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, compensating for the lower number of ions per bunch. Such an ultra-low emittance source could enable high-specific-luminosity colliders where reduced beam current and apertures are needed to produce a given luminosity. Further advances needed to enable such colliders include linear, helical or ring cooling channel designs for increased bunch number or current throughput. Novel high density focal points using only a single bunch also appear possible, where the high density particles collide with themselves. At collider energies ~100 GeV, these approach the nuclear density and offer a way of studying larger quantities of neutron star matter and other custom nuclear matter in the lab.
