This increase cannot be accommodated using current methods at the Compact Muon Solenoid (CMS) detector. Also, increased levels of ionizing radiation may interfere with muon endcap electronics. Unreliable performance of the L1 and endcap electronics can compromise physics studies. To determine if the upgraded electronics will function in the improved LHC environment, an irradiation study of the upgraded Muon Port Card (MPC) is performed. Additionally, Global Muon Trigger (GMT) muon isolation using the upgraded Muon Sorter (MS) is presented to reduce the L1 rate. It is determined that the upgraded MPC will operate properly, and that GMT muon isolation alone is not a viable method of rate reduction. Therefore, the MPC upgrade and GMT muon isolation will be implemented in the upgraded CMS detector.application/pdfengCopyright is held by the author, unless otherwise indicated.
