  There are several background sources which may affect the analysis of data
and detector performans at the CLIC project. One of the important background
source is halo muons, which are generated along the beam delivery system (BDS),
for the detector performance. In order to reduce muon background, magnetized
muon sweepers have been used as a shielding material that is already described
in a previous study for CLIC [1]. The realistic muon sweeper has been designed
with OPERA. The design parameters of muon sweeper have also been used to
estimate muon background reduction with BDSIM Monte Carlo simulation code [2,
3].
