The scientists were able to image the material for the next generation of particle accelerators at atomic resolution. Cornell University reports.
Superconducting particle accelerators used to create X-ray-free electron lasers rely on niobium (Nb) superconducting RF cavities to generate high-energy beams. However, to maintain the superconducting state of niobium, the temperature must not exceed a few kelvins; a bulky, complex and expensive helium cooler system is used for this. To solve this problem, physicists are looking for superconducting materials that can operate at temperatures above 2 kelvins, with performance characteristics comparable to niobium resonators. One of the promising candidates for this role is triniobium stannide, a tin and niobium Nb compound.3sec. However, scientists do not know exactly how the films of this substance are formed.
Now scientists have succeeded to obtain Detailed image of tin on niobium oxide. The image has atomic resolution and was obtained using a scanning tunneling microscope, which allows you to obtain an image of the microrelief of the material. The authors hope that their observations will make it possible to create simpler X-ray lasers, necessary both for experiments in basic physics and for studying the molecular structure of substances and medical examinations.
