Abstract
An x-ray spectrometer includes: an x-ray plasma source that produces first x-rays; an x-ray optic in optical communication with the x-ray plasma source and that: receives the first x-rays from the x-ray plasma source; focuses the first x-rays to produce second x-rays; and communicates the second x-rays to a sample that produces product x-rays in response to receipt of the second x-rays and second light; and a microcalorimeter array detector in optical communication with the sample and that receives the product x-rays from the sample.
Patent Description
Presently, there are no commercial tools for x-ray absorption and emission spectroscopy with picosecond time resolution. Additionally, there are no table-top tools for x-ray emission spectroscopy with picosecond time resolution. Previously, x-ray emission spectroscopy with this level of time resolution was only performed at two large x-ray free electron laser facilities (one in the U.S., and one in Japan). This invention changes all of that.
Features
- Our apparatus performs absorption and emission spectroscopy with few-ps time resolution.
- At synchrotrons (~$500M or more), emission spectroscopy has only been performed with 100 ps resolution (ours is smaller, faster (science faster), cheaper, and can perform absorption spectroscopy).
- At x-ray free electron lasers (~$500M or more), emission spectroscopy can be performed with better time resolution than ours. There are 3 in the world right now (ours is smaller, faster (science faster), cheaper, and can perform emission spectroscopy).
- There are no previous tabletop tools for ultrafast emission spectroscopy. (ours is faster (science faster), cheaper, and can perform absorption spectroscopy).
- Synchrotrons and x-ray free electron lasers can perform absorption spectroscopy with better time resolution than ours. There are ~10 sites worldwide with this capability. (ours is smaller, cheaper, and can perform emission spectroscopy).
- There have been tabletop demonstrations of absorption spectroscopy with comparable time resolution. Their data quality is usually worse than ours. (ours is more accurate and can perform emission spectroscopy).
