DAMA/LIBRA Experiment
(Large sodium Iodide
Bulk for RAre processes)
DAMA/LIBRA target-detector mass: ~250 kg highly radiopure NaI(Tl)
New NaI(Tl) detectors built after a 2nd generation R&D
(new materials selection, new dedicated protocol and physical/chemical
radio-purification of powders)
New electronics and DAQ
Improvements of the installation and of all the parts of the set-up
Works for the disinstallation of 100 kg NaI set-up, for installation
improvements and for the installation of DAMA/LIBRA started on July/August 2002.
In particular, all procedures involving
detectors, PMTs, etc. have been performed in
HP Nitrogen atmosphere
DAMA/LIBRA started preliminary measurements in March 2003
First data release in April 2008 (exposure of 0.53 ton x yr)
First upgarding in September 2008
