Description
We will describe the Pixel Luminosity Telescopes (PLT) dedicated luminosity monitor for CMS based on single-crystal diamond pixel telescopes. The PLT is comprised of an array of small-angle telescopes on each end of the CMS detector that point back to the collision point. Each telescope consists of three planes of single-crystal diamond pixel sensors bump-bonded to the CMS PSI46v2 pixel readout chip. The PLT is designed to measure the relative bunch-by-bunch luminosity in CMS to a precision of 1% on the time scale of a few seconds. We will present the simulated design performance capability of the PLT and describe its innovative use of single-crystal diamond sensors that provide the required radiation hardness and efficiency stability. We will also present the results of a test beam study of a prototype PLT telescope including occupancy, efficiencies, pulse height distributions and tracking capability.
