It has lead to important insight into the conditions of technical operation of naked Ge detectors in liquid nitrogen. The relatively large background from 222Ra diffusion is a problem unsolved up to now. The main problem realized, is, however, the increase of leakage current after long running of the detectors, caused by increasing surface impurity of the crystals. This led to serious restrictions of the high voltages applicable and finally to destruction of the detectors. The information GENIUS-TF delivered after almost three years of operation on the possibility of long-term operation of such experiments, may cast some doubts on the possibility of such experiments on larger scale in general. </font></a><br /> </b></td> </tr> </table> </center> <br> <h3><em> For more information, please look into articles: </em></h3> <!--<img src="redball.gif"> --> <hr> <h3> <!--<font color="#008000">--> I.V.
