title: An inverse free electron laser driven linear collider electron-positron B-factory

format: conference procceeding

conference: 1993 Particle Accelerator Conference

year: 1993

3 authors: N. Barov | C. Pellegrini | Sandweiss, J.

abstract: We discuss an electron-positron linear collider B-Factory using Inverse Free Electron Lasers (IFEL) to accelerate the beams. The requirements on luminosity, larger than 10/sup 33/ cm/sup -2/ s/sup -1/, and energy spread of a B Factory introduce stringent conditions on the accelerator and the interaction region. We study the longitudinal dynamics through the IFEL, the efficiency of the acceleration process, and the ratio of particles which become accelerated, and fall within the resonance. The device is found to perform well in the presence of large variations in the laser field intensity over the beam. We also discuss the laser system powering the IFEL, and some of the system tolerances. (7 References).

title: Use of an inverse free electron laser in a linear collider B factory

format: conference procceeding

conference: 3rd Advanced Accelerator Concepts Workshop

year: 1993

3 authors: C. Pellegrini | Sandweiss, J. | N. Barov

abstract: The authors examine the possibility of using an IFEL as an accelerator in a linear collider B Factory. An IFEL is able to utilize a sizeable fraction of the energy of the laser pulse used to accelerate the beams. It is also able to meet the stringent requirements imposed on the energy spread and luminosity at the interaction point. Two separate examples are considered, differing in the way the laser pulse energy is coupled to the electron beam. The first maximizes the slippage between the beam bunch and the radiation, in order to decrease the peak laser power. In the second example the slippage is minimized. This results in uniform beam loading and may in principle be run at higher efficiency and lower average power. The authors also address the laser required to drive this accelerator. The power and frequency requirements suggest the use of a FEL drive laser. The design for this system includes the use of superconducting cavities to accelerate the drive beam, which is then propagated through an initially constant period undulator that is tapered after saturation.
