Upper limit for the accelerating gradient in the collinear wakefield accelerator as a function of the transformer ratio by S. S. Baturin, A. Zholents

“…The interrelation between the accelerating gradient and the transformer ratio in the collinear wakefield accelerator has been analyzed. It has been shown that the high transformer ratio and the high efficiency of the energy transfer from the drive bunch to the witness bunch can only be achieved at the expense of the accelerating gradient. …”

Scaling of the longitudinal electric field and transformer ratio in a nonlinear plasma wakefield accelerator by I. Blumenfeld, C. E. Clayton, F. J. Decker, M. J. Hogan, C. Huang, R. Ischebeck, R. H.

“…The scaling of the two important figures of merit, the transformer ratio T and the longitudinal electric field E_{z}, with the peak drive-bunch current I_{p}, in a nonlinear plasma wakefield accelerator is presented for the first time. The longitudinal field scales as I_{P}^{0.623±0.007}, in good agreement with nonlinear wakefield theory (∼I_{P}^{0.5}), while the unloaded transformer ratio is shown to be greater than unity and scales weakly with the bunch current. …”

Positron transport and acceleration in beam-driven plasma wakefield accelerators using plasma columns by S. Diederichs, T. J. Mehrling, C. Benedetti, C. B. Schroeder, A. Knetsch, E. Esarey, J. Osterhoff

“…A finite radius plasma is proposed to generate wakefields that can focus and accelerate positron beams in a plasma wakefield accelerator. The finite radius plasma reduces the restoring force acting on the plasma electrons forming the plasma wakefield, resulting in an elongation of the on-axis return point of the electrons and, hence, creating a long, high-density electron filament. …”
