The 1,000th magnet for the Advanced Photon Source Upgrade has arrived at Argonne. 

The APS Upgrade will replace the current electron storage ring with a state-of-the-art model that will be made up of 1,321 powerful magnets. These magnets will maintain the electrons in a circular orbit (allowing them to be “stored”), while keeping the size of the electron bunches as small as possible. This will allow the upgraded APS to generate X-ray beams 500 times brighter than the current facility, to enable new discoveries in a variety of fields.

The 1,000th magnet is an eight-pole fast corrector magnet, which is used to alter the trajectory of the electron beam as it circulates around the storage ring at nearly the speed of light. This magnet can steer the beam vertically and horizontally, and can control the size of the electron beam as well.
