This is a list of issues I have with NOvA era RR and MI injection closure programs. It is a reminder also for myself. I hope we can have as much done so at the start-up we just need to worry about beam calibrations(in reality there are always things unexpected).

1. BO->NR: NR BPM system and TBT data - If the BPM hardware/software and the 
6
Control Department utility are going to be copies of or similar to the existing MI BPM system this part will be simpler. With BO->MI line, the sequences are 1) wait on right event and make sure the BPM system have the data ready(by x26) 2) call a utility routine to get TBT data with right state, BPM, batch.

2. BO->NR: Two or more trims(orthogonal in phase) per plane and their power supply devices.

3. NR->MI: use MI BPM as TBT source the same way as the line BO->MI, with similar data quality expectation?  Years back when we worried about stability of the Lab-view BLT we were not encouraged by tbt quality of normal BPM. But that was for small Pbar beam.

4. Are there additional lines besides BO->NR and NR->MI?
