This page contains information of a general nature on the "Faraday Cage" shield around the MDT chamber electronics. Please see the CDD at CERN for links to specific chamber design drawings.
Shielding effectiveness measurements have been performed on the MTD faraday cage. Measurements were made using a spectrum analyzer and various antenna configurations to quantify (in dB) the shielding effectiveness of faraday cage components. The measurements indicate the importance of adequate sealing of the faraday bottom plate to the MDT end plug surfaces.
