Optimization Of Cms Endcap Muon Electronics For Major Physics Goals At Lhc

A Large Hadron Collider (LHC) is expected to discover the Higgs particle(s) and will search for new physics beyond Standard Model (SM). However, the LHC environment is the most challenging one in High Energy Physics (HEP) with respect to the range of physics events and their expected rates. An optimized per major LHC physics goals approach to Compact Muon Solenoid (CMS) endcap front-end and readout electronics is investigated. This electronics is based on a low-noise Logarithmic Charge-to-Time and Time- to-Digital Converters that have very low readout latency. Extensive measurements and simulations were conducted not only to prove fulfillment of the design objectives but also to justify a radical change from the baseline approach. Far more superior performance of these circuits allows for digital readout architecture that will solve readout of Cathode Strip Chambers (CSC) problems such as event rate capability, resolution, integration density, radiation hardness and can potentially greatly simplify search for different physics events in a digital domain. Results also include a complete set of guidelines for final implementation of the CSC readout at CMS.
