Scientists find new way to measure important beam property – Phys.org

For a wide variety of high-powered scientific instruments, from free-electron lasers to wakefield accelerators to electron microscopes, generating a bright electron beam that has specific properties represents one of the most significant challenges. These instruments can be used for investigating the atomic level properties of matter or for accelerating particles to high energies.
Scientists seeking to create the best beams possible are interested in two particular qualities that determine how …
