Northrop Grumman Demonstrates Secure Radiation Testing for Microelectronics

2026/01/21 08:59:35 – northrop Grumman has successfully demonstrated a secure testing surroundings for microelectronics exposed to radiation, a significant step forward in ensuring the reliability of critical systems in space and other harsh environments. This achievement is a direct result of the company’s work under the Defense Advanced Research Projects Agency’s (DARPA) Advanced Sources for Single-event Effects Radiation Testing (ASSERT) program,announced on January 13,2026.

the Challenge of Radiation Hardening

Modern electronics are increasingly vulnerable to radiation, especially in space-based applications. High-energy particles can disrupt the flow of electricity within microchips, causing errors or even permanent damage. These disruptions, known as single-event effects (SEEs), can lead to malfunctions in satellites, spacecraft, and even terrestrial systems exposed to radiation from solar flares or nuclear events. DARPA’s ASSERT program recognizes this growing threat and aims to develop more accessible and efficient methods for testing and mitigating these effects.

What is DARPA’s ASSERT Program?

Traditionally, testing microelectronics for radiation hardness has required access to large, expensive, and often geographically limited heavy-ion test facilities. These facilities use particle accelerators to simulate the radiation environment of space. The ASSERT program seeks to change that by creating compact, laboratory-based alternatives. This will allow for more frequent and affordable testing, accelerating the advancement of more resilient electronics.

The goal isn’t simply to replicate the effects of radiation, but to provide a secure environment for testing sensitive designs. This is crucial for national security applications where protecting intellectual property is paramount. Northrop Grumman’s recent presentation addresses both of these needs.

Northrop Grumman’s secure Testing Environment

Northrop Grumman’s demonstrated environment provides a secure and contained space for exposing microelectronics to radiation. While specific details about the technology are understandably limited due to security concerns, the company has stated that it represents a significant advancement in compact radiation testing capabilities. It allows engineers to assess the vulnerability of chips to SEEs without the logistical challenges and security risks associated with traditional heavy-ion facilities.

“This demonstration is a key milestone in our work with DARPA to revolutionize radiation testing,” said a Northrop Grumman spokesperson. “By providing a secure, in-house capability, we can accelerate the development and deployment of more reliable and resilient electronics for critical missions.”

Key Features of the New Environment:

• Compact Design: Reduces the footprint and cost compared to traditional facilities.
• Enhanced Security: protects sensitive intellectual property during testing.
• Realistic Radiation Simulation: Accurately replicates the radiation environment of space.
• Rapid Testing: Enables faster turnaround times for design validation.

Why this Matters for Space Exploration and National Security

The implications of this advancement are far-reaching. More reliable electronics are essential for:

• Space Exploration: Ensuring the longevity and functionality of satellites, probes, and future space habitats.
• National Security: Protecting critical infrastructure and defense systems from disruption.
• commercial Satellites: Improving the reliability of dialog and broadcasting services.
• Avionics: Enhancing the safety and performance of aircraft.

as space becomes increasingly congested and contested, the need for radiation-hardened electronics will onyl grow. This technology will play a vital role in maintaining a technological edge and ensuring the success of future missions.

Looking Ahead

Northrop Grumman plans to continue refining and expanding its secure radiation testing capabilities under the ASSERT program. Future developments may include the integration of advanced data analytics and machine learning to predict and mitigate SEE vulnerabilities. The company is also exploring ways to make this technology more accessible to a wider range of users,including smaller businesses and research institutions.

The successful demonstration of this secure testing environment marks a significant step towards a more resilient and secure future for microelectronics in challenging environments. It highlights the importance of continued investment in research and development to address the evolving threats posed by radiation.
