The workshop focused on the application of ANAs to particle physics keeping
in mind the ultimate goal of a collider at the energy frontier (10\,TeV,
e$^+$/e$^-$, e$^-$/e$^-$, or $\gamma\gamma$). The development of ANAs is
conducted at universities and national laboratories worldwide. The community is
thematically broad and diverse, in particular since lasers suitable for ANA
research (multi-hundred-terawatt peak power, a few tens of femtosecond-long
pulses) and acceleration of electrons to hundreds of mega electron volts to
multi giga electron volts became commercially available. The community spans
several continents (Europe, America, Asia), including more than 62 laboratories
in more than 20 countries. It is among the missions of the ICFA-ANA panel to
feature the amazing progress made with ANAs, to provide international
coordination and to foster international collaborations towards a future HEP
collider. The scope of this edition of the workshop was to discuss the recent
progress and necessary steps towards realizing a linear collider for particle
physics based on novel-accelerator technologies (laser or beam driven in plasma
or structures). Updates on the relevant aspects of the European Strategy for
Particle Physics (ESPP) Roadmap Process as well as of the P5 (in the US) were
presented, and ample time was dedicated to discussions. The major outcome of
the workshop is the decision for ALEGRO to coordinate efforts in Europe, in the
US, and in Asia towards a pre-CDR for an ANA-based, 10\,TeV CM collider. This
goal of this coordination is to lead to a funding proposal to be submitted to
both EU and EU/US funding agencies. This document presents a summary of the
workshop, as seen by the co-chairs, as well as short 'one-pagers' written by
the presenters at the workshop.
