Anomalous behaviour of laser-cooled fast ion beams
We have observed a sudden disappearance of intrabeam scattering in a laser-cooled stored Be beam at the Heidelberg Test Storage Ring. The transition takes place at about 10 ions corresponding to a mean ion distance of '50μm. The disappearance of IBS is accompanied by a decrease of the longitudinal temperature by more than two orders of magnitude. At the same time, the transverse width of the io...
متن کاملMeasurement of Time Dilation by Laser Spectroscopy on Fast Stored Lithium Ions
In this work frequency measurements on fast lithium ions as a test of time dilation are presented. The measurements are carried out at the Max Planck Institute for Nuclear Physics in Heidelberg using the storage ring TSR. The transition frequency of a two-level system in the lithium ion is measured using a Doppler-free fluorescence saturation spectroscopy. The spectroscopy is realized by two co...
متن کاملIntense Electron and Ion Beams
Material characteristics versus the number of electrons in the valence atom shell not used in the previously published papers are presented here. The electric field interaction with the collective electrons and the ion skeletons of the electrode material result in the initiation of the plasma formation (ecton) on the surface of one of the electrodes and the breakdown of the interelectrode gap. ...

متن کاملRadioactive Ion Beams for Astrophysics
The chemical element evolution of galaxies depends on nuclear processes that occur in various types of stellar environments throughout their lifecycle. These processes divide into two generic classes: processes that evolve over millions or billions of years involving reactions between stable nuclei, and processes that evolve explosively within seconds involving reactions between very unstable, ...
