Calibration of Radioactive Sourcesactive sources of a given radionuclide with known activity. It is the task of national metrology institutes (NMIs) and other calibration laboratories to provide corresponding activity standards which are required in nuclear medicine, environmental radioactivity, industry, and several other research

Gaseous Detectorsdrove the progress in experimental particle physics. A true innovation in detector concepts came in 1968, with the development of a fully parallel readout for a large array of sensing elements – the Multi-Wire Proportional Chamber (MWPC), which earned Georges Charpak a Nobel Prize in Physics in 1992

Tracking Detectors fields of nuclear physics, particle physics, and astro-particle physics. To understand and analyze the physics processes under study at these experiments, the reconstruction and precise determination of all particle flight paths of each event is important. From these tracks, parameters such as the
