EMC: A mapping for the CMS experiment

The Compact Muon Solenoid (CMS) is one of the four high-energy physics experiments for the LHC. Describing the electromagnetic (EM) environment of CMS is of major importance for determining and solving problems related to electromagnetic interference, grounding and shielding. This thesis addresses the EMC studies conducted for the CMS experiment to define the baseline of the future CMS EMC policy. The EMC study has been focused on the power supply distribution system. For that purpose, a simplified scheme of the power supply system has been used in this research work to address EMC studies. These studies are mainly focused on the quantification of the FEE sensitivity to conductive noise coupled through the input/output cables, the noise generated by power supplies and the noise propagation effects present in the detector. Also, the magnitude and effects of transient signals disturbing the power supply system are introduced.
