X-Ray Breakthrough: Superconducting Sensors Revolutionize Research
24 Jun
Summary
- New X-ray tool boosts photon detection efficiency by 100 to 1000 times.
- Enables study of atomically thin materials and diluted samples.
- Operates using 248 superconducting sensors near absolute zero.
A highly advanced X-ray research instrument has been commissioned at BESSY II, marking Europe's first synchrotron facility equipped with a superconducting Transition Edge Sensor (TES) spectrometer. This novel system achieves a 100 to 1000-fold increase in photon detection efficiency compared to traditional spectrometers. Developed collaboratively by HZB, MPI-CEC, and NIST, the instrument is set to transform the study of electronic properties in atomic monolayers, nanostructures, and diluted molecular samples.
The enhanced sensitivity of the TES array, comprising 248 superconducting sensors cooled to 25 milli-Kelvin, enables researchers to investigate quantum materials and systems in reduced dimensions. This advancement complements existing techniques and promises new insights into molecular chemistry and biology. Data collection times are also dramatically reduced, with experiments that previously took hours now completable in minutes. The system is installed at the BESSY II UE52-SGM beamline and includes advanced vacuum chamber capabilities, with future upgrades planned for magnetic field studies.
