New Capabilities of the FLUKA Multi-Purpose Code

FLUKA is a general purpose Monte Carlo code able to describe the transport and interaction of any particle nucleus type in complex geometries over an energy range extending from thermal neutrons ultrarelativistic hadron collisions. It has many different applications accelerator design, detector studies, dosimetry, radiation protection, medical physics, space research. In 2019, CERN INFN, as copyright holders, together decided end their formal collaboration framework, allowing them henceforth pursue pathways aimed at meeting evolving requirements user community, ensuring long term sustainability code. To this end, set up FLUKA.CERN Collaboration 1 . This paper illustrates physics processes that have been newly released or are currently implemented distributed by 2 under new licensing conditions meant further facilitate access code, well intercomparisons. The description coherent effects experienced high beams crystal devices, relevant promising beam manipulation techniques, charged tracking vacuum regions subject electric field, overcoming former lack, already made available users. Other features, namely kinds low deuteron interactions synchrotron emission course magnetic fields, undergoing systematic testing benchmarking prior release. widely used evaluate radiobiological effects, with powerful support Flair graphical interface, whose generation (Available http://flair.cern ) offers now additional capabilities, e.g., advanced 3D visualization photorealistic rendering for industry-standard volume phantoms. also playing extensive role characterization environments which electronics operate. parallel, it response variety not included guidelines standards accelerators, accessible through conventional ground level testing. Instructive results obtained Single Event Effects (SEE) simulations benchmarks, when possible, various types energies. reached maturity, planning substantial evolution its present architecture. Moving towards modern programming language allows overcome fundamental constraints limited development options. Our goal, addition improving performances even more rigorous scientific oversight, modernize structure integrate independent contributions easily formalize quality assurance state-of-the-art software deployment techniques. includes continuous integration pipeline automatically validate codebase automatic processing analysis tailored physics-case test suite. With regard aforementioned objectives, several paths envisaged, like finding synergies Geant4, both core interface level, way offering possibility run same input codes crosscheck results.
