Description
A sudden reduction of momentum spread, and under certain conditions also of
Schottky-noise power, has been observed with electron-cooled beams at a few
ion storage rings. This has been interpreted as an effect of one-dimensional
ordering of the beams, such that the ions line up after one another in the
ring. A brief overview of subject of beam crystallization or beam ordering
is given, and results from observations and measurements of beam ordering at
CRYRING in Stockholm are given together with a model of the ordered beam.
