Presentation Transcript
recent developments
Recent developments
  • two new Germanium detectors, similar to GeMPI detector (in fact they are called GeMPI-2 and GeMPI-3, GeMPI-2 still under test; GeMPI-3 arrived on October 25th, shielding still to be built)
  • new space available in hall A … but it is already almost filled up …

material screening old data expanded uncertainties and decision thresholds with k 2
Material screening (old data)(expanded uncertainties and decision thresholds with k=2)

forthcoming results and analyses
Forthcoming results and analyses
  • Lexan
  • electronic components (in measurement also for other experiments, but up to know nothing “clean”, O(hundreths of Bq/kg)
  • Kapton coax cable (only 30 g, now ca. 12 days)

GERDA Meeting @ Tübingen, TG 11

still the same question marks
Still the same question marks
  • Time schedule for measurements ?
  • List of materials to be measured ?
  • Required sensitivities ?
  • Intercomparison between radioactivity analysis laboratories ?
  • Intercomparison between screening techniques ?
