  3. Magnet the progress • LHC dipolesfeatures 8.3 T in 56 mm (designed for 9.3 peakfield) • LHC IT Quads features 205 T/m in 70 mm with 8 T peak field • HL-LHC • 11 T dipole (designed for 12.3 T peakfield, 60 mm) • New IT Quads features 140 T/m in 150 mm > 12 T operationalfield, designed for 13.5 T).

  11. Implementation plan 2023-25 All WP active, from diagnostics to Machine Protection; Integrationstartedwithvigour as well as QA (workshop today!) Cryo, SC links, Collimators, Diagnostics, etc. starts in LS2 (2018) Proof of main hardware by 2016; Prototypes by 2017 Start construction 2017/18 from IT, CC, othermain hardware IT String test (integration) in 2020; Main Installation 2023-25 Though but – based on LHC experience – feasible LHC has bene a greatexperience… But weshould, do better. What has been waived in LHC, in term of QA, cannotbewaivedtoday. Interchangeability of info, files, etc, must beimproved. This time we design together! Time to make a complete plan: HL Cost & Schedule review to beheld end 2013-begining of 2014. L. Rossi @ Best Practice WRKS 11 June 2014
