Observation of a VHE Cosmic-Ray Flare-Signal with the L3+C Muon Spectrometer / L3+C Collaboration
The data collected by the L3+C muon spectrometer at the CERN Large Electron-Positron collider, LEP, have been used to search for short duration signals emitted by cosmic point sources. A sky survey performed from July to November 1999 and from April to November 2000 has revealed one single flux enhancement (chance probability = 2.6X10^{-3}) between the 17th and 20th of August 2000 from a direction with a galactic longitude of (265.02+-0.42)^° and latitude of (55.58+-0.24)^°. [...]

Study of the Solar Anisotropy for Cosmic Ray Primaries of about 200 GeV Energy with the L3+C Muon Detector / L3 Collaboration
Primary cosmic rays experience multiple deflections in the nonuniform galactic and heliospheric magnetic fields which may generate anisotropies. A study of anisotropies in the energy range between 100 and 500 GeV is performed. [...]

The Solar Flare of the 14th of July 2000 (L3+C detector results) / L3 Collaboration
Several experiments have reported observations on possible correlations between the flux of high energy muons and intense solar flares. If confirmed, these observations would have significant implications for acceleration processes in the heliosphere able to accelerate protons and other ions to energies of at least tens of GeV. [...]

A search for flaring Very-High-Energy cosmic-ray sources with the L3+C muon spectrometer / L3 Collaboration
The L3+C muon detector at the Cern electron-position collider, LEP, is used for the detection of very-high-energy cosmic \gamma-ray sources through the observation of muons of energies above 20, 30, 50 and 100 GeV. Daily or monthly excesses in the rate of single-muon events pointing to some particular direction in the sky are searched for. [...]

Recent Results and Perspectives of the Low Emittance Photo Injector at PITZ / Stephan, Frank ; Bähr, Jürgen ; Gensch, Ulrich ; Grabosch, Hans Jürgen ; HuiHan, Jang ; Krasilnikov, Mikhail ; Lipka, Dirk ; Miltchev, Velizar ; Oppelt, Anne ; Petrosyan, Bagrat et al.
The Photo Injector Test Facility at DESY Zeuthen (PITZ) was built to study the production of minimum transverse emittance electron beams for Free Electron Lasers. In November 2003 the electron beam from the RF gun was fully characterized at PITZ. [...]

The ability to produce high brightness electron beams as required for modern Free Electron Lasers (FELs) has been demonstrated during the first stage of the Photo Injector Test Facility at DESY Zeuthen (PITZ1). The electron source optimization at PITZ1 was successfully completed, resulting in the installation of the PITZ rf gun at the VUV-FEL (DESY, Hamburg). [...]

Beam-Based Procedures for RF Guns / Krasilnikov, Mikhail ; Bähr, J W ; Grabosch, H J ; Hartrott, Michael ; Hui Han, Jang ; Miltchev, Velizar ; Oppelt, Anne ; Petrosyan, Bagrat ; Staykov, Lazar ; Stephan, Frank
A wide range of rf photo injector parameters has to be optimized in order to achieve an electron source performance as required for linac based high gain FELs. Some of the machine parameters can not be precisely controlled by direct measurements, whereas the tolerance on them is extremely tight. [...]
