Description
REGISTRATIONS ARE CLOSED
 
The ALEGRO (Advanced LinEar collider study GROup) Workshop gathers the advanced and novel accelerator community, and reflects the global ambition towards ultra-high energy colliders driven by wakefield acceleration technology, while also seeking engagement from HEP Theorists and Experimentalists. 
 

The 2026 edition will be held in person in Italy at the INFN-LNF - Via Enrico Fermi 60 - Frascati (Rome) from the 3rd to the 5th of March 2026. 

 
The workshop will concentrate on recent progress and next steps towards a self-consistent design of a linear collider based on novel-accelerator technologies, and on the physics cases for electron-positron, electron-electron and gamma-gamma colliders at the TeV frontier. Other applications of Advanced and Novel Accelerators to particle and high-energy physics will also be discussed.
There will be a session dedicated to the European Strategy for Particle Physics (ESPP) Update 2026.

 


Participants in the Workshop are invited to register via web using the online registration form (an INFN indico account is required, for those who have INFN AAI credentials, please use AAI log in). 

A registration fee (all included), as contribution to the Workshop organisation, includes lunches, coffee breaks, a welcome cocktail, a social dinner + bus to/from the restaurant and meeting materials.

Early Registration Fee of 350,00 Euros: 1 September 2025 - 31 December 2025 (payment must be completed within December 31)

Late Registration Fee of 400,00 Euros: 1 January 2026 - 15 February 2026

Those who need to apply for a VISA to enter Italy are kindly requested to ask the Workshop Secretariat for a formal invitation letter by e-mail.

CANCELLATION AND REFUNDS
All refund requests must be in writing by email to the Workshop Organisers as soon as possible.
Registration fee less 50,00 € as administrative fee, will be refunded if a request is made in writing to the ALEGRO2026 Secretariat (alegro2026@lists.lnf.infn.it) and received prior 31 January 2026. 
For "STORNI INFN" the deadline is January 15th.

Cancellations after this date will be non-refundable.
 

Registrations may be transferred to substitute delegates without incurring a fine.
