SOI microdosimeter and TimePix responses were compared behind aluminium shielding of varying thicknesses to simulate astronaut exposure using 290MeV/u 12C, 400MeV/u Ne, 800MeV/u 28Si, and 650MeV/u 40Ar ions. Good agreement was observed.

Temperature Calibration of Radioluminescent Pure Silica Core Fiber Based Dosimeters for Space Applications

S. Acid^1,2, A. Morana², I. Zghari³, M. Aubry⁴, N. Kerboub¹, J. Guillermin⁴, J. Mekki¹, Y. Ouerdane², M. Darnon², H. El Hamzaoui³, B. Capoen³, M. Bouazaoui³, A. Boukenter², S. Girard²

1. CNES, France   2. Université de Saint Etienne, France   3. Université de Lille, France   4. TRAD, France

We demonstrate temperature calibrated radioluminescent dosimetry using pre-irradiated pure silica core optical fibers, achieving stable real-time dose-rate measurements under coupled temperature and dose-rate variations, with mean errors below 1.5%, validating feasibility for space radiation monitoring.

Commercial Solid-State Detectors for Identifying Pulsed-Laser Operating Parameters for Surrogate SEE Testing

J. Hales¹, A. Ildefonso², T. Crane¹, A. Khachatrian¹, D. McMorrow¹

1. US Naval Research Laboratory, USA   2. Indiana University Bloomington, USA

This work identifies solid-state detectors that exhibit transient responses which are strongly dependent on pulsed-laser operating parameters. Such standardized reference detectors are important for providing repeatability and traceability in surrogate single- event effects testing.

F. Fricano¹, A. Morana², Y. Ouerdane², D. Lambert¹, P. Paillet¹, S. Girard²

1. CEA/CESTA, France   2. Université de Saint Etienne, France

The influence of fibers with different hydroxyl (OH) group contents, commonly used as transport fibers in dosimetry systems based on the radioluminescence of scintillating optical fibers, such as Ce3+-doped fibers, is evaluated.

Dual-Reference-Level Inversion for High-Linearity In-Situ Radiation Dosimetry in 3D NAND Flash

M. Dong¹, W. Chen¹, Z. Zhang¹, Y. Ouyang¹, L. Cai¹

1. Sun Yat-sen University, China

This work demonstrates a high-linearity radiation dosimeter using commercial 3D NAND. The dual-reference-level sampling technique achieves linearity above 0.9867 up to 35 krad(Si) with 3.0% maximum relative error, enabling accurate in-situ monitoring for aerospace applications.

M. Kumar¹, J. Bell¹, A. Brandl¹, B. Ray¹

1. Colorado State University, USA

This work experimentally investigates 3-D floating-gate and charge-trap NAND flash as passive radiation dosimeters, showing linear FG sensitivity of ~12.5 mV/krad(Si), while CT exhibits multi-mechanism, non-linear response with ~35 mV/krad(Si) initially, reducing to ~18 mV/krad(Si).

This paper presents a time-resolved, measurement-driven approach to estimate SEU rates in spacecraft memories during SPEs by reconstructing particle spectra from GOES-16 and ACE flux measurements. The method is validated against in-flight upset-count data from RHEME-3.
