32. What has been learnt from LS1

Katy Foraz

9/25/14, 2:20 PM

The Long Shutdown 1, which started in February 2013, is almost finished. A huge number of activities have been performed, and the machine is now being cooled-down and power tested. As part of the preparation for Long Shutdown 2, the talk will review the process of the coordination of LS1 from the preparatory phase to the testing phase. The preparatory phase is a very important process: an...

33. Safety & Radiation Aspects

Doris Forkel-Wirth

9/25/14, 2:50 PM

CERN’s Radiation Protection Rules and Regulations are based on European Directives and Basic Safety Standards, as well as on the national radiation protection legislations of the two Host States France and Switzerland. These reference rules and best practices continuously develop, with a tendency towards increasing restrictions whilst activities in radiation areas at CERN strongly intensify in...

34. LIU Planned Activities

Julie Coupard

9/25/14, 3:15 PM

The baseline LIU installation activities corresponding to both ion and proton upgrades will be described for the whole injector chain. The additional possible installation activities linked to the pending options on which decision will be made during 2015 will also be reviewed. It will be examined whether any of these activities can be anticipated to earlier shutdowns or postponed beyond LS2,...

35. HL-LHC Planned Activities - Accelerator

Isabel Bejar Alonso

9/25/14, 4:15 PM

This presentation will be focused on the activities planned by HL-LHC during the period pre LS2 and during LS2 with their milestones, deliverables and key constrains. It will also give an overview of the construction and test facilities that will have to be upgraded or built to allow the construction and test of the future components of HL-LHC.

36. LHC Experiments Upgrade and Maintenance

Werner Riegler

9/25/14, 4:45 PM

The LHC experiments have planned significant maintenance and upgrade efforts for LS2. ALICE and LHCb will implement major upgrades with important changes to the entire apparatus, while ATLAS and CMS will perform their major detector upgrades only during LS3. However, the overall scale of the LS2 operations is quite similar for all experiments. The presentation will review the LS2 plans of the...

37. LHC @ LS2

Marzia Bernardini

9/25/14, 5:15 PM

After a second period of operation of more than 3 years, the accelerator complex will be stopped for about 18 months. The main purpose of the Long Shutdown 2 (LS2) is the LHC injectors upgrade (LIU). Nevertheless LHC will profit from this period to perform the full maintenance of all the equipment, to consolidate part of the machine and to anticipate activities, where possible, of the LHC High...
