The GENIUS Project - Background and technical studies
  The potential of GENIUS as a dark matter detector is discussed. A study was performed to demonstrate the good behaviour of the proposed detector design of naked HPGe-crystals in liquid nitrogen. The expected background components were simulated and are discussed in some detail.With the obtained background GENIUS could cover a large part of the favoured MSSM parameter-space.
