“…Recently, deuteron transport has gained increased attention, for applications as diverse as the production of radioisotopes for medical applications using deuteron beams [12,13], their radiobiological effects and associated radiation protection aspects [14], as well as for nuclear fusion studies [15]. Furthermore, deuteron production from hadron-and nucleusnucleus inelastic interactions is often far from negligible; an accurate description of their subsequent nuclear interactions is necessary.…”

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 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.

“…During the commissioning of the Linear IFMIF Prototype Accelerator (LIPAc) [1], an intense study campaign focused on the injector, composed by the ECR ion source and the LEBT line [2] has been perfomed, in order to characterize the beam at the RFQ input and to reach its nominal transmission (achieved in 2019 [3]). The experiments related to the injector are described in [4,5]. The ECR (Electron Cyclotron Resonance) consists of a 2.45 GHz RF power source with two coils magnetic structure.…”

The Linear IFMIF Prototype Accelerator (LIPAc) is a high intensity D+ linear accelerator; demonstrator of the International Fusion Material Irradiation Facility (IFMIF). In summer 2019 the IFMIF/EVEDA Radio Frequency Quadrupole (RFQ) accelerated its nominal 125 mA deuteron (D+) beam current up to 5 MeV, with 90% transmission for pulses of 1 ms at 1 Hz. This success was possible thanks to an intense previous campaign of modelization and measurements in order to characterize the RFQ input beam, which is affected by the ECR ion source extraction and the low energy beam transport. The simulation models used with the measurement benchmarks are here presented.

“…The ECR ion source and pre-analysis system are designed to provide and transport 35 mA and 50 keV CW D + 1 beams for neutron production, and 50 mA and 50 keV CW proton beams for commissioning. The commonly used scheme for the low-energy transmission line of a high-current ion beam features a combination of double solenoids (such as IFMIF [6] and ESS [7]). The beam line of this combination of double solenoids is short, and can be used to control the increase in emissivity.…”

An intense accelerator-based D-D/D-T neutron generator, with neutron yields of 6 × 10 10 n/s due to the D-D reaction and 6 × 10 12 n/s due to the D-T reaction, is being developed at Lanzhou University in China. The 2.45 GHz electron cyclotron resonance (ECR) ion source and the pre-analysis system, as the front injector for the accelerator tube of the neutron generator, are designed to provide a 35 mA deuterium beam for neutron production and a 50 mA proton beam for commissioning. The pre-analysis system consists of a solenoid, a steering magnet, a vacuum chamber, a dipole magnet, three quadrupole magnets, a beam dump, and a Faraday cup. The ion source and pre-analysis system were completed a trial operation, and the intensity of the proton beam measured at the end of the pre-analysis system was higher than 50 mA when the hydrogen ion beam current extracted from the ECR ion source was greater than 70 mA.
