Abstract
Electron cooled bunched proton beams in the IUCF cooler are nearly com pletely space charge dominated longitudinally, meaning that the longit udinal charge density of the bunch is, to first order, determined by t he balance between the;internal force of the electrostatic repulsion b etween particles and the external force of the applied radio frequency focusing field. This leads to a number of phenomena, which have not b een observed before. In addition, the installation of a transverse bea m profile monitor in the IUCF cooler allowed us to investigate various proton beam properties, such as space-charge tune shift, correlation between transverse and longitudinal beam profiles and transverse cooli ng rates as a function of beam current and energy.
