2 Nov
Summary
- SLAC's LCLS-II uses ultrafast X-ray pulses to film molecular movies.
- It captures real-time chemical reactions and electron motion at high speed.
- Scientists achieve temperatures colder than outer space for experiments.
At SLAC National Accelerator Laboratory, the Linac Coherent Light Source II (LCLS-II) is revolutionizing scientific observation. This facility operates the world's most powerful X-ray laser, enabling scientists to capture molecular movies.
Ultrafast femtosecond pulses allow for the real-time filming of chemical reactions and the intricate motion of electrons. These capabilities are crucial for understanding fundamental processes at the atomic level.
To achieve its groundbreaking results, LCLS-II utilizes cryomodules, operating at temperatures colder than outer space. This extreme cooling is essential for generating the high-energy hard X-rays required for these advanced experiments.
The facility's applications extend to real-world problems, with ongoing experiments exploring future scientific frontiers. SLAC itself is a vast, two-mile particle accelerator situated near Stanford University.
