2. Operation of a 6 BCHF collider: do we fit the expectation?

Enrico Bravin

13/12/2016, 11:00

The way a complex machinery is operated has a direct impact on the production efficiency. In the case of the large hadron collider, that required huge efforts to design and build, it is of the utmost importance to assure an adequate operation quality.
The exceptional results obtained in 2016 prove that all LHC systems and all teams, including the operation, have reached an excellent maturity...

3. Injection

Wolfgang Bartmann

13/12/2016, 11:20

Losses at injection will be distinguished between the two main loss causes, transverse loss shower from the transfer line collimators and longitudinal loss shower due to satellites which are placed on the kicker field rise and thus improperly kicked into the machine. The dependence of this losses on the different beam types, TL stability and injector performance will be reviewed. A status and...

4. Turnaround and precycle: analysis and improvements

Kajetan Fuchsberger

13/12/2016, 11:40

This talk will present data of turnaround times during the previous run, give some insights in the distribution and try to spot different bottlenecks. The impact of the turnaround time on the optimal fill length will be shown and different contributing factors to the turnaround itself will be discussed. The final goal is to identify areas of improvements and give concrete proposals, based on...

5. Cycle with beam: analysis and improvements

David Nisbet

13/12/2016, 12:00

The 2016 proton beam cycles will be analysed, and proposals for improvements will be made based on the results. Some other suggestions are proposed for reducing the beam cycle time, for example modifying the combined ramp and squeeze, and their effects quantified. The objective is to present a synthesis of quantified potential improvements as a basis for further discussion.

6. Machine reproducibility and evolution of key parameters

Jorg Wenninger

13/12/2016, 12:20

This presentation will review the stability of the main operational parameters: orbit, tune, coupling and chromaticity. The analysis will be based on the LSA settings, measured parameters and real-time trims. The focus will be set on ramp and high energy reproducibility as they are more difficult to assess and correct on a daily basis for certain parameters like chromaticity and coupling. The...
