F-1

Displacement Damage Dose Analysis for Solar Cells in a Jovian Radiation Environment
J. Warner, Johns Hopkins Applied Physics Laboratory, USA, L. Martinez-Sierra, I. Jun, NASA-JPL, USA

The displacement damage dose (DDD) analysis for solar cells operating in a Jovian combined particle radiation environment, specifically Europa Clipper Mission, is presented. The importance of DDD calculations as a function of shielding are discussed.

F-2

1-10 MeV Neutron SER in Accelerator and Atmospheric Environments
M. Cecchetto, R. Garcia Alia, A. Coronetti, CERN, Switzerland, F. Wrobel, University of Montpellier 2, France S. Fiore, G. Bazzano, ENEA Frascati, Italy

Low-energy neutrons between 1-10 MeV can significantly impact the SER in scaled technologies, down to 40 nm SRAMs, with respect to high-energy neutrons. Their contribution is evaluated in accelerator and ground level environments.

PF-1

Neutron Environment at High-Altitude High-Performance Computing Facilities
S. Nowicki, E. Mullin, L. Ferres, S. Blanchard, N. Debardeleben, S. Wender, G. McMath, G. McKinney, Los Alamos National Laboratory, USA

Cosmic-ray induced neutrons can have large effects on computing systems when they interact with the electronics. In an effort to monitor the neutron environment in the LANL high-performance computing facility, we have deployed neutron detectors.

PF-2

Hybrid Shielding Configuration for Sensitive Space Electronics Subjected to Extreme Space Weather
R. Pal Chowdhury, L. Stegeman, A. Bahadori, Kansas State University, USA, M. Lund, University of Utah, USA, D. Fry, NASA-Johnson, USA, S. Madzunkov, NASA-JPL, USA

In this study, a novel hybrid radiation shielding configuration is proposed. The efficacy of this configuration in terms of protecting space-based electronics against extreme solar weather and the reduction of mass-penalty is analyzed.

PF-3

The Compact Environmental Anomaly Sensor Risk Reduction (CEASE-RR): On-Orbit Measurements
C. Lindstrom, D. Barton, E. Friedman, Air Force Research Laboratory, USA, K. Greene, University of New Mexico (COSMIAC), USA

CEASE RR is a new compact sensor designed for anomaly attribution due to the space radiation environment launched in April 2018. Cross-comparison campaigns with GOES are presented, and inner Van Allen belt measurements during ascent.

PF-4

Jason-2 Measurements Compared with AP9 (v. 1.50.001) & AP8
C. Lindstrom, A. Andersen, J. Insoo, NASA-JPL USA

AP9 (also known as IRENE) version 1.50.001 is compared to Jason-2 measurements. It is shown that the measurements are in better agreement than previous comparisons with version 1.20 of the AP9 model.
