Cosmogenic activation of Germanium and its reduction for low background experiments
Production of Co and Ge from stable isotopes of Germanium by nuclear active component of cosmic rays is a principal background source for a new generation of Ge double beta decay experiments like GERDA and Majorana. The biggest amount of cosmogenic activity is expected to be produced during transportation of either enriched material or already grown crystal. In this letter properties and feasib...
متن کاملBackground reduction and sensitivity for germanium double beta decay experiments
Germanium detectors have very good capabilities for the investigation of rare phenomena like the neutrinoless double beta decay. Rejection of the background entangling the expected signal is one primary goal in this kind of experiments. Here, the attainable background reduction in the energy region where the neutrinoless double beta decay signal of Ge is expected to appear has been evaluated fo...
متن کاملRadiation shielding for underground low - background experiments
The design task of creating an efficient radiation shield for the new COBRA double-beta decay experiment led to a comprehensive study of commercially available shielding materials. The aim was to find the most efficient combination of materials under the constraints of an extreme low-background experiment operating in a typical underground laboratory. All existing shield configurations for this...
متن کاملPurification of cerium, neodymium and gadolinium for low background experiments
Cerium, neodymium and gadolinium contain double beta active isotopes. The most interesting are Nd and Gd (promising for 02 search), Ce (2 candidate with one of the highest Q2). The main problem of compounds containing lanthanide elements is their high radioactive contamination by uranium, radium, actinium and thorium. The new generation 2 experiments require development of methods for a de...
