86. Pioneering experiments in dark matter and neutrinos

Talk

We start with the early applications of Ge detectors for fundamental physics by the group of Ettore Fiorini’s search for double-beta decay of Ge-76. This was followed by the early work of the Battelle-Carolina Collaboration, IGEX, then MAJORANA. Werecognize parallel efforts by the Heidelberg group, andspecial background reduction by GERDA and LEGEND using their liquid Ar emersion technique....

59. The BOREXINO low-background techniques

Talk

The BOREXINO solar neutrino experiment was a pioneer in the suppression of radioactive background. The first real-time detection of sub-MeV solar neutrinos became possible only by a strict radiopurity control program.

That started with a smart detector design, in which the mass of the scintillator-containing vessel was ultimately minimized. It continued with the selection of radiopure...
