17. How the measurement is performed
The ratio of primary over secondary
signal depends on the kind of
particles producing excitation
and ionization
This discrimination method
rules out the backgroung
Induced by gammas and
electrons
Finally, the shielding from neutrons allows to discriminate
WIMP induced interactions 17
