Foto dell'apparato Nemesis nel laboratorio DAMA a Roma Tor Vergata - FASE I

During installation

NEMESIS is made of 8 double modules. In each half-module a ZnS(Ag) detector is view by a PMT and is optically decoupled by the one in the other half-module; the two detectors in the same module work in delayed coincidence. Here some phases of the assembling of a module are shown.



Again during installation of the 8 double modules (the 4 on the front are mainly viewed). The half-modules and the whole set-up are maintained in evaporating Nitrogen atmosphere. NEMESIS - Phase I completed (Thesis by G. Russo).

NEMESIS - Phase II

second generation set-up with larger effective solid angle; final results published.
