Abstract
Longitudinal Schottky signals from
a laser-cooled, spatially dense, ion
beam have been studied in
the ASTRID storage ring. The
fluctuation signals are distorted
by the effects of space charge, as
is observed in electron cooling experiments.However,the spectra also exhibit previously unobserved
coherent components. The ions' velocity distribution, measured by a
laser fluorescence technique, suggests that the coherence is
due to suppression of Landau damping. The observed behavior has
important implications for the attainment of a crystalline ion beam
in a storage ring.
