Understanding particle acceleration up to very high energies in the Universe requires Earth-bound experimental techniques that exploit the Earth’s atmosphere as detection medium. Only the shear size of the atmosphere provides a sufficiently large sensitive area to measure the very rare highest energy particles from the cosmos as they impinge on the Earth. The idea of the atmospheric measurement is simple: a cosmic particle hitting the atmosphere is being absorbed by developing into an air shower, a spray of secondary particles that originates in the collision of the primary cosmic particle with air molecules, and successive interactions of those secondary particles in the atmosphere. Such air showers can be traced and therefore measured on Earth, providing information about the energy, type, and direction of the primary cosmic particle, by different means. Important examples of such atmospheric detection techniques include the measurement of muons with particle counters at the Earth’s surface and the measurement of Cherenkov or Fluorescence light emitted during the air shower development. The connection between measured quantities like particle numbers or light intensity and original quantities like particle energy or type is in all cases inferred using simulations of particle collisions and cascades in the atmosphere.

The goal of this master project is to exploit data of proton collisions measured with ATLAS, an experiment at the Large Hadron Collider (LHC), the highest energy human particle collider currently operating at CERN in Geneva (Switzerland), to test and improve simulations of particle collisions in the atmosphere up to the highest known energies (a few times 1020 eV). The student will work on ATLAS data analysis and Monte Carlo simulations of particle collisions, both for simulating proton colliding in ATLAS and cosmic-ray protons colliding with air molecules in the atmosphere. The ultimate goal is to improve Monte Carlo model predictions used for experiments like the [http://www.cta-observatory.org/ upcoming CTA] and [http://www.auger.org/ Auger].

CERN plans to upgrade the LHC to provide a significantly higher luminosity around 2025. This will affect the ATLAS detector, and ATLAS is designing a new inner tracker in order to cope with the significant challenges associated to the high-luminosity LHC. The Nikhef ATLAS group is working on the detector layout, and designing a new endcap silicon strip detector. We have projects in Geant4 detector simulation, silicon sensor development, CO2 cooling, Helium gas cooling, and carbon fibre composites.

The Nikhef ATLAS group is working on the detector layout, and designing a new silicon strip detector. In mutual discussions we can define a project that will involve either simulations, or hardware activities.
