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