LEIR & ITE BPMs COMMISSIONING STEPS
2
1. LEIR BMPs: a. The LEIR orbit will be available at start up and both electronics will be present, the old and the new one. b. Turn-by-turn acquisition will come later in the year. c. First turn: the problem to be solved here, once point b is ready, is how to trigger the first turn. 2. 2 new BPMs being installed in ITE (#1 & #2)
3
The coming commissioning can be divided in 3 phases once the installation is finished (electronics in case 1 and everything in case 2) Individual system test: a Responsibility: BI. b Actions: integration in FESA/Control system, verification of the acquisition/publication mechanisms. Integration in the logging system (though this could be OP responsibility, I do not know). BPM Calibration. Dry runs: a Responsibility: OP/BI b At this point if the BPMs are integrated already in YASP this could be of great help. c Re-verification of the acquisition/publication/logging/YASP Beam commissioning: b Polarity issues c Orbit stability: are there residual orbit drifts due to e.g. temperature effects, ripple of correctors power supplies, or other effects d Commission the LEIR orbit e Commission the steering of the TL with the two new BPMs. When Turn-by-turn firmware will be ready will have to go again through the three phases. However, in the mean time we could already work on the software for Turn-by-turn and how to solve the triggering issue for the first turn.
