A compact high-current 50 kV ion accelerator facility including a wind
owless gas target system, a beam calorimeter, and detector telescopes
in close geometry has been built and tested. The data acquisition and
analysis involved a multiparameter system and a Monte Carlo program. T
he LUNA facility, presently installed at the Gran Sasso underground la
boratory, is a pilot project focused initially on cross section measur
ements of the He-3 (He-3, 2p)He-4 reaction within the thermal energy r
egion of the sun. To achieve this goal, the experimental sensitivity h
as been improved by more than four orders of magnitude over that of pr
evious work.
