Abstract
A first temperature measurement of the expanded electron beam from a super- conducting magnet in the cooler of CRYRING is reported. It is based on dete ction of a dielectronic recombination resonance in C2+. For this measuremen t C3+ was stored in the ring at 3 MeV/amu energy. A fit to the resonance wi th free transverse and longitudinal temperatures gave 3.9 x 10(-3) eV and 4 .5 x 10(-5) eV,respectively. The result is also compatible with the values of 10(-3) eV for the transverse and 6.7 x 10(-5) eV for the longitudinal co mponent, in good agreement with expected values.
