1 st Townhall Meeting High Gradient Acceleration PlasmaLaser

1 st Townhall Meeting “High Gradient Acceleration (Plasma/Laser)” R. Assmann (DESY/INFN) & E. Gschwendtner (CERN) for the Expert Panel on “High Gradient Acceleration (Plasma/Laser)” Remote Meeting via Zoom 30 March 2021 R. Assmann, E. Gschwendtner 1

European Strategy for Particle Physics • The European Strategy for Particle Physics is updated every 5 years in a procedure based on wide community input. • Many of us provided input to this process: • Written statements from European Network for Novel Accelerators (Euro. NNAc), AWAKE, ALEGRO and Eu. PRAXIA. • Several talks at meetings. • Strategy defines future directions and priorities for particle physics in Europe and for CERN. Last update: 2020. • Outcome a great success for advanced accelerators: • Importance of accelerator R&D in general. • Explicit mentioning of plasma and laser high gradient acceleration. • Request for accelerator R&D roadmap, adequate resources, priorities, deliverables for next decade, synergy with other science fields, … R. Assmann, E. Gschwendtner 2

Panel mandate I Five tasks. Based on European Strategy and discussions inside panel and with LDG 1) Develop long-term roadmap for the next 30 years towards a HEP collider, other HEP applications. Q: Where do you see HEP applications of advanced accelerators in 30 years? 2) Develop milestones for next 10 years taking into account the plans/needs in related scientific fields as well as the capabilities and interests of the stakeholders. Q: What are the important milestones for the next 10 years to get there from today? Q: What is the synergy with related fields? Q: What is the role of your work here? R. Assmann, E. Gschwendtner 6

Panel mandate II Five tasks. Based on European Strategy and discussions inside panel and with LDG 3) Establish key R&D needs 4) Give options and scenarios for matched to the existing and European activity level and planned R&D facilities. investment. Q: What key R&D needs can be achieved in existing R&D facilities? Q: What can be done with the existing and planned funding base? Q: What is the role of the already planned future facilities in Europe and world-wide? Q: In case additional support is needed for a milestone: What is required? Q: Is a completely new facility needed? R. Assmann, E. Gschwendtner 7

Panel mandate III Five tasks. Based on European Strategy and discussions inside panel and with LDG 5) Define deliverables and required resources to be achieved until next European strategy process in 2026, in order to enable as best as possible critical decisions for R&D lines for HEP. Q: What should be propose as deliverables until 2026? Please list in order of priority. Q: Is the R&D work for each of those deliverables already funded and, if not, what additional resources / support would be needed? Q: Are additional structures needed beyond existing networks and projects, e. g. a design study for a collider or an advanced accelerator stage? R. Assmann, E. Gschwendtner 8
