Open-source engineering tools, curated data, and a community forum for space radiation effects professionals. Plan tests, analyze data, and connect with fellow engineers.
Free, browser-based tools for radiation effects analysis. No login required.
Fit Weibull curves to heavy-ion cross-section data, estimate proton SEE rates using the Edmonds method, and export publication-ready plots and PDF reports.
Launch Tool →Look up proton NIEL for 10 materials, convert fluence between energies, calculate displacement damage dose, and compute 1 MeV neutron equivalents.
Launch Tool →Enter a part number to get device-specific radiation effects guidance covering TID risk, SEE susceptibility, displacement damage, derating rules, and design tips.
Launch Tool →Plan heavy-ion SEE tests: define your device overlayers, set LET and range requirements, and find matching beams across TAMU, LBNL, BNL, MSU, and RADEF.
Launch Tool →Radiation Effects Data Workshop cross-section distributions for common device families, compiled from decades of published NSREC and RADECS data.
View Data →Convert beam current to flux and ionizing dose rate for proton testing in silicon. Bethe–Bloch LET with optional custom table override and facility presets.
Launch Tool →Compute in-flight SEE rates via spectral integration with CREME96/OMERE environments. Supports heavy-ion and proton rates, Ladbury SEL bounding, and PDF reports.
Launch Tool →Whether you're new to RHA or a seasoned practitioner, explore topics across the discipline.
Heavy-ion test planning, facility selection, Weibull fitting, rate prediction with CREME96, and the LET(Si) vs. LET(material) debate.
Discuss →ELDRS testing strategies, radiation design margin practices, Co-60 test methods, and the dose rate acceleration debate.
Discuss →NIEL scaling, proton energy selection, optical component characterization, and when displacement damage dose predictions break down.
Discuss →COTS part risk assessment, lot-to-lot variability, rad-hard vs. mitigation trades, and getting through a parts review board.
Discuss →The Space RHA forum is an open space for radiation effects engineers, researchers, and program managers. Ask questions, share experience, and help others navigate RHA challenges.
Topics span heavy-ion test planning, ELDRS testing, NIEL scaling, COTS qualification, and everything in between. Whether you're a seasoned practitioner or just getting started, there's a place for you.
