The superconducting linear accelerator ELBE has a 200W at 1.8 K cryogenic plant. Two cold compressors are used for recompression of the Helium at the 4 K level and for stabilising the pressure in the accelerator cryostat. The talk will give an overview over the ELBE cryogenic system and will focus on the operation experience with the cold compressor system and the filling modes of the cryostat. Specific problems of the ELBE Helium plant concerning purity, maintenance and reliability will be discussed.
