Tecnar High-Speed Particle Tracking System

The National Aeronautics and Space Administration Shared Services Center has issued a Special Notice for a sole source procurement of a Tecnar High-Speed Particle Tracking System. NASA intends to award this contract to JP SAUER INC of Montgomery, Ohio, under FAR 13.106-1(b)(1)(i), having determined they are the sole provider of this specialized system. The procurement involves a Turnkey DPV Evolution system with specific technical requirements for particle diagnostic capabilities, to be delivered to NASA Langley Research Center. This acquisition falls under NAICS Code 541330 for Engineering Services and will utilize commercial items and services procedures under FAR Parts 12 and 13. The system is intended for measuring particle temperature, velocity, and size within plasma spray chambers under vacuum conditions.

The purpose of this Special Notice is to inform the contracting community of NASA's intent to proceed with a sole source acquisition while providing an opportunity for other qualified organizations to demonstrate their capabilities. Interested contractors must submit their capabilities and qualifications in writing to the primary point of contact, Shanna Patterson, no later than 7:00 a.m. Central Standard Time on August 4, 2025. The procurement is justified based on the unique capabilities of the Tecnar DPV Evolution system with CPS 2000 laser, which offers dual-speed configuration, 2% velocity accuracy, and the ability to measure particle temperatures up to 1050°C with 3% accuracy. NASA has determined that alternative particle measurement systems are inferior as they typically measure only single parameters, lack vacuum compatibility, or do not have equivalent scientific validation. The government retains sole discretion to determine whether to conduct this procurement on a competitive basis, with an estimated performance period of 8 weeks after receipt of order.
