UPDATED ALS SHB pulsed RF HPA

The Department of Energy seeks two Sub-Harmonic Buncher pulsed Radio Frequency High Power Amplifiers (one at 125 MHz, one at 500 MHz) for the Advanced Light Source at Lawrence Berkeley National Laboratory, with proposals due November 18, 2026, and questions due October 23, 2026. The solicitation has been updated; the Statement of Work and Engineering Specification have been modified, and contractors must submit revised proposals reflecting those changes.

Place of performance is Berkeley, California. The procurement is open competition, no set-aside. NAICS code is 334220 (Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing), with a small business size standard of 1,250 employees. PSC code is 5996 (Amplifiers).

Each amplifier must deliver 25 kW flat-top RF output power in pulsed mode, employ latest solid-state LDMOS FET, GaN FET, or equivalent technology, achieve mean time between failures exceeding 150,000 hours for continuous 24/7 operation, and tolerate no more than four interruptions per year. The design must incorporate modular RF amplifier modules with fault tolerance (up to 10% module failure while maintaining 20 kW output), N+2 redundancy for DC power supplies, forced clean air cooling with variable-speed fans, and comprehensive monitoring via a 15-inch HMI touchscreen with EPICS IOC compatibility. Vendors must obtain NRTL certification to applicable US standards (NFPA 70, NFPA 70E, UL-508A, UL-61010-1, UL-60950-1) through desk review and preliminary and final field inspections, conduct NIR safety surveys, and obtain California-licensed structural engineer certification. Maximum cabinet dimensions are 1.16m wide by 0.76m deep by 2.37m high.

The contract is structured as firm fixed price with milestone-based payments dependent on successful completion of progressive stages through final Site Acceptance Testing. Maximum delivery is 18 months after receipt of order. The vendor must maintain an ISO-9001 compliant quality assurance program, establish configuration management controls, conduct bi-weekly progress meetings with LBNL, submit monthly progress reports, and provide on-site warranty commencing upon successful SAT. All design documentation and engineering work product become LBNL property. Proposals must address four evaluation factors: Ability to Meet Technical Requirements and Technical Approach; Delivery & Schedule; Quality Assurance; and Past Performance. Award will be made to the responsive and responsible offeror providing best overall value considering technical merit, schedule, quality, past performance, and cost.
