November 2017 - The ECHo (Electron Capture in Holmium Experiment) team performs experiments at DREAMS.
Development of AMS at DREAMS for experimental determination of the ratio 163Ho/166mHo in ECHo samples. The long-lived 166mHo (t1/2=1200 a) is an unwanted by-product of the 163Ho (t1/2=4570 a) production, which is reduced to ultra-low levels (~10-9) after sophisticated mass separation. For a background-free measurement of the 163Ho spectrum in the ECHo metallic magnetic calorimeters the absence of 166mHo is critical.
June 2017 - DREAMS user Lisa Luna (U Potsam; now: NewClimate Institute for Climate Policy and Global Sustainability, Berlin) receives the graduation award (1.000 Euro) of the university of Potsdam 2017. She graduated in geosciences with her MSc work "A glacial chronology and cosmogenic nuclide cross calibration from the central southern Andean Plateau (Puna, 24°S)“. The university of Potsdam gives this yearly award to persons who show a high potential for scienctific work and further qualification. The work was performed under the supervision of Bodo Bookhagen, Institute of Earth and Environmental Science. Further information (in German only) can be found here: "Alumni des Monats 06/2017 - Lisa Luna ".
