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)

The Department of Energy, through Triad - DOE Contractor, is announcing a technology licensing opportunity for the M-Resistor under solicitation number S-167698. This special notice is classified under NAICS 335931 Current-Carrying Wiring Device Manufacturing and PSC 5961 Semiconductor Devices and Associated Hardware. There is no set-aside for this opportunity (NONE; explanation: NONE). Developed by Los Alamos National Laboratory, the M-Resistor is a pulsed power technology designed to protect high-voltage systems by managing reflected energy through an adjustable spark-gap path to an isolated ground.
The M-Resistor functions as a charge resistor for MARX generators, utilizing a clear epoxy housing and a dense plastic case to allow for direct visual inspection of internal components and spark switch positions. This design addresses limitations in previous X-ray charge resistor architectures by providing a controlled path for unwanted pulses, preventing damaging energy from returning to the power supply or traveling through the coaxial cable ground conductor. The technology currently carries a Technology Readiness Level of 4 with a US patent pending. Market applications include pulsed power research platforms, defense evaluation platforms, industrial electronics, and scientific research infrastructure.
The place of performance for this opportunity is Los Alamos, New Mexico. Responses are due by the deadline of December 9, 2026. Satya Srinivasan is the designated point of contact. This notice is intended to move inventions developed by researchers into commercial innovations through exclusive and non-exclusive licensing agreements and is not a call for external development services.
