5th European Advanced Accelerator Concepts Workshop

REGISTRATION IS CLOSED

The workshop will take place at LNF-INFN from the 20th to the 22nd of September 2021 in a hybrid format, followed by a EuroNNAC meeting on the 23rd of September.

Under present rules most of the workshop will take place in a virtual and reduced format, allowing an expectation of maximum of 40 people to attend in-person at the LNF-INFN, in Frascati (Rome, Italy).

For those participants who will be notified as "in presence", it will be requested to show EU covid-19 green pass or covid-19 certificate at the entrance of the LNF area and/or Bruno Touschek Auditorium due to the new Italian law issued on July 22, 2021. Here some useful information about travelling to Italy: link.

LNF-INFN decline all responsibility for any quarantines/isolations that may occur in the event of a positive COVID-19 case during the meeting.

The focus this year will be on 18 plenary talks and a one day event on the accelerator R&D roadmap discussions ongoing in Europe and the US.

The poster session and the usual parallel sessions of working groups cannot take place.

The European Advanced Accelerator Concepts Workshop (EAAC2021) has the mission to discuss and foster methods of beam acceleration with gradients beyond state of the art in operational facilities. The most cost effective and compact methods for generating high energy particle beams shall be reviewed and assessed. This includes diagnostics methods, timing technology, special needs for injectors, beam matching, beam dynamics with advanced accelerators and development of adequate simulations.

This workshop is organized in the context and with sponsoring of the EU/I-FAST funded European Network for Novel Accelerators (EuroNNAc4), a network of more than 60 institutes and universities. Additional sponsors for EAAC2021 include at the moment CERN, DESY and INFN. Given the impact of the Corona pandemic, NO program of student sponsoring will be offered in 2021.

The 5th EAAC will be followed by a half day EuroNNAc4 network meeting by invitation only (23th of September, 2021).

EAAC2021 scope:

• High gradient and multibunch acceleration in metallic structures (C-X-band and beyond) with innovative power generation schemes
• Plasma accelerators driven by modern lasers
• Plasma accelerators driven by electron beams
• Plasma accelerators driven by proton beams
• Dielectric structures and other novel technologies
• Novel schemes using advanced technologies (table-top FEL, plasma linear collider, medical imaging ...)
• Computations for Accelerator Physics Advanced beam diagnostics for beams and plasma
• Laser technology for advanced accelerators
