News:CLIC workshop very successful.

• Next years workshop end February/early March,

partly combining with general LC discussion (ahead

of open ESU meeting in May 2019)

CLEAR and X-boxes doing well – see reports

• CLEAR review late this year, early next year

A 3.5 GeV CLIC type linac (klystron driven) being

discussed in framework of the Physics Beyond Colliders

– see report later

Work in implementation groups (CEIS, Cost & Power,

Main Linac Hardware, Parameters, Novel Acc.) moving

ahead well – you will see some flavours of it today

PiP writing – we will see today where we are

Physics and Detector work progressing well, external

review this week

MTP budgeting 2018-19 not changed, first discussion

of 2020+, see following slides

Key goals (c/p/indu/risk)

3

Modules (drive-beam,

klystron type)

Final modules, from revised

designs to industrial modules

Optimized structure

and RF components

Finalize industrial structures:

increase manufacturability,

brazed, halves, conditioning.

Use/maintain/operate existing

test-stands for testing

Klystrons and

Modulators

Efficiency and costs

improvements, significant

gains possible for efficiency,

industrial cost-models and

optimization

Magnets

Permanent magnets, longit.

variable magnets, industrial

production and cost-

optimisation

Civil engineering,

infrastructure

Detailed site layout and

CE/infrastructure designs

CERNenergyconsumption2012:1.35TWh

18 April 2018 Budget planning

A cost of ~6 BCHF and power ~200 MW are “reasonable” values

Focus TDR work on modules, RF and CE for costs; for power RF and magnets

Above: EU Design Study for X-Band FELs

2018-2020: http://compact-light.web.cern.ch

Beyond being a collaboration for CLIC, many

groups have their own X-band facilities and

components (see overview on the left)

In the CLIC preparation phase:

Take advantage of the widespread use of electron linacs, and rapidly increasing use

of X-band increase collaboration

An e-beam facility at CERN

ILC prep. phase project:

CERN coordination of European effort

R&D contracts

MoU annexes or similar (with MS and NMS collaborators)

Techn.Transfer agreements, EU projects.

Preparation Phase 2019-22: Organization and resources

A European ILC project in the preparation phase 2019-22: • Resources needed estimated to ~25 MCHF/year (material) and 60 FTE/year (personnel),

ramping up from 2019 • Move towards more engineering personnel • The organisational model above is used for existing studies at CERN, e.g. CLIC/HE-LHC/FCC

Choices and common activities

18 April 2018 Budget planning 9

CLIC prep.phase / year

• 21 MCHF (w/collaboration)

• 130 FTE (w/collaboration)

ILC prep.phase /year

• 25 MCHF (Euro-collaboration)

• 60 FTE (Euro-collaboration)

3.5 GeV machine

• 6.5 MCHF (CERN)

• 55 FTE (w/collaboration)

For the time being• Look at common areas in all scenarios – consider key topics or facilities 2019-2023

• Cover all existing existing agreements with (INFN, UK, etc) that go into 2020, it also covers CompactLight obligations, ARIES transnational access, LCC:

• By 2019-2020 we need to know where to go next to select between the circles on previous slide to for more solid and concrete planning

• No changes needed for 2018-19

• *in case of ILC ramp down after 2021 (move Xbox facilities partly outside) – other ILC activ. will come in
