ECFA HL-LHC Workshop 2014Aix-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-Bains http://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 3rd Joint 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

Preparatory Group Membership

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/systemIf 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

Conclusion (1 talk 30‘)

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

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
