M-Resistor, developed by Los Alamos National Laboratory, offers pulsed power operators a more protective and more inspectable way to manage reflected energy in high-voltage systems. Unlike prior resistor designs that could fail internally without obvious signs and could return damaging energy to the power supply, M-Resistor adds an adjustable spark-gap path to isolated ground, improving protection across different vo...
View moreTechnical Description
M-Resistor is an improved resistor assembly derived from an earlier X-ray charge resistor architecture, but modified to address inspection, grounding and reflected-energy protection limitations identified in prior use. The M-Resistor design replaces a steel enclosure with a dense plastic case and uses clear epoxy potting so internal components remain visible for inspection. A central feature is the inclusion of an adjustable spark switch, or spark air gap, that can be set by a worker according to the voltage used to energize the system. That adjustability adds operating flexibility, missing from prior products.
M-Resistor is intended for MARX-generated pulsed power technology and is designed to route reflected electrical pulses to a secondary isolated ground rather than back to the power supply or through the coaxial cable ground conductor.
Advantages
• Helps protect power supplies from damaging reflected energy
• Adds an adjustable response for different operating voltages
• Improves worker visibility during setup and inspection
• Makes internal damage easier to detect because of clear epoxy potting
• Uses an isolated ground path to improve system safety
• Fits pulsed power environments that need a practical fail-safe layer
Market Applications
• Pulsed Power Systems (research platforms, test systems, laboratory pulse generation)
• Instrumentation (charging systems, protective interfaces, power conditioning assemblies)
• Defense (pulsed X-ray systems, evaluation platforms, hardened test assets)
• Industrial Electronics (specialty power equipment, high-voltage integration packages, reliability upgrades)
• Scientific Research Infrastructure (physics laboratories, experimental facilities, university-scale pulsed power setups)

This special notice, identified as solicitation number S-167698, details a technology licensing opportunity for the M-Resistor, a high-voltage system component developed by Los Alamos National Laboratory. Managed by TRIAD - DOE Contractor for the Department of Energy, this technology serves as a charge resistor for MARX-generated pulsed power systems while providing a controlled path for reflected energy. The design features a clear epoxy housing and dense plastic case, replacing traditional steel enclosures to allow for visual inspection of internal components. It incorporates an adjustable spark-gap path to an isolated ground, which protects power supplies by diverting reflected pulses based on specific voltage settings.
The M-Resistor is currently at Technology Readiness Level 4 with a U.S. patent pending. This technology is classified under NAICS code 335931, Current-Carrying Wiring Device Manufacturing, and PSC 5961, Semiconductor Devices and Associated Hardware. Its primary applications include pulsed power research platforms, instrumentation charging systems, defense-related X-ray systems, and high-voltage industrial electronics. The design aims to increase equipment longevity and system safety by providing a fail-safe layer that is more inspectable and adaptable than prior resistor architectures.
The response deadline for this licensing opportunity is December 9, 2026. Satya Srinivasan serves as the point of contact for the notice, which was published on June 8, 2026. The place of performance is Los Alamos, New Mexico. There are no set-asides associated with this notice, and the government is seeking existing or start-up companies interested in exclusive or non-exclusive licensing agreements to commercialize the invention.
