Honors Thesis


Particle physics uses powerful particle colliders to investigate building blocks of the universe that we would otherwise be unable to inspect. This research consists of developing the ATLAS Forward Proton (AFP) system intended for installation at the ATLAS experiment at the Large Hadron Collider (LHC) in Geneva, Switzerland. The AFP system includes a time-of-flight (TOF) detector specifically designed for the measurement of a certain class of collision events which have been heretofore largely invisible to the ATLAS experiment. We use the TOF of protons which pass through our detector to correlate them with a collision in the central ATLAS detector. ATLAS can then use these correlations to reject background events during data readout and improve overall efficiency. However, our detector must fit into a compact space in order to interface with the LHC. I present simulated designs that allow our detector to be compact and demonstrate the detector's expected performance.
