Advanced Event-Mode Neutron Imaging System with a Large Area Detector.

Oak Ridge National Laboratory (ORNL), operating under the Department of Energy, is seeking proposals for an Advanced Event-Mode Neutron Imaging System with a Large Area Detector through Request for Proposal PR422299. The system requires sophisticated optical detection capabilities utilizing four Timepix-3 chips with a 512x512 pixel matrix, achieving 1.56 nanosecond time resolution and 300 million hits per second count rate, along with a 300-millimeter silicon sensor providing over 90 percent quantum efficiency. Additional requirements include a large area image intensifier optimized for neutron imaging, 10 Gigabit per second ethernet data transfer capabilities, remote control functionality, and comprehensive software supporting noise-free neutron detection with subpixel resolution. The solicitation will be awarded on a Lowest Price Technically Acceptable (LPTA) basis, meaning proposals will be evaluated first for technical acceptability and then price will be the determining factor. Proposals are due by 5 p.m. EST on December 18, 2025, with questions from prospective offerors accepted until December 13, 2025.

This is a competitive, fixed-price procurement with no set-aside designation, and no incumbent contractor information has been identified. The specific award value or budget range has not been disclosed in the solicitation materials. The contract scope includes a 12-month warranty, initial commissioning with installation and site-acceptance testing, on-site support for system integration, and delivery in a protective pelicase box for transportation. Offerors must demonstrate the ability to provide software binaries compatible with Ubuntu 20.04 and 22.04, support dual Time-to-Digital Converter functionality for external event synchronization, and enable Serval architecture control via HTTP REST protocol. The place of performance is Oak Ridge, Tennessee 37830, and prospective offerors must be registered in the System for Award Management (SAM) and comply with all representations and certifications requirements, including Activity Hazard Analysis submittal prior to beginning any physical on-site work.
