HALHF: a hybrid, asymmetric, linear Higgs factory using plasma- and RF-based acceleration. Backup Document Open
This document expands on the Comprehensive Summary submitted to the EPPSU 2026. It contains details on aspects of the HALHF project that could not be fitted into the Summary. Some sections contain work that is still preliminary and/or stat…

Proton-Driven Plasma Wakefield Acceleration for Future HEP Colliders Open
We discuss the main elements of a collider facility based on proton-driven plasma wakefield acceleration. We show that very competitive luminosities could be reached for high energy $e^+e^-$ colliders. A first set of parameters was develop…

HALHF: a hybrid, asymmetric, linear Higgs factory using plasma- and RF-based acceleration Open
HALHF is a hybrid linear collider that uses electron-driven plasma-wakefield acceleration to accelerate electrons to high energy while using radio-frequency cavity technology to accelerate positrons. The most cost-effective solution collid…

Latest updates and results from the Fluorescence detector Array of Single-pixel Telescopes (FAST) Open
The Fluorescence detector Array of Single-pixel Telescopes (FAST) is a next-generation cosmic ray experiment aiming to observe cosmic rays above 1019.5 eV with unprecedented statistics. To achieve this, FAST will utilise low-cost, easily d…

Reconstruction procedure of the Fluorescence detector Array of Single-pixel Telescopes Open
The Fluorescence detector Array of Single-pixel Telescopes (FAST) is one of several proposed designs for a next-generation cosmic-ray detector. Such detectors will require enormous collecting areas whilst also needing to remain cost-effici…

The AWAKE Run 2 programme and beyond Open
Plasma wakefield acceleration is a promising technology to reduce the size of particle accelerators. Use of high energy protons to drive wakefields in plasma has been demonstrated during Run 1 of the AWAKE programme at CERN. Protons of ene…

Design of the AWAKE Run 2c transfer lines using numerical optimizers Open
The Advanced Wakefield (AWAKE) Experiment is a proof-of-principle experiment demonstrating the acceleration of electron beams via proton-driven plasma wakefield acceleration. AWAKE Run 1 achieved acceleration of electron beams to 2 GeV and…
