Positioning of Bunches in a Multibunch Wakefield Acceleration Scheme for Increasing the Beam Flight Range | |
|
||
| To increase the acceleration gradients and the energy transferred to the accelerated bunch in the wakefield accelerating structures, triangular profiling of the charge distribution in the driver bunch is used, as well as various (RBT and FBT) multi-bunch wakefield acceleration schemes. However, along with the coherent summation of the longitudinal fields used to accelerate the witness bunch, parasitic transverse fields are also increasing, which deflect the driver beam from the axis of the waveguide. It is proposed to use the difference in the frequencies of the accelerating and deflecting fields to significantly reduce the influence of the deflecting fields on the dynamics of the bunch by organizing a multi-bunch wake acceleration scheme with a special positioning of the bunches. Numerical simulation of the fields and beam dynamics in the proposed accelerating scheme is carried out. | ||
