摘要：A direct WIMP (Weakly Interacting Massive Particle) detector with a
neutron veto system is designed to better reject neutrons. An
experimental configuration is studied in the present paper: 984 Ge
modules are placed inside a reactor neutrino detector. The neutrino
detector is used as a neutron veto device. The neutron background
for the experimental design has been estimated using the Geant4
simulation. The results show that the neutron background can
decrease to O(0.01) events per year per tonne of high purity
Germanium and it can be ignored in comparison with electron recoils.
