Impact of Register Reservation on the Reliability of Arm Cortex-M Processors under Neutrons

Leonardo Reinehr Gobatto, Fábio Benevenuti, Luiz Henrique Laurini, Benjamin Cheymol et autres

This paper investigates the impact of register reservation techniques on the radiation resilience of Arm Cortex-M7 microprocessors. Using a $32 \times 32$ matrix multiplication workload, we evaluate performance and reliability across several compilation configurations, focusing on standard compilation and versions reserving up …

Accurate measurements of delayed neutron data for reactor applications: methodology and application to 235U(nth,f)

Pierre Leconte, Dorian Belverge, David R. Bernard, A. Chebboubi et autres

Abstract Large inconsistencies still exist in nuclear data libraries regarding the kinetic parameters of delayed neutron (DN) precursors. As an example, there is a 17% gap between ENDF-B/VIII.0 and JEFF-3.3 on the average lifetime T1/2 of DN precursors from thermal fission of …

Beam Instrumentation, Challenging Tools for Demanding Projects –– a Snapshot from the French Assigned Network

F. Poirier, Thomas N Adam, P. Bambade, Sidi Mohammed Ben Abdillah et autres

Particle accelerators are thrusting the exploration of beam production towards several demanding territories, that is beam high intensity, high energy, short time and geometry precision or small size. Accelerators have thus more and more stringent characteristics that need to be measured. Beam …

Assessment of On-Chip Current Sensor for Detection of Thermal-Neutron-Induced Transients

Rodrigo Possamai Bastos, Jean-Max Dutertre, Matheus Garay Trindade, Raphael Viera et autres

This article assesses, for the first time, a body/bulk built-in current sensor (BBICS) in a CMOS 65-nm test chip under thermal neutron, high-energy neutron, and laser radiation. Experimental results suggest that the on-chip current sensor is effective to detect transient faults in …
