Chemical Elements as Tracers of the Evolution of the Cosmos

LUNA Laboratory for Underground Nuclear Astrophysics (Assergi, Italy)

LUNA, the world's first underground accelerator. It is placed in the Gran Sasso underground laboratory.

Deep underground in the Gran Sasso, the cosmic-ray induced background is suppressed by six orders of magnitude. This enables highly sensitive measurements of nuclear reactions of astrophysical importance. There, INFN Italy operates the world's largest underground accelerator including the world's first underground ion accelerator.

The LUNA laboratory includes three ion accelerators:

  1. LUNA 50 kV accelerator, running from 1994-2001.
  2. LUNA 400 kV accelerator, running since 2001.
  3. LUNA-MV 3.5 MV accelerator, under construction and to start in 2019.

The data gained at LUNA are regularly summarised in review papers:
