E164 & E164X: Experiment


These experiments all take place at the Stanford Linear Accelerator Center
(SLAC) in the Final Focus Test Beam (FFTB).

For the E164 & E164X experiments we are working to attain ultrahigh gradient plasma-wakefield acceleration.  Ultrahigh gradient, in this context, refers to peak acceleration gradients of >10 GeV/m.  These accelerating gradients are now possible due to the inclusion of a chicane installed along the linac as well as a dogleg at the beginning of the FFTB.  This chicane and dogleg combination allows us to compress the bunch length of the incoming electron beam from 600 microns (E157 & E162 parameters) down to 50-12 microns for the E164 experiments.  The accelerating gradient of the PWFA is inversely proportional to the square of the bunch length.  So a change in bunch from 600 microns to 12 microns should increase the accelerating gradient by 2500!

We believe that a successful demonstration of this experiment will be a truly
significant and defining accomplishment in the advanced accelerator research field.
