Description
The direct search for dark matter experiment, XENON100, using liquid
xenon has been in the process of taking data since January 2010 and will con-
tinue to do so for another year to reach a never yet achieved sensitivity on the
WIMP cross section and ultimately, maybe detect a WIMP.
In addition, the experiment is already being pushed towards its next phase,
XENON1T, which will be much larger with a fiducial volume of about 1 ton
of liquid xenon. Reducing the background, it would be a hundred times more
sensitive.
While the previous phases were located at the Laboratori Nazionali del Gran
Sasso (LNGS), in Italy, the location of XENON1T is still uncertain. One of the
considered option is to put it in the Laboratoire Souterrain de Modane (LSM),
in France.
The LSM site and its different level of gamma, neutron and muon background
with an emphasis on the muon induced neutrons coming from the environmental
rocks, have been investigated.
Considering the available space at LSM and the final background level nec-
essary for a dark matter search, an efficient and optimal shielding design has
been established.
All the results of these studies will be presented in this poster.
