The FLUKA Monte Carlo code is widely used at CERN for beam-machine interactions, radioprotection calculations, and facility design. It is also a core tool for hadron-therapy facilities in Europe. Medical applications require high reliability and predictive power, necessitating continuous refinement of nuclear models and code improvements. Recent developments in FLUKA include enhanced modeling of hadronic interactions, particularly for low mass chains, which improve predictions for neutrino interactions and single pion production in neutrino reactions. These improvements are crucial for neutrino beam design and medical applications. FLUKA is also used for designing neutrino facilities like CENF for sterile neutrino detection. The code's accuracy in meson production is validated against experimental data, showing good agreement. For hadron therapy monitoring, FLUKA has been enhanced to better predict reactions important for PET monitoring, such as (p,x) reactions. Additionally, FLUKA now incorporates spin and parity effects in nuclear de-excitation, improving the accuracy of reaction predictions. The code is used for various applications, including neutrino beams, underground experiments, and medical applications. Recent improvements in FLUKA have enhanced its predictive power and accuracy, particularly in modeling low mass chains and spin/parity effects. The code is supported by the European Laboratory for Particle Physics (CERN) and the Italian National Institute for Nuclear Physics (INFN).The FLUKA Monte Carlo code is widely used at CERN for beam-machine interactions, radioprotection calculations, and facility design.
