Abstract:A: The phase-2 upgrade of the LHC will require novel pixel readout chips, which deliver hit information at drastically increased data rates and tolerate unprecedented radiation levels. The large-scale prototype chip RD53A has been designed by the RD53 collaboration and manufactured in a 65 nm CMOS process, suitable for the innermost layers of both the ATLAS and the CMS experiment. In order to verify the radiation hardness design goal of 500 Mrad total ionizing dose, RD53A has been irradiated using X-rays. The … Show more
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.
