[uhn-juh-layt-er, uhn-dyuh-] / ˈʌn dʒəˌleɪt ər, ˈʌn djə- /

noun

• undulators
  plural

1. Physics. an arrangement of magnets of alternating polarity inserted into the path of an electron beam, so that the alternating magnetic field causes the beam to oscillate or undulate, emitting intense electromagnetic radiation. Undulators are usually part of a synchrotron storage ring and are used to generate brilliant light.
