Statement of Work and Specifications for an Electropolishing System
This Statement of Work specifies the technical requirements for an electropolishing system intended for specimen preparation in electron microscopy applications. The system must feature dual jets to direct electrolyte flow onto both sides of specimens simultaneously, achieving electron transparency within minutes without introducing artifacts. All polishing cell components must be constructed from electrolyte-resistant materials to withstand exposure to harsh acids and solvents. The system shall incorporate an integrated fiber optic light source and photodetector for automated monitoring, with adjustable photodetector sensitivity to enable precise control over final hole size. Additional thermal capabilities must include cryogenic functionality with temperature control down to -60°C.
The power controller shall precisely manage electrolyte flow, polishing voltage and current, light source intensity, and photodetector shutoff circuitry with integrated visual and audible alarm capabilities. The system must support both automatic and continuous pump and polishing operational modes. The Statement of Work was prepared by Michael J. Kulis, Analytical Science Group Lead within the Research and Engineering Directorate, dated April 3, 2026.

Statement of Work and Specifications for an electropolishing system.
All components in the polishing cell shall be made from electrolyte-resistant materials to ensure durability when using harsh acids or solvents.
The system shall use two jets to direct electrolyte flow onto both sides of a specimen at once, achieving electron transparency within minutes without inducing artifacts.
The system shall have an integrated fiber optic light source and photo detector to monitor the specimen, so that the system automatically stops the polishing process once perforation occurs.
Photodetector’s sensitivity shall be adjustable to allow precise control over the final hole size in the specimen.
The system shall have cryogenic capability, temperatures down to -60C.
The power controller shall precisely control the electrolyte flow.
The polishing voltage and current, light source, and photodetector shutoff circuit, and shall have both visual and audible alarms.
The system shall have auto and continuous pump an polishing modes.
