    1. A gamma ray enters the LAT. It first passes through the Anticoincidence Detector without producing a signal.
    2. The gamma ray interacts in one of 16 thin tungsten sheets. This interaction converts the gamma ray into an electron and a positron via pair production (governed by Einstein’s equation E=mc2).
    3 The Tracker uses silicon strips to measure the paths of the electron and positron, allowing the LAT to determine the arrival direction of the gamma ray.
    4. The electron and positron enter the Calorimeter, which measures the energies of the particles, and therefore the energy of the original gamma ray.
