Zero-G Radiation Assurance
EXPERTISE
COMPONENT EVALUATION
A quality BOM review process is key for any mission in a space or nuclear environment. We have decades of experience with various mission types & EEE parts requirements, from NASA Class A to Class D and CubeSat missions. We leverage our internally developed radiation database to provide up-to-date information and assessment from experienced subject matter experts. We will also have discussions with your designers to understand application-specific performance, provide mitigation techniques, and recommend potential alternative components to meet your specific requirements. We also support parts engineering activities:
-
Evaluate EEE parts against program requirements (e.g. Screening, Qualification, and DPA)
-
Create detailed part drawings to meet program requirements
-
Review Non-Standard Part Approval Requests (NSPAR’s)
-
Review GIDEP Advisories and Alerts to determine program impact
-
Manage Program Approved Parts Lists (PAPL’s)
Standards that we often work with:
Note - The standards are periodically revised and updated. Be sure to check with the appropriate government agency for the latest document revision.
ENVIRONMENT DERIVATION
Simulate mission's radiation environment, including:
-
Total-ionizing dose profile
-
Displacement damage dose
-
Trapped proton & electron flux
-
Galactic cosmic ray heavy ion LET spectra
-
Worst-case solar particle spectra
-
and More
Here is an example of the dose profile for a LEO mission. The total mission dose is given as a function of the spacecraft shielding thickness. Additionally, the plot shows the individual dose contributions from various particle sources. We see the dominant contribution from solar protons for this mission.
We will also determine the adequate radiation requirements based on your mission needs, leveraging on our experience writing radiation requirement documents for NASA missions and commercial space launch vehicle programs.
RADIATION TESTING
Radiation sources and tests we support:
-
SEE testing (heavy ion, proton, laser, etc.)
-
TID testing (Co-60 gamma rays)
-
MIL-STD-883 TM 1019 Condition A, B, C, D

RADIATION ANALYSIS
Types of analysis we commonly perform:
-
SEE rate calculation using industry standard CREME96, OMERE
-
SEU / SET data analysis and characterization
-
TID delta-parameter characterization, KTL limits
Run your analysis efficiently with our in-house developed SEE analysis app. Instantly calculate Figure-of-Merit SEU rates from heavy ion and proton test data. For proton data, the tool calculates rates from a set of mission parameters including orbit inputs, solar condition, and shielding level. Our SEE analysis app is free to use for the community.
