25. HL-LHC Parameter and Lay-out Baseline

Markus Zerlauth, Paolo Fessia

24/09/2014, 16:00

The baseline parameters of the HL-LHC project will be reviewed and the new high-luminosity insertion region lay-out necessary to reach the project objectives will be described. The presentation will list other modifications that shall be carried out on the present LHC machine in order to reach the ambituous goal of 300 fb-1 delivered luminosity to the ATLAS and CMS experiments per year up to...

26. HL-LHC Magnet Roadmap

Ezio Todesco

24/09/2014, 16:30

We will first give an overview of the 11 T project, giving a summary of the main technical choices made at CERN and in FNAL, test results and future milestones. We then focus on the IR magnets in the HL-LHC. After a short description of the layout, and a catalogue of the numerous magnet types, we will give for each magnet family a summary of the main technical choices. We will then discuss...

27. HL-LHC RF Roadmap

Rama Calaga

24/09/2014, 17:00

In view of the HL-LHC parameters, the present and the foreseen RF systems are reviewed with the primary focus on technological aspects. This paper will describe the preparation and the test program of the SPS beam tests with crab cavities. Some aspects related to the integration of the crab cavity RF system in the LHC and the potential impact of the crab kissing scheme are addressed. The mode...

28. HL-LHC alternative scenarios, parameters and lay-out

Rogelio Tomas Garcia

24/09/2014, 17:30

The HL-LHC parameters assume unexplored regimes for hadron colliders in various aspects of accelerator beam dynamics and technology. This paper reviews the possible alternatives that could potentially improve the HL-LHC baseline performance or lower the risks assumed by the project. The alternatives under consideration range between using flat beams at the IP, compensate the long-range...

29. Collimation and MP Roadmap

Stefano Redaelli

24/09/2014, 18:00

The upgrade of the LHC collimation system represent is part of the HL-LHC baseline and represent an important element for the LHC upgrade. Depending of the performance limitations, we are preparing for a possible staged implementation starting already in the LHC long shutdown 2. In this paper, the main upgrade studies included in the HL baseline are presented. Additional studies for advanced...

30. Down Selection Criteria and MDs Prior to LS3

Gianluigi Arduini

24/09/2014, 18:30

The operation of the LHC and the machine studies conducted during run I have provided important input for the validation of some of the choices that are at the base of the HL-LHC upgrade scenario but it has evidenced also some potential limitations, progress has been done in their understanding but some open points remain that need to be further studied to consolidate the operational scenario...
