X-band Test AREA

The X-Band Test Area (XTA) is a test facilty dedicated to demonstrating the high peformances of X-Band based photoinjectors. ​There is a very strong demand for high brightness electron sources to drive Free Electron Lasers (FELs), Ultra-fast Electron Diffraction (UED), and Inverse Compton Scattering (ICS) facilities. 

The X-band technology was initially developed for the Next Linear Collider (NLC) until the superconductive technology was adopted when the NLC project evolved into the International Linear Collider (ILC).  X-Band is now extensively used for RF harmonic linearizer on S-Band based FELs. It is also the techonology adopted for CLIC, a possible alternative to NLC at CERN.  X-Band is proving its unique capabilities in the race to short time resolution with transverse deflectors. Also, very recently it was the technology at the basis of the first RF undulators tested in August 2012.  

Our first generation photoinjector was installed in the spring and summer of 2012. Commissioining started in August 2012 after first beam was generated on July 30th. 

Our facility is entirely devoted to R&D. Its experimental set-up is thus prone to generate innovation.  However, it also takes advantage of the many SLAC departments trained to provide support to user facilities, which insures reliability and efficacy in the operation.
