Transforming Quantum Measurement into Practical Technology
Innovative Solutions R&D LLC develops coherent measurement technologies that enable observations beyond the capabilities of conventional instrumentation.
Mission
Research-driven innovation
Innovative Solutions R&D LLC develops transformative sensing and measurement technologies by translating discoveries in fundamental physics into practical scientific and engineering solutions.
Our work combines quantum sensing, accelerator science, microwave engineering, optics and advanced signal processing to enable measurements previously beyond the reach of conventional instrumentation.
Technology platforms
One measurement philosophy, multiple applications
Precision Spin Metrology
High-sensitivity techniques for monitoring spin dynamics and polarization in storage rings and precision experiments.

Why ISRD?
We build technologies that measure what today's instruments cannot.
Traditional detectors often discard phase and coherence information. ISRD develops coherent approaches designed to recover that information and extend the reach of scientific observation across fundamental physics, medicine, aerospace, critical infrastructure and advanced sensing.

Muon g−2 instrumentation
At Brookhaven E821, Yannis Semertzidis led the design of the electrostatic quadrupole focusing system and proposed, designed and built the pulsed magnetic kicker system. For Fermilab E989, the IBS-CAPP team designed, built and implemented an RF beam-manipulation system that reduced coherent betatron oscillations by about an order of magnitude and stored-muon losses by about a factor of five.
The 2026 Breakthrough Prize in Fundamental Physics recognized the Muon g−2 experimental program, including the CERN, Brookhaven and Fermilab collaborations. Yannis Semertzidis contributed to the Brookhaven and Fermilab collaborations.
Axion dark matter
Leadership in the development of high-sensitivity haloscopes, cryogenic microwave systems and new coherent electro-optic detection concepts.
Precision spin physics
Long-term development of electric-dipole-moment methods, storage-ring concepts and coherent polarimetry.
Our direction
Building the next generation of measurement technologies
ISRD is focused on converting coherent measurement concepts into practical systems for science, medicine, aerospace, critical infrastructure and sensing. The objective is not only to improve existing instruments, but to create new capabilities where conventional approaches reach their limits.
