Rotating X-ray beams!

During a very fun and interesting collaboration with Dr. Lars Loetgoring from the Advanced Research Center for Nanolithography and Vrije Universiteit in Amsterdam, we helped suggest some new ways to create and characterize X-ray beams that rotate as they propagate. While optical helical beams have been created for quite some time, this is the first time that they have been demonstrated in the X-ray regime. Please check out the paper here!
