1. LHC Position Data
The presentation follow-up from:
Reminder for the algorithm used in the order it is applied:
1) Ambient temperature (linear)
=> Offset
2) Electronics (non-linear) as function of beam (bunch) intensity (fixed and dynamic parameters)
=> Gain and offset
3) BPM type and aperture (non-linear geometrical factor)
=> Gain

2. LS1 objectives Further work on understanding the BPMs (simulations)
Updated parameters 1) now published in EDMS
Temperature controlled racks
Offset issue should be decreased
Port software to Linux (increased memory available and network performance)
On-going (well advanced)
Further dry-runs to be planned
Performance with large buffer-sizes to be tested (also for concentrators) (reminder: max = 1.3Gbytes/beam)
