18. TDI

Anton Lechner

16/12/2015, 10:45

TDI limitations and observations up to now (any understanding for vacuum spikes and difference B1, B2) Design of new TDI to be installed during Xmas stop. Any further limitation? Any other limiting element for 288 bunches? Table of parameters for different beams (nominal, BCMS, highlight Run2 ones).

19. ADT

Gerd Kotzian

16/12/2015, 11:10

Improvements applied during LS1: did they fulfill all expectations? Features, present uses of the ADT in different contexts Issues and possible mitigation for 2016 run. Operation with doublets. Are ADT settings clear for operators or need of experts?

20. Instability diagnostics

Tom Levens

16/12/2015, 11:35

Overview of the available diagnostics and functionalities, what was available what was changed/added (ADT, MIM) is it working as expected, foreseen improvements? Status and plans for observation box

21. RF (Beam)

Helga Timko

16/12/2015, 12:00

Improvements applied during LS1: did they fulfil all expectations? Features (parameters used in 2015), issues and possible mitigations for 2016 run.  bunch length reduction observed and its mitigation, longitudinal blowup, maybe something on bunch length stability threshold preparation of RF for higher power. commissioning time? Operation with doublets.

22. Collimation

Gianluca Valentino

16/12/2015, 13:45

Improvements applied during LS1: did they fulfil all expectations? Experience during commissioning and operation: any issues encountered? Possible mitigations for 2016 run. Collimators with BPM: operational experience and orbit stability. Loss maps: optimized procedure and with reduced number of fills.

23. Diagnostics

Enrico Bravin

16/12/2015, 14:10

24. Beam profile measurements

Georges Trad

16/12/2015, 14:35

Improvements applied during LS1: did they fulfill all expectations? Features, issues and possible mitigation for 2016 run. Different measurements: BSRT (and related equipment), interferometry, wire scanners, BGI and BGV

25. Controls - an OP perspective

Kajetan Fuchsberger (CERN)

16/12/2015, 15:00

Evolution from 2012 (see Delphine's Evian talk) Change of machine configuration: can it be improved Migration to FESA 3, really transparent? OP and CO development philosophy OP priorities: are they the same as CO’s?

39. Feedback on Controls from 2015 operation.

Marine Gourber-Pace (CERN)

16/12/2015, 15:25

What worked well, what should to be improved
