- Title
New Neutron Shielding in the Edelweiss-III Experiment.

- Abstract
In dark matter WIMP searches the fundamental background is due to neutron flux. Thus shielding plays a crucial role in attenuating this flux and consequently in suppressing nuclear recoil background events. The transition from EDELWEISS-II to EDELWEISS-III with a total fiducial mass of 24 kg and improved background rejection has required the modification of the neutron shielding. In this paper we describe the design of this new neutron shielding and give an estimate of the expected neutron rate in comparison with the EDELWEISS-II experiment.
