A team of researchers from DESY, the University of Hamburg and the Technical University of Dortmund has managed to demonstrate seeding by a procedure known as HGHG at the sFLASH test facility in April. "Seeding" is supposed to make the generation of radiation in a free-electron laser more reproducible by enclosing a laser pulse in the magnetic undulator together with the packets of electrons that emit the light. By demonstrating seeding, the scientists have reached an important milestone on the way to developing a procedure for incorporating seeding in user experiments conducted at FLASH.
