. MBH1I05H
c. MQW1I05
d. MQW1I06
e. Prebuncher
The readbacks from all these elements (liveplotted to avoid deadband) show nothing.
Can there be a slowly varying external field?
