Description

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, built by correlating clusters in two closely spaced
sensor layers for the rejection of hits from low transverse momentum tracks,
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 momentum above 3 GeV/c by building tracks
out of stubs. A concept for an FPGA-based track finder using a fully
time-multiplexed architecture is presented, where track candidates are
identified using a projective binning algorithm based on the Hough
Transform. A hardware system based on the MP7 MicroTCA processing card
has been assembled, demonstrating a realistic slice of the track finder
in order to help gauge the performance and requirements for a full system.
This poster outlines the system architecture and algorithms employed,
highlighting some of the first results from the hardware demonstrator
and discusses the prospects and performance of the completed track finder.
