2027 Perspectives and Priorities

• Marco Wischmeier (EUROfusion PMU)

Duration: 15'+10' Topics: Identification of budget requirements for 2027 and discussion on relative prioritization, including desired additional operational time of facilities, as input to the PB in March and to the GA in April (GA expecting a prioritized shortlist). Discussion on mid and long term EUROfusion scientific priorities for JT-60SA (discussion on update of present JT-60SA priorities) ITER MoU breakdown between WP and corresponding resources Discuss issue of materialization of joint phd or post-docs in the collaboration with ITER HoD will touch on the individual WP aspects in intro to provide own perspective Annual technical reporting length

2027 WPPWIE

• Sebastijan Brezinsek (FZJ)

Duration: 15'+10' Topics: For the next PB PWIE will request the conversion of 2 container for JET into resources for analysis and machine time post DT samples. I made the proposal last year, but it shall be proposed in Apri (after discussion with Marco last year) PWIE will request 2 additional packages to recover the loss of two main areas: tritium studies and dust studies.. discussions with WPDES about the "joint" activities and desire to join forces. Lack of resources in this area. PWIE will propose a further project dealing with MEMENTO/RE simulations. Try to recover the content of an EEG activity as the person left VR Request budget for PWIE specific experiments under WPTE. PWIE understand, that there is not enough budget in TE, but it is for the PWIE community essential to have a "REAL" benchmark experiment for W migration, influx and retention in ITER-like configuration. This is only RELEVANT for AUG and requires specific time to get enough fluence. This will feed directly into the prediction if ITER. Issues with ERG or EEG as the "selection team experts"/panel may not be aware of ITER priorities. Discuss desire of strategy for an additional finance scheme.

2027 WPTE

• Emmanuelle Tsitrone (CEA)
• Nicola Vianello (ENEA)

Duration: 15'+10' Topics: Discussion on mid and long term EUROfusion scientific priorities for JT-60SA (i.e. revise the MoU priorities): 1. Development and investigation of high performance scenarios compatible with future W-PFCs, 2. Avoidance and mitigation of disruptions and runaways, 3. Fast ion physics, 4. Development and validation of high-level real-time control strategies. Additional % of TE machine ops in 2027 ? Additional resources needed for Scientific Exploitation of TE devices in 2027 (→ mission budget, even more if more machine time granted)  Additional resources for JT-60SA 2027 Additional Resources and plan for interpretative and extrapolative modelling (+ connection with WTM)

2027 General Discussion

2027 Proposed Prioritization

Dinner

FP10 outline and activities in 26-27 towards the future

• Marco Wischmeier (EUROfusion PMU)

Duration: 20'+10' Topics: BEST - What are the views on the required level of engagement?  Strategy for international collaboration (EU-US/EU-KR/EU-China) (here might also be EU-CA and EU-India) Expected timeline of devices and information or /needs on the development of the smaller devices inside Europe (MAST-U, TCV, WEST, AUG, W7-X) Issue of collaborating with private companies How to keep competence and at the same time reinforce the operativity and the scientific output of the many subsystems in delivery to QST? The present status is that whatever subsystem has passed the acceptation phase (commissioning) is QST property and EU teams that developed it are treated as a normal user. How to develop the support/interaction with DTT? Required development of human resources and their profile. Is there a need for a central physics unit at PMU to accelerate activities that are to be defined high priority and for which a higher funding rate would be required similar to DCT/WPDES as otherwise certain physics projects risk not to be completed in time ? How do we want to join ITER experiments? Desire for discussion by PLs on: “ITER needs to be a success and the commission will see this. Our strategy?”

WPTE: FP10 and activities in 26-27 towards the future

• Emmanuelle Tsitrone (CEA)
• Nicola Vianello (ENEA)

Duration: 20'+10' Topics: Analysis of the BEST research plan by the PLs/TFLs and recommendation of items that WP/TFLs consider essential and/or beneficial to the long term scientific programme, beyond FP9, in view of the available time lines for JT-60SA, DTT and ITER. What can we gain in BEST for the benefit of the EU programme and importantly the EU preparation for ITER exploitation? Long-term exploitation of JET data and participation of non EU/private partners: i.e. JET (D-T) data analysis strategy to be proposed and for discussion; Long term strategy on documentation/reproducibility and Data Management Plan interaction (for JET and other TE devices) Strategy for international collaboration (EU-US/EU-KR/EU-China) (here might also be EU-CA and EU-India) ; e.g. role of SPARC for progress in SSRLs  (even independently of any possibility for EUROfusion itself to collaborate with SPARC) ? JT-60SA - issues to reach a W-compatible divertor plasma solution

WPSTEL: FP10 and activities in 26-27 towards the future

Duration: 15'+10'

WPSA: FP10 and activities in 26-27 towards the future

• Carlo Sozzi (ENEA ISTP-CNR Milano)

Duration: 10'+5' Topics: Lessons learnt from JT-60SA enhancements to be applied to other future devices Should there be an Enhancements WP? Scheme of EU participation to JT-60SA; Science, Operations, Enhancements. Should/Will this go under EuF, or F4E, or hybrid? How to keep competence and at the same time reinforce the operativity and the scientific output of the many subsystems in delivery to QST. The present status is that whatever subsystem has passed the acceptation phase (commissioning) is QST property and EU teams that developed it are treated as a normal user.
