The ATLAS detector has been designed for operation at CERN's Large Hadron Collider. ATLAS includes a complex system of liquid argon calorimeters. The electronics for amplifying, shaping, sampling, pipelining, and digitizing the calorimeter signals is implemented on the Front End Boards (FEBs). This paper describes the design, implementation and production of the FEBs and presents measurement results from testing performed at several stages during the production process.
A 0.25µm CMOS serializer ASIC, designed using radiation tolerant layout practice, was exposed to proton beam at various flux levels and accumulated fluence over 1.9×10 15 protons/cm 2 (100 Mrad (Si)). The ASIC survived this total ionizing dose (TID) with no degradation in function. Single event effect (SEE) cross-sections are also calculated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
