Trigger level track reconstruction in CMS with a fully time-multiplexed architecture using a Hough transform implemented in an FPGA

Exploring foci of: Proceedings of 38th International Conference on High Energy Physics — PoS(ICHEP2016) Trigger level track reconstruction in CMS with a fully time-multiplexed architecture using a Hough transform implemented in an FPGA February 2017 • L. Calligaris A new tracking system is under development for operation in the CMS experiment at the High Luminosity LHC. It includes an outer tracker which will construct ``stubs'' -- pairs of hits built by correlating clusters measured in two closely spaced silicon sensor layers -- and transmit them off-detector at 40 MHz. If tracker data is to contribute to keeping the Level-1 trigger rate at around 750 kHz under increased luminosity, a crucial component of the upgrade will be the ability to identify tracks with transverse mo… Open Article Page
