| Keywords: NIST Puts a New Twist on the Electron Beam (5940496945).jpg NIST researchers twisted the flat electron wavefronts into a fan of helices using a very thin film with a 5-micron-diameter pattern of nanoscale slits which combines the wavefronts to create spiral forms similar to a pasta maker extruding rotini This method produces several electron beams fanning out in different directions with each beam made of electrons that orbit around the direction of the beam Credit B McMorran/NIST Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/5940496945/ NIST Puts a New Twist on the Electron Beam 2011-01-13 15 29 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/5940496945 2016-09-07 02 34 32 United States Government Work Uncategorized 2016 December 20 | ||||
