Abstract: Sunset solar axions traversing the intense magnetic field of the CERN AxionSolar Telescope CAST experiment may be detected in a Time Projection ChamberTPC detector, as X-rays signals. These signals could be masked, however, bythe inhomogeneous background of materials in the experimental site. A detailedanalysis, based on the detector characteristics, the background radiation atthe CAST site, simulations and experimental results, has allowed us to design ashielding which reduces the background level by a factor of ~4 compared to thedetector without shielding, depending on its position, in the energy rangebetween 1 and 10 keV. Moreover, this shielding has improved the homogeneity ofbackground measured by the TPC.
