E164 & E164X: Experiment
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!
