Breaking the supposed accuracy limit for TES detectors

Scientists at SRON Netherlands Institute for Space Research are developing a detection technique (TES) that measures the energy of individual photons, for example in X-rays from the distant universe. Until now, it was assumed that the wiring on the detector chip brings along an inherent whimsicality in accuracy. The research team has now discovered that there is room for improvement after all. They have published their report in Physical Review Applied.
