ELYTT ENERGY designed a in vacuum undulator for CELLS, entity responsible for ALBA synchrotron construction and operation. ALBA is a synchrotron type particle accelerator to be used as synchrotron light source. The objective of such facility is to accelerate electron beams and maintain them in a circular trajectory with magnetic fields, so that x rays are generated tangentially to the electron beam trajectory. X rays are used in several experimental lines fixed around the storage ring, for different science investigation such us Biology, Chemics, Environmental Sciences, Material Science… Once the electron beam has been accelerated at the linear accelerator and the booster, the beam is directed to the storage ring. The storage ring forces the beam to a circular trajectory using magnetic fields. At the same time, beam energy is maintained with radiofrequency cavities. X rays are obtained through insertion devices and through dipoles. Dipoles change electron beam trajectory in some degrees. This way, the beam emits x ray tangentially to the trajectory. The undulator makes the electron beam to follow a undulating trajectory. This undulation makes the beam to emit x ray, obtaining a higher intensity light than dipoles. One of the main characteristics of the undulator designed by ELYTT ENERGY is that the magnetic structure is immersed in high vacuum. This aspect implies higher design difficulties, because selected materials and devices must be compatible with UHV (Ultra High Vacuum). Click here to enlarge specification table
