Neutrons

oakridgelabnews posted a photo: Spallation Neutron Source RF Circulators. The RF circulators (three round disks in the middle) are positioned throughout the SNS Klystron Gallery. They protect the klystrons by directing the RF energy out of the klystrons down to the LINAC tunnel. Any reflected energy that comes back up toward the klystron gets directed to an RF load instead of the klystron. If the energy would happen to make it back to the klystron, it could cause damage. Because of the electroma
