Scientists have developed a new superconducting X-ray detector that's up to 1,000 times more sensitive than previous detectors. This breakthrough tool will help researchers study the properties of tiny materials and nanostructures.

Researchers at BESSY II have introduced a powerful new tool for studying X-rays. The instrument is called a Transition Edge Sensor (TES) spectrometer, and it's the first one in Europe to operate at a synchrotron facility. This device can detect photons emitted by samples much more efficiently than previous detectors. In fact, it's up to 100 to 1,000 times better at detecting these photons.

The TES spectrometer will help scientists study the electronic properties of atomically thin materials, nanostructures, and highly diluted atomic and molecular samples. This could lead to new insights into molecular chemistry or biology, as well as the quantum properties of systems in reduced dimensions.

The instrument consists of 248 superconducting sensors that become superconducting when cooled to a very low temperature. When X-rays interact with a sample, the sample emits photons that strike these sensors, causing them to briefly warm up and change their electrical resistance. This change is then measured using circuitry based on Superconducting Quantum Interference Devices (SQUIDs).

The TES spectrometer is connected to an ultra-high vacuum sample chamber that supports sample transfer, preparation, and measurement. The chamber also provides precise temperature control ranging from 10 K to room temperature.

This new tool is expected to revolutionize the field of X-ray spectroscopy. It will enable researchers to study materials that were previously difficult or impossible to analyze. For example, the spectrometer can dramatically reduce data collection times, allowing scientists to complete experiments in just minutes that would normally take hours.
