History
#1 Updated by John Diamond about 3 years ago
- Status changed from Assigned to Rejected
According to Bill, B38 and B40 do not use these devices. Rejecting the issues for now until someone asks for it.

- Status changed from Rejected to Assigned
Turns out this device is needed according to Bill. Here's how he defines it in an e-mail from 11/2/2017 -
The smooth orbit devices are B:xxCORP which average 8 orbits at turn numbers 180, 452, 912, 1386, 1879, 2393, 4045, 8875, 10118, 13872, 17640, 19526. The setting defines the event to take the data on and the number of pulses(event index) after a 12 to identify the pulse (I don’t remember whether the index starts with 0 or 1)

- % Done changed from 0 to 10
This will be referred to as a "Smooth Orbit" reading. Smooth orbit parameters (breakpoints, cycle event and cycle index) will be stored in the shared memory region (SmoothOrbitParameters) where they can be accessed by BoosterCrateACNET and BoosterStateMachine. The breakpoints can be passed to DAQSystem as a vector of turn numbers with the number of turns to average.

- Status changed from Assigned to Work in progress
- % Done changed from 10 to 90
- Z:BTCORP
I noticed that the smooth orbit devices for the existing booster bpm system have control and status properties. E-mailed Bill to ask him how these work.
