Professor Robert L. Byer from the Department of Applied Physics at Stanford University will be giving a lecture which will be available across all SUPA rooms.

Abstract
In November 2004 we successfully accelerated electrons with a visible modelocked laser source.  Today we are conducting experiments at SLAC to develop photonic bandgap dielectric based accelerator structures to efficiently couple laser radiation to electrons.  The dielectric structures allow laser accelerators to operate at accelerating gradients of 1GeV/meter.  We have explored the possibility of laser accelerator driven cohernt X-rays using a free electron laser.  The approach looks promising because of the replacement of the traditional magnet based undulator with a laser driven dielectric based undulator.  Progress toward the laser accelerator and coherent X-ray source will be discussed.
