Abstract
Longitudinal cooling forces have been measured for heavy ions from C6+ to U92+ at various energies from 50 to 360 MeV/u. Two experimental methods are described which offer the opportunity to measure the cooling force over the whole range of relative ion velocities from zero to 107 m/s. Measurements for various ion species are presented which show a pronounced deviation from the expected q2 scaling in the regime of low relative ion velocities. Further investigations concerning the influence of the magnetic field strength in the cooler revealed no significant influence.
