Japanese Sites for ILC

- LCC Directorate official site visit next week.


European activities

• BF has visited European funding agencies – Italy, Germany, UK – to discuss ILC and involvement over the next few years.

• BF & E. Elsen visited Brussels on 13.9 to brief them on ILC status and enquire about possible H2020 funding. Very useful meeting.

• ILC was explicit item on Agenda, given priority even though R-JS was 1 hour delayed. He and colleagues had been briefed after 13.9.


• BF attended annual CERN/EU meeting at CERN on 25.9. Attended by R-J Smit, DG of Directorate Research at EC.

• BF described current situation and R-JS responded at length. Discussion was animated. EC is clearly interested in ILC and wishes to follow closely. Agreement to set up “group of 4” – BF, SS + 2 from DGXII – to maintain close contact over ILC. Meeting suggested 12.13 – awaiting DGXII response.

European activities

• N. Walker et al. have drawn up draft indication of how Europe could get involved in site-specific work for next few years prior to project approval.


European activities• Notional breakdown of a request to EU


• Under active discussion in LCC. Meeting for further development in January in DESY.

European capabilities

Three main strong points:

– ILC participation (back to Tesla)

– XFEL and industrial base linked to it

– CLIC and combined CLIC/ILC activities

Make use of these ….

“Obvious model” to consider:

• Keep capabilities to build and deliver cryomodules (natural lead DESY and CEA, but also INFN expertise)

• Focus on a couple of other system where Europe have expertise, scientific/technical capabilities

(BDS system linked to participation in ATF, possibly damping rings, … )

BDS sticks out due to significant communities in UK, Spain, France, CERN, …

Next years – possibly related to EU supported activities:

• Develop these two branches, with EU support if possible

• Would naturally form two main technical development branches where most of the European ILC

community could participate, with European industry partners

• Put together a modest team, distributed across mains labs with limited material budget, focusing on the key areas

above (would also put in place a European structure, and support key existing activities linked to cryomodules and

BDS/ATF in particular)

2014-2017(18): Design finalisation, technical designs & site specific design

European leadership but also clear interest from China and US

XFEL European leadership

Other talks in this session

European project(s) to make coherent contribution to well defined and visible Japan lead but international design team – could invoke EU support

2017-2020: Pre-series

For potential deliverables

At end of XFEL

For potential deliverables

… Outside scope of current discussion but capabilities in phase above (labs, industry)

2018-2028: Construction

Part could be delivered by Europe but likely other major possibilities

Fraction of cryomodules

Main parts could be delivered by Europe(room for others as well)

…. Outside scope of current discussion

Summary• We have lots of expertise in Europe and even some substantial

effort devoted to ILC. There is much more effort currently devoted to CLIC, some of which is relevant for ILC.


• Currently there is insufficient funds and people available to do the jobs that should be done now – site-specific design, optimising production models, etc. .

• ILC is visible to EC and there is interest. H2020 is a possible source of effort to leverage European expertise.

• Much to do to hammer out a coherent accelerator activity that optimises European interests and expertise and to find the necessary matching effort/funds.

• Strategically, how do we play this? Separate machine/detector bids at separate times? A subset of detector/accelerator topics labelled as e.g. “site specific”? A grand all-encompassing proposal? All needs to be discussed.

Invitation

• I mentioned a meeting in January to discuss the future R&D for the machine. Thisis in conjunction with aSymposium organised byDESY on January 13th to celebrate my continued journey towards senility:


• You are all cordially

invited!
