1.6 cell S-band
Copper cathode
Repetition rate: 10Hz

The beam exits the gun at 5 MeV.


Echo-7 is a proof-of-principle echo-enabled harmonic generation (EEHG) experiment which is being performed at the NLCTA at SLAC.  The experiment aims to test the physics of the EEHG concept and demonstrate scaling.  The 3rd, 4th, 5th, 7th, and possibly 15th harmonic of a 1590nm seed laser will be generated through the EEHG scheme.  In contrast to other schemes for generating harmonic bunching (e.g. HGHG), higher harmonics can potentially be reached with EEHG; in fact, due to the remarkable up-conversion efficiency, soft x-rays may be reached directly from a UV seed laser.
