AMOC2

The GiPS facility (Gamma-induced Positron Spectroscopy) has been set up for user operation at the Research Center Dres-den-Rossendorf, Germany, in 2009. A bunched electron beam from a superconducting linear accelerator (LINAC) in cw mode (bunch length <5 ps; repetition time 38 ns) gener­ates bremsstrahlung photons up to 20 MeV. The photon beam hits the sample and positrons are generated by pair production in the whole sample volume. All important posi­tron techniques are applied to study the real structure of bulky samples (coarse powder, samples for non-destructive testing, liquids, activated samples). Due to the unique time structure, positron lifetime and AMOC (Age-Momentum Correlation) measurements are possible. Coincidence Doppler Broadening Spectroscopy (CDBS) is also available. The spectra of all techniques were proven to exhibit extraordinary quality, as is reported by Reinhard Krause-Rehberg et al. on p. 2451 ff.

BACK COVER Positron annihilation, as a well-established experimental tool in the materials science community, provides unique informa­tion about the behavior of the material microstructure after radiation treatment. The experimental simulation of radiation damage by charged particle implantation is, as a first ap­proach, a very reasonable way to study radiation embrittle-ment. The article presented by Vladimir Krsjak etal. on p. 2339ff. discusses this timely topic on recent experiments on helium implanted Fe-Cr model alloys. Simultaneous re­sults from positron beam and conventional depth profiled positron lifetime techniques are demonstrated. In the cover picture, the intensity of the positron lifetime component /3

characterizes the presence of large open volume defects.
