45. Experiments input for the 2018 run (15' + 5')

Christoph Schwick (CERN)

14/12/2017, 08:30

Abstract:
The contribution will discuss the input of the experiments for the operation of the LHC in 2018. The expectations of the experiments for the pp run are presented together with the constraints (e.g. pile-up, peak luminosity, beam parameters, constraints from forward physics experiments) for effective physics data-taking. Requests for possible special runs will be discussed. The...

46. Recovery & re-qualification (20' + 5')

Markus Zerlauth (CERN)

14/12/2017, 08:50

Abstract:
Re-starting the LHC after the YETS 2017/18 will include the revalidation of Sector 12 after its warm up as well as a repetition of powering and machine checkout tests as a function of the modifications applied to the relevant systems. This contribution will recall the main activities, the implied risks and resulting revalidation needs as well as the resulting planning to allow for an...

47. Heavy Ions in 2018 (20' + 5')

Michaela Schaumann (CERN)

14/12/2017, 09:15

Abstract:
The last month of operation in 2018 will be devoted to Pb-Pb physics and no protons will be available from the injectors. The goal is to build on the techniques for reaching high peak and integrated Pb-Pb luminosity established in the 2015 run. The choices of machine configuration and optics, levelling strategies, beam parameters from the injectors and luminosity estimates are...

48. Instrumentation: What to expect next year (15' + 5')

Tom Levens (CERN)

14/12/2017, 09:40

Abstract:
This talk will present the expectations for the LHC Beam Instrumentation and Transverse Damper (ADT) going into the 2018 run. Planned upgrades during the YETS will be presented and opportunities for future development in order to better exploit the available instrumentation will be discussed.

49. Beam dynamics and levelling scenarios (15' + 5')

Yannis Papaphilippou (CERN)

14/12/2017, 10:30

Abstract:
Luminosity levelling is expected to be a key ingredient to boost the LHC performance and, at the same time, probe future operational scenarios, in view of HL-LHC. In this perspective, the potential and limitations of the different filling schemes from the injectors are compared in terms of their luminosity reach, taking into account emittance evolution, pile-up and heat load limits....

51. Machine configuration and parameters (15'' + 5')

Matteo Solfaroli Camillocci (CERN)

14/12/2017, 10:50

Abstract:
2017 was an excellent year for the LHC. Amazing results were achieved, producing slightly more than 50 fb-1 and demonstrating great flexibility in LHC operation; 2018 will be a very important year as it will mark the end of Run2. A similar result has to be achieved, while start exploring HL-LHC operational configuration. The choice of operational configuration is therefore crucial to...

50. Operational tools from 2017 to 2018 (15' + 5')

Andrea Calia (Ministere des affaires etrangeres et europeennes (FR))

14/12/2017, 11:10

Abstract:
During the 2017 run of the LHC, several applications and tools underwent improvements and new features were added. Next to others, the main focus was on a new system for coupling measurement, based on the ADT AC-Dipole and the luminosity control system, to which e.g. separation- and crossing-angle levelling functionality was added. For 2018, it is foreseen to push these systems even...

52. Guided Discussion (30')
