Klystron Repairs

The Department of Energy's Oak Ridge National Laboratory is seeking klystron repair services for SNS 805MHz, 5MW Peak Power Pulsed Klystrons used in the Spallation Neutron Source particle accelerator's Coupled Cavity Linac section. The solicitation requires comprehensive repair capabilities for these high-power RF devices that operate at 805.0 MHz with peak output power of 5.0 MW, minimum RF duty factor of 9%, and pulse repetition rate of 60 Hz. Contractors must demonstrate technical expertise in klystron technology, provide factory testing within 14 months of order receipt, conduct multiple design reviews, and submit detailed documentation including test reports and maintenance procedures. The procurement will be evaluated using the Lowest Price Technically Acceptable (LPTA) method with proposals due on August 25, 2025. Offerors must submit comprehensive proposal packages including technical proposals detailing personnel qualifications and repair methodologies, cost proposals with detailed breakdowns, and various compliance certifications.

This procurement is not designated as a set-aside opportunity and is open to full and open competition under NAICS code 334515 for Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals. No current incumbents or contractors are identified in the solicitation documents, though the detailed technical specifications suggest this is specialized work requiring extensive expertise in high-power klystron technology. The contract structure anticipates a firm fixed-price arrangement with payment terms of Net 30 days via electronic funds transfer, though specific award values are not disclosed in the available documentation. The klystrons must meet stringent technical requirements including beam voltage less than 135 kV, maximum beam current of 72 amperes, minimum RF power gain of 50 dB, and 100,000-hour design lifetime with comprehensive warranty provisions. All work will be performed at Oak Ridge National Laboratory in Oak Ridge, Tennessee, with the selected contractor required to provide 80 hours of on-site support during acceptance testing and maintain detailed quality assurance programs throughout the repair process.
