A study of the LHCb mighty tracker concept for upgrade 2 — •Hannah Schmitz, Klaas Padeken, and Sebastian Neubert for the LHCb collaboration — Rheinische Friedrich-Wilhelms Universität Bonn
After the HL-LHC upgrade in long shutdown 4 the instantaneous luminosity of the HL-LHC is up to 1.5· 1034 cm−2s−1 at point 8.
Therefore, the LHCb tracking system has to be upgraded. The three tracking stations of its downstream tracking spectrometer are thus studied with focus on a hybrid detector technology, where silicon pixels and scintillating fibres are installed in one module. This is known as the mighty tracker.
During long shutdown 3 (upgrade 1b) the inner part (3.9 m2) of the tracking stations is planned to be replaced by a silicon pixel detector, surrounded by scintillating fibres in the outer part, to cover the region of highest particle density. The pixels are based on HV-CMOS technology and have a size up to
100 µ m × 500 µ m. In upgrade 2 the silicon part is planned to be expanded up to a size of 18.1 m2 in total.
This presentation covers first results of the mighty pixel studies and plans for the mighty tracking detector.
