Description
The Beam Radiation Instrumentation and Luminosity (BRIL) project is crucial for the CMS experiment at the LHC, aiming to provide the most precise luminosity measurements possible.
This involves the development, deployment, and operation of cutting-edge instrumentation, including the Pixel Luminosity Telescope (PLT).
The PLT consists of 16 telescopes, with each telescope featuring three planes of silicon pixel detectors designed to detect particles originating from the interaction point. The instantaneous luminosity is determined online by counting the rate of triple coincidences using a specialized "fast-or" readout mode on the pixel readout chip. The technology is based on the vertex detector of CMS, and includes HL-LHC upgrade sensors. The detectors are situated close to the LHC beam pipe, and together with sensors that monitor the beam conditions, some are made of sapphire and diamond.
Several studies will be presented on the reduction of background contributions based on track reconstruction and the impact of radiation damage on detector performance.
