H. Danared, ELECTRON COOLING AT CRYRING WITH AN EXPANDED ELECTRON-BEAM, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 391(1), 1997, pp. 24-31
Studies of electron cooling with an adiabatically expanded electron be
am have been performed at CRYRING. Measurements of the longitudinal dr
ag force using three different methods are described and are compared
with measurements at other electron coolers. The processes that determ
ine the electron temperature, longitudinally and transversally, are re
viewed, and the effect of the beam expansion on these processes is dis
cussed. It is described how the electron temperature can influence the
outcome of recombination measurements, and how such measurements can
be used to determine the electron temperature. and an example of such
a measurement is given.
