  abstract  = {The thesis deals with ions stored in an electrostatic ion beam trap. In the first part of the thesis the so-called self-synchronization effect is discussed. It is demonstrated that the time a bunch of injected ions is conserved by the self-synchronization effect depends on the number of injected ions. In the second part of the thesis the cooling of small anionic cobalt and copper clusters is addressed. Measurements on anionic copper clusters consisting of four to seven atoms are presented and the decay of hot clusters is observed in order to draw conclusions on the internal temperature and the cooling process itself. Afterwards measurements on Co4- are discussed and a measurement scheme based on laser induced delayed electron emission is presented enabling to monitor the internal energy distribution of the clusters over storage time in a temperature-controlled environment. The cooling of initially hot clusters as well as the heating of initially cold clusters were observed.},
