Particle physics has since long been a very international endeavourInternational roadmaps (European, Japanese, but also US) identify similar goals
Increased collaboration and exchange between different world regions is mandatory for maximising the chances of realisation, supports secondment between Europe and Japan in the area of accelerator science and projects
E-JADE addresses need of exchange of ideas on R&D and implementation of future accelerators for particle physics
• Basic accelerator R&D• Prototyping• Implementation• Management
Technical WP 1-3.WP4 and WP5 are “conventional”: management, dissemination, training
Project ran 2015-2018, prepared Spring 2014 in discussions with CERN management
• Considering options for collaboration with Japan more broadly

LHC: analysis, upgrade, R&D
E-JADE – WP1LHC consolidation, upgrades and R&D for future hadron machines
Task 1.3: injectors
Task 1.2: HL-LHC
Key WP dominated by Japanese secondments to CERNMain focus on Japanese contributions to the LHC programmeand the LHC machine upgrade This project also covered large upgrades of the LHC injectors Some initial secondments also for FCC-hh
Task 1.1: LHC operation/analysis

SuperKEKB
E-JADE – WP2Nanometre scale beam handling at the ATF-2
WP related to European participation in projects in Japan• ATF2: study facility at KEK relevant for future
Linear electron-positron colliders (being in Japan or at CERN)
• SuperKEKb: small high intensity electron-positron ring at KEK for flavour physics, but also very relevant future large rings as FCC-ee being considered at CERN
Our most successful WP, scheme well adapted
to such projects - also many students involved
ATF2: nanometre beams

Effective secondments to Japan in this WP but slower than expected ILC approval process in Japan. A fifth task called “Detector-related R&D and physics studies for the ILC” was implemented in Summer 2016 as an outcome of the midterm review in Santander. Several new institutes joined EJADE related to this extension.
Tasks 3.1 and 3.4 LC R&D and documentation
E-JADE – WP3Linear Collider targeted R&D
Task 3.2 MDI
Task 3.3 SRF
For CERN-KEK:X-band, CE, Cryogenics, tuners and couplers, beam-dump

KEK-DG Yamauchi set up a WG to develop a KEK-ILC action plan in May, 2015.
The KEK-ILC Action Plan was released in January 2016. It contains technical preparation
tasks and a human resource development plan for the pre-preparation phase (current
efforts) and the main-preparation phase (after “green sign” from MEXT). It focuses mainly
on a development plan for KEK.
“After having established a discussion group with DOE, discussions with Europe are
likely to become the next important topic for MEXT.”
Letter to CERN in 2016 concerning European planning.
On the European side it was suggested to use the EJADE H2020 MC project to prepare
the answer – the effort was started October 2016
The European ILC preparation plan was produced in 2018, presented to CERN Council
twice:
For EJADE institutes:
• CERN: S.Stapnes, CEA: O.Napoli, DESY: N.Walker/H.Weise/B.List, CNRS: P.Bambade/A.Jeremi, UK: P.Burrows, CSIC and CNRS: A.Faus-Golfe
• EJADE WP3 and centrally: T.Schoerner-Sadenius, M. Stanitzki
• TDR: B.Foster
This document formed the basis for the ESPP input document for ILC
concerning a potential European participation

1. Recovery from fire is underway, now in final cleaning stage.
2. Nextef-A is being reborn next spring as S-band high gradient test stand.
3. Nextef-B will recover X-band high power in summer next year using single
klystron.
4. We restart single-cell SW cavity tests.
5. We will try to find resource to recover Nextef peak RF power for CLIC by adding
another klystron.
6. Then we can restart high gradient test of CLIC prototype based on a new-design
QUAD with enough RF power.

Summary
E-JADE worked best (for Europe) to support activities at KEK (main example ATF2
and ILC preps), and for young researchers
Japanese researchers already extensively travel (including many longer stays) to
Europe (CERN)
Co-funding of Japanese secondees would make such programmes stronger
E-JADE useful for ILC organization in Europe
Secondments:
• Around 230 person-months of secondments from Europe - ~4k€/month, a similar
amount from Japan to Europe (these mostly for LHC and HL-LHC, with no EU support)
• Around 18% from CERN, mostly for WP1, 2 and 3 (HL, ATF/SuperKEKb, CLIC/ILC)
• WP2 (55%) and WP3 (30%) the largest by far in the project
Natural to consider such programmes if ILC moves into pre-lab state
CERN-KEK offices: KEK office at CERN very active, CERN office at KEK in ”wait and
see” state, consider in 2020 what to do longer term
X-band studies at KEK have been crucial, we hope the facility can continue to
operate after recovery – also important for Japanese industry involvement in
technology and Asian partners

WP 4: Management & Dissemination
• Tasks
• 4.1 Scientific and Financial Management (CERN & KEK): The management of the programme involves the organisation of programme events, managing the secondments of researchers and the financial planning, execution and reporting to the EU.
• 4.2 CERN & KEK Offices (CERN & KEK): Permanent offices at CERN and KEK will be set up, which will support the researchers during the duration of their secondment.
• 4.3 Communication (CERN & KEK): The Communication of E-JADE achievements experiences and results within the E-JADE programme will ensure most efficient sharing of knowledge and expertise of the seconded researchers. Annual meetings of all E-JADE participants will be organized as well as topical workshops as described in B4.3.1
• 4.4 Dissemination (CERN & KEK): A program for dissemination of information from E-JADE will be setup. This involves setting up public web pages and social media accounts as well as providing information for media and general public. The publication of results in scientific journal articles and participation in international conferences will also be monitored
1820 November 2019
WP 5: Training and Knowledge Transfer
• Tasks• 5.1 - Training: All beneficiaries and partners will provide an extensive,
relevant and high-quality schedule of training courses, individual coaching sessions and research experience periods to the researchers to be exchanged. These efforts will be directed towards the exchange of knowledge and expertise available at project partners, for the benefit of visiting and resident researchers. A detailed description can be found under section 4.3.1.
• 5.2 - Evaluation: In order to achieve the objective of increasing skills, knowledge and experience of the staff exchanged, the knowledge transfer schedule must be fully implemented (see Task 5.1). In parallel, as also described in WP 4, the consortium will develop and approve at the kick-off meeting an evaluation framework that will monitor the implementation of the knowledge transfer, and evaluate with individual participants to what extent the efforts conducted have been successful, meeting the individual and overall goals, and where/when any adjustments or improvements are necessary.
