Superconducting RF Injector for High-Power Free Electron Lasers

PDF Version Also Available for Download.

Description

A key technology issue on the path to high-power FEL operation is the demonstration of reliable, high-brightness, photo-cathode injector operation. The physics and engineering conceptual design of a high-current superconducting RF injector has been completed and will be presented. The system, which is an outgrowth of the existing injector on the Jefferson Lab IRFEL[1], consists of an integrated room temperature DC photocathode gun and a 500 MHz superconducting RF accelerator. The device is compact and produces high-brightness beams. After DC acceleration in the gun, emittance compensation techniques are utilized to reduce the rms normalized emittance by over a factor of ... continued below

The system, which is an outgrowth of the existing injector on the Jefferson Lab IRFEL[1], consists of an integrated room temperature DC photocathode gun and a 500 MHz superconducting RF accelerator. The device is compact and produces high-brightness beams. After DC acceleration in the gun, emittance compensation techniques are utilized to reduce the rms normalized emittance by over a factor of two to {approximately}2-1/4 mm-mrad at the output of the RF accelerator. The design is based upon the existing geometry of the Jefferson Lab DC gun and will be capable of operation at 100 mA average beam current.
