Abstract
The CELSIUS accelerator ring is equipped with a magnesium jet profile monitor which has been used to study transverse electron cooling of io n beams. Cooling times were measured by using a theory which takes int rabeam scattering into account. The results agreed with the cooling ti mes derived from the binary model. Mis-alignment between the electron and the ion beams was found to make a hole in the transverse beam emit tance which could be observed as a double peak on the beam profile mon itor. It was explained by negative cooling times for ions with small e mittances.
