Description

Particle accelerators underpin discovery across HEP, BES, NP, ARDAP, and beyond. Their future hinges on reliably delivering beams with higher intensity, higher phase-space density, and exceptional stability. Meeting these goals requires coordinated progress in source/injector physics, collective-effect mitigation, advanced diagnostics, and predictive control.

This workshop will explore the grand challenges outlined in the 2022 General Accelerator R&D Program’s Accelerator and Beam Physics Roadmap. How do we increase beam intensities for high charge injectors employing top-up or swap out injection techniques? Can we generate and accelerate ultra-low emittance beams to increase phase-space density orders of magnitude for light-source and other applications? And how will new diagnostic and controls tools be developed, validated, and integrated into routine operations to reach these goals?

As an outcome of this workshop, we will produce a white paper that defines the needs of injectors for future colliders and high‑brightness light‑source programs, sets quantitative performance targets, and outlines an experimental path forward, including required test-facilities and paths for AI/ML‑enabled diagnostics and controls.

To help focus the workshop discussions and to enable contributions from colleagues who may not be able to attend, we invite submissions of up to one page in length. More details may be found here.
