SHIM 2015 Swift Heavy Ions in Matter

For decades we have been involved in the selective excitation of the heavy atomic ions from Ar to U in the x-ray energy domain making use of a thin single crystal. The swift ions accelerated to ~70 % of the speed of light using the heavy ion synchrotron facility are guided in the silicon single crystal, and excited by a temporally oscillating strong Coulomb field arising from the periodical...

Precise data on electronic stopping powers for heavy ions are of high interest in various fields of research. Since more than one decade a new technique, which uses a combination of time-of-flight and energy detectors to collect continuous dE/dx data over a wide range of energies in a single measurement [1], has been successfully applied in different experiments. However, for high ion masses...

Active and passive optical waveguides are fundamental elements in modern telecommunications systems. A great number of optical crystals and glasses were identified and are used as good optoelectronic materials. However, fabrication of waveguides in some of those materials remains still a challenging task due to their susceptibility to mechanical or chemical damages during processing....

We are running a High Resolution Scanning Electron Microscope in the beam line of the UNILAC ion accelerator at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany, which has recently been extended also with an EDX-system and two micro-manipulators. This instrument allows us to in-situ investigate the structural and compositional development of individual objects and...
