Ultra-low Emittance Bunches from Laser Cooled Ion Traps for Intense Focal Points

Laser-cooled ion traps are used to prepare groups of ions in very low temperature states, exhibiting such phenomena as Coulomb crystallization.  This corresponds to very small normalized RMS emittances of 10^-13–-10^-12 m, compared to typical accelerator ion sources in the 10^-7–-10^-6 m range.  Such bunches could potentially be focused a million times smaller at a given energy and increase the specific luminosity and energy efficiency of colliders.  Novel high density focal points also appear possible, with bunches compressed smaller than an atom and particles colliding within a single bunch.  At ~TeV energies, these approach the nuclear density and offer a way of producing neutron star matter (neutronium) on the scale of tens of thousands of nucleons, as well as other custom nuclear matter in the lab.

Dear Scott, 

Thank you for the invitation, I gladly accept to give a talk at this workshop.

It will probably involve how using ultra-low emittance sources (crystalline beams) can get either better luminosity from a given number of particles, or produce high density foci at higher energies.

Hi Stephen,

 

We’d like you to come to speak at the conference "Physics At The Highest Energies With Colliders," which is part of the workshop “Exploring the Energy Frontier with Muon Beams” workshop (https://www.ggi.infn.it/showevent.pl?id=507
Event at Galileo Galilei Institute - Istituto Nazionale di Fisica Nucleare
Exploring the energy frontier with muon beams Jun 30, 2025 - Aug 01, 2025

) at the Galileo Galilei Institute in Florence. The conference will be the week of July 28th. The idea of the conference is to explore what would come after the 10 TeV pCoM machines that were discussed in the P5 report: how could accelerators reach those even higher energies, what would be the physics interest at those energies, and what detector technologies would be required. The organizers were very interested in your explorations of fundamental accelerator limitations that you talked about in your IPAC 2018 paper, whether you have thought more about those ideas, and what it might mean for an accelerator that might follow a FCChh or 10 TeV muon collider.

 

Do you think you would be interested in and able to present at the conference?

 

Thanks,

 

-Scott
