“…high Q crit with high-Z material near the SV in the hadron energy range from 200 MeV to 3 GeV due to fission reactions [33] and the impact of directly ionizing light charged particles such as protons [34] and muons [35]. Additional studies investigated SEEs induced by electro-and photonuclear reactions [36] and, via a Geant4-based extension, by neutrons in the 0.1-10 MeV neutron range [37].…”

FLUKA is a general purpose Monte Carlo code able to describe the transport and interaction of any particle and nucleus type in complex geometries over an energy range extending from thermal neutrons to ultrarelativistic hadron collisions. It has many different applications in accelerator design, detector studies, dosimetry, radiation protection, medical physics, and space research. In 2019, CERN and INFN, as FLUKA copyright holders, together decided to end their formal collaboration framework, allowing them henceforth to pursue different pathways aimed at meeting the evolving requirements of the FLUKA user community, and at ensuring the long term sustainability of the code. To this end, CERN set up the FLUKA.CERN Collaboration1. This paper illustrates the physics processes that have been newly released or are currently implemented in the code distributed by the FLUKA.CERN Collaboration2 under new licensing conditions that are meant to further facilitate access to the code, as well as intercomparisons. The description of coherent effects experienced by high energy hadron beams in crystal devices, relevant to promising beam manipulation techniques, and the charged particle tracking in vacuum regions subject to an electric field, overcoming a former lack, have already been made available to the users. Other features, namely the different kinds of low energy deuteron interactions as well as the synchrotron radiation emission in the course of charged particle transport in vacuum regions subject to magnetic fields, are currently undergoing systematic testing and benchmarking prior to release. FLUKA is widely used to evaluate radiobiological effects, with the powerful support of the Flair graphical interface, whose new generation (Available at http://flair.cern) offers now additional capabilities, e.g., advanced 3D visualization with photorealistic rendering and support for industry-standard volume visualization of medical phantoms. FLUKA has also been playing an extensive role in the characterization of radiation environments in which electronics operate. In parallel, it has been used to evaluate the response of electronics to a variety of conditions not included in radiation testing guidelines and standards for space and accelerators, and not accessible through conventional ground level testing. Instructive results have been obtained from Single Event Effects (SEE) simulations and benchmarks, when possible, for various radiation types and energies. The code has reached a high level of maturity, from which the FLUKA.CERN Collaboration is planning a substantial evolution of its present architecture. Moving towards a modern programming language allows to overcome fundamental constraints that limited development options. Our long term goal, in addition to improving and extending its physics performances with even more rigorous scientific oversight, is to modernize its structure to integrate independent contributions more easily and to formalize quality assurance through state-of-the-art software deployment techniques. This includes a continuous integration pipeline to automatically validate the codebase as well as automatic processing and analysis of a tailored physics-case test suite. With regard to the aforementioned objectives, several paths are currently envisaged, like finding synergies with Geant4, both at the core structure and interface level, this way offering the user the possibility to run with the same input different Monte Carlo codes and crosscheck the results.

“…The CERN Linear Electron Accelerator for Research (CLEAR) [1] provides electron beams with energies in the 55-220 MeV range, allowing access from both CERN and external users for many applications. In the context of radiation effects to electronics (R2E), direct in-beam irradiations at CLEAR have been used to show that high-energy electrons can induce Single Event Upsets (SEUs) [2], latchups [3] and stuck bits [4] in memories. This work analyses the radiation field in off-beam positions near the beam dump of one of the CLEAR test stations, TeraHertz (THz), with focus on neutrons generated via photonuclear reactions in the dump block, that are capable of inducing SEUs in sensitive devices via indirect ionisation [5].…”

We study the radiation environment near the THz dump of the CLEAR electron accelerator at CERN, using FLUKA simulations and Single Event Upset measurements taken with 32 Mbit ISSI SRAM memories. The main focus is on the characterisation of the neutron field, to evaluate its suitability for radiation tests of electronics in comparison with other irradiation facilities. Neutrons at CLEAR are produced via photonuclear reactions, mostly initiated by photons from the electromagnetic cascades that occur when the beam is absorbed by the dump structure. Good agreement is generally found between the measured SEU rates and the expected values obtained from FLUKA simulations and from the known SEU response of the ISSI SRAMs to neutrons, while one position is found to be potentially affected by photon-driven SEUs.
