The group is recognized for innovations transforming the readout of cryogenic sensors and producing best-in-the-world x-ray reference data. They created a unique system that improves the signal extraction rate from sensor arrays by 400-fold and pioneered measurement techniques that yield accurate absolute energy measurements with much higher precision over broader ranges than previously possible. These achievements accelerate the impact of x-ray metrology in materials analysis for industrial applications and in nuclear security and astrophysics.
