  1. Cu of Norddeutsche Affinerie (Hamburg, Germany) melting casting cathodes anodes NOSV quality 99.9975% (1-4 ppm O2) 97-99 % + 2000 ppm O2 +... Ni: % IN ORE < !-2 ppm Co: about 5 ppm < 1 ppm 40K: 7.5  1.0 mBq/kg < 0.088 mBq/kg 226Ra: 1.8  0.4 mBq/kg < 0.020 mBq/kg 228Th: < 0.44 mBq/kg < 0.023 mBq/kg under investigation E.Pernicka

  2. Norddeutsche Affinerie is very open to our needs take special care in the cathode production and provide the cast material a few days after the removal from the electrolyses for further processing without forming  = 8.7 g/cm3 after hot forming: 8.92 g/cm3 full of small porous mainly containing H2 Acid cleaning difficult (sticks in pores) electropolishing o.k. smoothes the surface possible electrodeposition or selfdepostion of 210Po is investigated by M. Wojcik

  3. + 270 d 125 kg NOSV Cu for LENS measured with GeMPI M. Laubenstein G. Heusser preliminary +
