Radiation Testing

Northrop Grumman’s Radiation Testing experts measure the effects of radiation on materials, devices, circuits and systems in natural and

man-made radiation environments. We perform characterization testing of electronics, from piece-parts to units, including performance response and radiation lot acceptance testing (RLAT). We support air and space programs with design assistance, test planning, execution, analysis, and performance verification. We design and fabricate custom fixtures for all radiation environments, and we can prepare samples for testing, including de-lidding and sample thinning. Also, we are licensed to handle radioactive materials.

Total Ionizing Dose (TID) TestingHigh-Dose Rate: Gammacell 220 sources available for standard dose rate testing. • MIL-STD-883 TM 1019, Condition A

Low-Dose Rate: Enhanced Low Dose Rate Sensitivity (ELDRS) Testing. Beacon and Shepherd sources available for low dose rate (0.01 rad(Si)/s).• MIL-STD-883 TM 1019, Condition D

Neutron Displacement Damage TestingAccess to neutrons from a TRIGA nuclear reactor for displacement damage testing.• MIL-STD-883 TM 1017

Prompt Dose Testing (Transient Radiation Effects on Electronics - TREE)Our Febetron 705 Flash X-ray Facility is used for upset, latch-up and burnout testing of electronic parts and circuits up to 1011 rad(Si)/s. • MIL-STD-883 TM 1020, 1021, 1023

Single Event Effects (SEE) TestingPlan experiments and prepare custom fixtures for Single Event Effects (SEE) testing. Custom portable test system available for proton and heavy ion testing at off-site facilities.Proton: Massachusetts General Hospital, UC-Davis Crocker Nuclear Lab, Lawrence Berkeley National Laboratory (LBNL) 88-inch CyclotronHeavy Ion: Texas A&M University Cyclotron Institute, Lawrence Berkeley National Laboratory (LBNL) 88-inch Cyclotron, and other accelerator sites.• ASTM F 1192-00(2006), EIA/JESD 57

Radiation Effects AnalysisEnsure system performance and survival in radiation environments.Perform circuit and unit-level radiation hardening and survivability analyses, such as radiation transport, derating, and PSPICE simulation.
