Agenda and Plans
ALEGRO Workshop, SLAC
March 4-6, 2025
Welcome!
2
Thank you for joining us at SLAC. We are thrilled to have you here for the workshop.
This is a workshop, not a conference. You are here to propose new ideas, challenge the status quo, and engage with your fellow attendees.
You will hear a lot about the 10 TeV Wakefield Collider Design Study during this meeting. We are just starting the design study. All ideas are on the table!

Each Working Group Session has one or more responsible persons (RPs).
Responsibilities include:
Some Working Group Sessions have contributed talks.
In general, we encourage contributed talks but want to leave plenty of space for discussion.

Banque this evening at 6:30PM at Chef Chu’s in Los Altos.
Fun fact: Wicked director Jon Chu is the son of the owners.
It is a 20 minute drive from SLAC to Chef Chu’s. We will carpool!
If you have a car and take people from SLAC to Chef Chu’s, please sign up during the coffee break.
If you need a ride, there will also be a sign up form.
Red Team/Blue Team
17
We are planning a Red Team/Blue Team panel discussion for Thursday. The session is shifted to 9:30AM.
5-6 panelists on each team. Panelists have been contacted.
The Red Team and Blue Team will debate against and for the following propositions.
1. The Physics Case for a 10 TeV Wakefield Collider is compelling and competitive with other 10 TeV pCM concepts, regardless of collision type (e+e-, e-e-, gamma gamma).
2. Particle detectors can operate with the large beamstrahlung backgrounds that come from 10 TeV collisions.
3. Recent work by the HALHF collaboration indicates that major costs for plasma-based colliders come from “conventional” systems, such as the drive beam RF linac. Nevertheless, wakefield colliders will ultimately be cheaper than other 10 TeV pCM options.
4. Operations propositions:
- The 10 TeV collision energy can be held constant, even if a wakefield acceleration stage is “lost”. Brief deviations in energy are acceptable.
- 1 nanometer-wide beams can be brought into collision and remain aligned.
- Beam losses in the wakefield accelerator linac will be manageable and in-person maintenance can be performed.
5. Roadmap: A path to a 10 TeV Wakefield Collider exists, regardless of whether the 10 TeV machine is an upgrade of an existing Linear Collider or a green field project.
