Primary physics goal is the search for axion like particles in a photon regeneration experiment. Central part of the experimental setup is a five Tesla strong superconducting HERA dipole magnet. During two operation periods in the years 2007 and 2008 we have collected first data and explored the sensitivity of the setup. A Fabry Perot laser cavity is being set up in order to increase the sensitivity by more than one order of magnitude.6 pages, 5 figures, contribution to 4th Patras Workshop on Axions, WIMPs and WISPs at DESY June 2008High Energy Physics - Experimenttext
