The GiPS facility (Gamma-induced Positron Spectroscopy) has been set up for user operation at the Research Center Dresden-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 (© 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
