ECFA HL-LHC Workshop 2014 Aix-les- Bains -II 2013 Workshops

1. ECFA HL-LHC Workshop 2014 Aix-les-Bains-II 2013 Workshops The European strategy set the overall framework adopted by CERN Council May 2013, at http://council.web.cern.ch/council/en/EuropeanStrategy/esc-e-106.pdf. See also “Snowmass on the Mississippi” reports at http://www.snowmass2013.org/tiki-index.php All 4 experiments, the accelerator and the theory community were represented at the October 2013 ECFA HL-LHC Experiments Workshop at Aix-les-Bainshttp://indico.cern.ch/conferenceDisplay.py?confId=252045 The report from this to ECFA can be found at https://cds.cern.ch/record/1631032 which focusses on the detector requirements and physics reach with 3000fb-1 See also the Review of LHC and Injector Upgrade Plans Workshop on 29th October at Archamps (https://indico.cern.ch/conferenceDisplay.py?ovw=True&confId=260492) And the 3rdJoint HiLumi LHC_LARP Annual Workshop” on 11th November at Daresbury (https://indico.cern.ch/conferenceDisplay.py?ovw=True&confId=257368) The next in the ECFA HL-LHC workshop is planned for 21st -23rd October 2014 1

5. How to Organise Next Time? • Stay with all plenary format to keep the communication flow • Should not need as much introduction • Should involve theory and accelerator communities much more closely with more talks in these areas • Try to build on synergies identified/developed since last time and emphasise common approach • Therefore could propose to organise sessions now more by R&D area than sub-detector/system If so, need to keep clear relationship with HL-LHC detector needs (not too generic) Should find a way of preparing material that is as inclusive as possible (ie open mini-workshops) • Can be more flexible and include a few invited talks on topics not included in sessions

6. How to Organise Next Time?

7. How to Organise Next Time? • We propose we could start from the previous preparatory group structure, at least to see if the previous chairs are still willing to help • However, the session topics do not map so well to the previous groups and in some cases we should consider to merge the activities • If we move towards a few individuals per topic who can help organise each session, we should find a way to ensure they engage fully with the relevant players in all four LHC experiments and do so in as inclusive a way as possible • The audience composition might be broader if we can emphasise more the links with the accelerator and theory communities • Probably the concluding session was too long last time and the idea of a discussion in this context is quite difficult to organise

8. How to Organise Next Time? • We need to get the venue agreed, the cost settled, the preparatory structures put in place and create web pages and publicity • We have a pre-booking at Aix-les-Bains for Oct. 21 to 23 • Network issues should be solved with installation of new system • We have offers for the congress centers, breaks and lunches and a left over of ∼ 5000CHF from 2013 • Assuming 200 participants, same fees as in 2013 of 190/265 CHF w/wo dinner should allow to have a welcome drink and an improved conference dinner possibly at the lake
