FLUKA

Also known as FLUktuierende KAskade

FLUKA (an acronym for Fluktuierende Kaskade) is a fully integrated Monte Carlo simulation package for the interaction and transport of particles and nuclei in matter. FLUKA has many applications in particle physics, high energy experimental physics and engineering, shielding, detector and telescope design, cosmic ray studies, dosimetry, medical physics, radiobiology. A recent line of development concerns hadron therapy. As of 2022 FLUKA allowed simulation of interactions of photons with energy 100 eV and above.
