Summary
The internship project is to study and characterize the response function of the chip. To achieve this goal, the chosen student will learn to use a GEANT4 simulation reproducing the experimental setup used during the beam tests made at CERN. The student will then test and implement several models for the chip response function and compare them to data.
Full description
The LHCb detector is one of the four major detectors installed on the Large Hadron Collider (LHC) at CERN. Designed to study heavy-quark production in proton-proton collisions, the detector will undergo a major upgrade in 2030 of all its sub-detectors. Among them, the Upstream Tracker (UT), a four-station tracker installed upstream of the LHCb magnet, is crucial to distinguish fake reconstructed tracks from good ones, especially in collisions with high particle multiplicity (or high pileup), such as heavy-ion collisions.
Currently using silicon strip detectors, the UT will have to be rebuilt using silicon pixel chips to cope with the high collision rate foreseen at the LHC in 2030. The choice of pixel technology is not settled, and studies based on simulation are required to compare the different options. The chip response function is a key ingredient, which can be characterized based on GEANT4 simulations and databases from beam tests made at the CERN. This response function is mandatory for performance studies and ultimately for choosing UT’s future technology.
