/ Gabrisch, Lukas (Oldenburg U.) ; Cecchetto, Matteo (CERN) ; Delfs, Björn (Oldenburg U.) ; Looe, Hui Khee (Oldenburg U.) ; Budroweit, Jan (DLR, Bremen) ; Alía, Rubén García (CERN) ; Poppe, Björn (Oldenburg U.) ; Wyrwoll, Vanessa (Oldenburg U.)
The possibility of using calibrated static random-access memory (SRAM) memory for the quantification of neutron fluence in a radiotherapy facility for cancer treatment utilizing a high-energy 15-MV photon beam (Bremsstrahlung) from an electron linear accelerator has been exploited in this work. This has been performed by varying the field size of the photon beam and the positioning of the SRAM memory at three different positions in relation to the isocenter of the beam. [...]

U.) ; Cecchetto, Matteo (CERN) ; Gilardi, Antonio (CERN ; Naples U. ; LBNL, Berkeley) ; Farabolini, Wilfrid (CERN ; Saclay) ; Corsini, Roberto (CERN)
We study the radiation environment near the terahertz (THz) dump of the CERN Linear Electron Accelerator for Research (CLEAR) electron accelerator at CERN, using FLUktuierende KAskade in German (FLUKA) simulations and single-event upset (SEU) measurements taken with 32-Mbit Integrated Silicon Solution Inc. (ISSI) static random access memories (SRAMs). [...]

Analysis of the Radiation Field Generated by 200-MeV Electrons on a Target at the CLEAR Accelerator at CERN
/ Lerner, Giuseppe (CERN) ; Pelissou, Pierre (CERN ; INSA, Toulouse) ; Aguiar, Ygor Q (CERN) ; Sacristan Barbero, Mario (CERN) ; Cecchetto, Matteo (CERN) ; Biłko, Kacper (CERN) ; Coussen, Louise (CERN ; INSA, Toulouse) ; Emriskova, Natalia (CERN) ; García Alía, Rubén (CERN) ; Dyks, Luke (CERN ; Oxford U.) et al.
The radiation showers generated by the interaction of high-energy electrons with matter include neutrons with an energy distribution peaked at the MeV scale, produced via photonuclear reactions, allowing measurements of neutron-induced single-event effects (SEEs) in electronic devices. In this work, we study a setup where the 200-MeV electron beam of the CLEAR accelerator at European Organization for Nuclear Research [Centre Européen pour la Recherche Nucléaire (CERN)] is directed on an aluminum target to produce a radiation field with a large neutron component.

Thermal Neutron-Induced SEUs in the LHC Accelerator Environment
/ Cecchetto, Matteo (CERN) ; García Alía, Rubén (CERN) ; Wrobel, Frédéric (IES, Montpellier) ; Tali, Maris (CERN) ; Stein, Oliver (CERN) ; Lerner, Giuseppe (CERN) ; Biłko, Kacper (CERN) ; Esposito, Luigi (CERN) ; Bahamonde Castro, Cristina (CERN) ; Kadi, Yacine (CERN) et al.
In addition to high-energy hadrons, which include neutrons, protons, and pions above 20 MeV, thermal neutrons (ThNs) are a major concern in terms of soft error rate (SER) for electronics operating in the large hadron collider (LHC) accelerator at the European Organization for Nuclear Research (CERN). Most of the electronic devices still contain Boron-10 inside their structure, which makes them sensitive to ThNs. [...]

Electronics Irradiation With Neutrons at the NEAR Station of the n_TOF Spallation Source at CERN

We study the neutron field at the NEAR station of the neutron time-of-flight (n_TOF) facility at CERN, through Monte Carlo simulations, well-characterized static random access memories (SRAMs), and radio-photoluminescence (RPL) dosimeters, with the aim of providing neutrons for electronics irradiation. Particle fluxes and typical quantities relevant for electronics testing were simulated for several test positions at NEAR and compared to those at the CERN high-energy accelerator mixed-field facility (CHARM), highlighting similitudes and differences.

We have performed real-time soft error rate (RT-SER) measurements on bulk 65-nm static random access memories (SRAMs) during deuterium-deuterium (D-D) plasma operation at W-tungsten–Environment in Steady-state Tokamak (WEST). The present measurement campaign was characterized by the production of several tens of long pulse discharges (~60 s) and by a total neutron fluence (at the level of the circuits under test) up to ~$10^9$ n$\cdot$cm$^2$ , improving the error statistics by a factor of more than 6 with respect to the first measurements obtained in 2020.

An Analysis of the Significance of the 14N(n, p) 14C Reaction for Single-Event Upsets Induced by Thermal Neutrons in SRAMs

The thermal neutron threat to the reliability of electronic devices caused by $^{10}\text{B}$ capture is a recognized issue that prompted changes in the manufacturing process of electronic devices with the aim of limiting as much as possible the presence of this isotope nearby device sensitive volumes (SVs). $^{14}\text{N}$ can also capture thermal neutrons and release low-energy protons (LEPs; through the $^{14}\text{N}$ (n, p) $^{14}\text{C}$ reaction) that have high enough linear energy transfer (LET) to cause single-event upsets (SEUs).
