What TAU Systems does
TAU's product portfolio centers on compact laser-plasma accelerators (60–100 MeV electrons at 100 Hz), the TAU eSEE radiation testing platform for space-bound electronics with independently tunable Linear Energy Transfer (LET) and sub-micron beam control, and X-ray free-electron laser (XFEL) systems intended for next-generation semiconductor lithography. The company operates TAU Labs, a 22,300 sq ft privately owned application center in Carlsbad, California, which functions as the world's first commercial laser-particle accelerator facility. TAU generates revenue through two primary channels: (1) direct sales of complete laser-driven accelerator and XFEL systems priced at $10 million and above, and (2) Beamtime-as-a-Service at TAU Labs, a usage-based offering for radiation testing, X-ray imaging, and metrology applications. Target customers span semiconductor manufacturers (advanced lithography and chip imaging), satellite and spacecraft developers (single event effects radiation testing), defense agencies (DARPA ASSERT programme), pharmaceutical and biotech firms (protein and viral imaging), and battery and energy materials researchers. As of 2026, the company has one disclosed commercial customer (a major satellite manufacturer), is collaborating with NASA JPL, Berkeley Lab, CERN's RADNEXT 2030 network, Thales (laser systems supplier), and DARPA, and has raised $35 million across two seed rounds led by Quantonation and Team Global.

TAU Systems product offering
Product offeringCore offering
TAU Systems develops and sells compact laser-powered particle accelerators and X-ray free-electron laser (XFEL) systems based on proprietary laser wakefield acceleration (LWFA) technology, shrinking conventional kilometer-scale accelerators to room-sized systems. The company sells complete accelerator and XFEL systems to enterprise customers and operates TAU Labs in Carlsbad, California, offering Beamtime-as-a-Service for radiation testing of space electronics, semiconductor imaging, metrology, and research applications.
Product overview
TAU Systems develops and commercializes compact laser-powered particle accelerators and X-ray free-electron lasers that shrink conventional accelerator technology from kilometers to meters. The product portfolio centers on two core hardware offerings: compact laser-plasma accelerators (using laser wakefield acceleration technology) and X-ray free-electron lasers (XFEL) for lithography. These are complemented by the TAU eSEE radiation testing system for space electronics, and delivered through TAU Labs facility (beamtime-as-a-service model) in Carlsbad, California. Systems are available for purchase or accessed through service center arrangements.
