Abstract:

Germanium semiconductor detectors have become the “gold standard” for measuring the energies and intensities of gamma rays. With unsurpassed energy resolution and well-understood response, they have evolved from the early Ge(Li) detectors of a few cm3 (developed by George Ewan and others) to today’s hyper-pure Ge detectors with volumes up to 600 cm3. They have become the work-horse of radio-assay, beta decay, in-beam nuclear structure experiments, and even used for gamma-ray astronomy. In recent decades, new operating modes for Ge detectors have also enabled their use in the search for Dark Matter.

The development of Ge detectors, and of large arrays of such detectors for nuclear physics experiments, will be discussed, together with some of the principles behind their operation. I will then present some recent developments in novel systems, focusing in particular on applications for in-beam spectroscopy and searches for neutrinoless double beta decay and dark matter.

Free Admission. Refreshments will be provided.
