摘要：

The superconducting electron accelerator ELBE (Electron Linac with:high Brilliance and low Emittance) at the Research Centre Dresden-Rossendorf (Germany) serves. as a. high- intensity bremsstrahlung photon-source delivering a pulsed beam (26 MHz) with very short bunches (< 5 ps). The photons are being converted into positrons by means of pair production inside the target material thus forming an intense positroii source. The accelerator machine pulse is used as time reference allowing positron lifetime spectroscopy. We performed positron annihilation spectroscopy by pair production in different sample materials and used coincidence techniques to reduce the background due to scattered photons significantly in order resulting in spectra of extraordinary high quality.
