What is a wiggler?
A wiggler is a type of insertion device. It consists of an array of magnets which cause the electron beam to follow a “wiggling” path. This causes the light to be produced in a wide cone, spanning a broad spectrum of X-rays. Wigglers are used in beamlines where the priority is for very high energy X-rays – for example the Extreme Conditions beamline, which has a superconducting wiggler. Here, high energy X-rays up to 100 keV are required to penetrate into a diamond anvil cell.
