The radiation showers generated by the interaction of high-energy electrons with matter include neutrons an energy distribution peaked at MeV scale, produced via photonuclear reactions, allowing measurements neutron-induced Single-Event Effects in electronic devices. In this work we study a setup where 200-MeV electron beam CLEAR accelerator CERN is directed on aluminum target to produce field large neutron component. resulting environment analyzed measuring Upset (SEU) and Latchup rates...
We study the neutron field at NEAR station of time flight (n_TOF) facility CERN, through Monte Carlo simulations, well-characterized static random access memories (SRAMs) and radio-photo-luminescence (RPL) dosimeters, with aim providing neutrons for electronics irradiation. Particle fluxes typical quantities relevant testing were simulated several test positions compared to those CERN high energy accelerator mixed-field (CHARM), highlighting similitudes differences. The SRAM detectors, based...
Very-high-energy (VHE), heavy ions are of particular interest for single event effects testing due to their combination high linear energy transfer (LET) and penetration within electronics components. The dosimetry such beams poses an important challenge facilities aiming provide VHE radiation testing. In this paper, ion beam using a silicon solid state detector is presented uranium in the 100 – 1000 MeV per nucleon kinetic range. study involves experimental measurements carried out at SIS18...
A critical step of radiation hardness assurance (RHA) for space systems is given by the parts selection in accordance with observed (or estimated) effects. Although testing most decisive way studying degradation electronic components, increasing use commercial off-the-shelf (COTS) devices and challenges posed <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">NewSpace</i> are pushing need finding new approaches to assess risk associated...
This paper investigates an application of the 1000µm-thick silicon solid-state detector for monitoring a mixed-field radiation environment, in particular accelerator environment. The calibrations against both alpha source and high-energy protons are presented. measurements benchmarked FLUKA Monte Carlo simulations. As might be deployed future RadMON version, simulated use case is presented, highlighting enhanced sensitivity (by 3-4 orders magnitude) with respect to SRAM-based solutions, High...
We present a calibration of commercial silicon diode with proton and alpha beams gamma rays.The together fast acquisition chain can be exploited for both direct indirect (through the secondary radiation field) beam characterization.Within this work, we demonstrate detector capabilities resolving single-energy-deposition events independently measuring dose rate flux.Profiting from mixed field in CERN's high-energy accelerator facility (CHARM) show how to characterize it, which turn is used...
Ultra-high energy (> 5 GeV/n) heavy ion beams exhibit different properties when compared to standard and high beams. Most notably, fragmentation is a fundamental feature of the beam that may have important implications for electronics testing given ultra-high energies, hence ranges, preserved by fragments. In this work, both primary lead beam, available in CERN North Area, its fragments are characterized means solid-state detectors. This input later used improve measurements Single Event...
The FLUKA Monte Carlo code has recently undergone significant enhancements, driven by needs from its user community. Key improvements are discussed, such as a new point-wise treatment for the interactions of low-energy neutrons, incorporation model nuclear elastic scattering protons below 250 MeV, explicit generation synchrotron radiation photons during charged particle tracking, revised modeling approach coherent effects in bent crystals, and addition arc-DPA scoring. While improving...
A successful predictive analysis, based on archival data, for one bipolar operational amplifier is presented in this work. The model has been evaluated crosschecking with the results from new TID and DD radiation test campaigns.
We present applications of a large commercial silicon diode (50 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> x 500 um) for monitoring low-intensity radiation fields, together with benchmarks via Monte Carlo simulations. After the energy calibration monoenergetic proton and alpha beams in 2-8 MeV range, we show that detector is capable measuring atmospheric at ground level, not only terms total number events but also through their...
