Session 2a: Impact of accelerator instrumentation on vdM calibrations

• Georges Trad (CERN)

7. LHC beam current measurement: performance and issues in Run 2, prospects for Run 3

Marcus Palm (University of London (GB))

04/06/2019, 14:00

Discuss the
- BCT, FBCT, LDM, instruments performance in measuring the ghosts and satellites
- use of BQM as current monitor for bunch by bunch fractions?
- prospects for Run 3?

8. LHCb ghost-charge measurement & FBCT corrections

9. LHC beam orbit & position measurement

Marek Gasior (CERN)

04/06/2019, 14:40

Discuss the
- BPMs, DOROS instrument performance & issues in determining the beam orbit,
- prospects for Run 3?

10. LHC beam orbit and collision position determination & control – performance and issues, prospects for Run 3

Dr Jorg Wenninger (CERN)

Discuss from the operations and machine point of view
- orbit drifts in vdM and physics fills,
- scan and x-ing angle precision
- what would be different in Run 3?

11. Impact of orbit drifts & magnetic-hysteresis effects on vdM & length-scale calibrations

Witold Kozanecki (University of Manchester (GB))
