title: Status of RF photoinjector and PWT linac at UCLA
format: conference proceeding
conference: Linear Accelerator Conference 1992
year: 1992
12 authors: S. Park | N. Barov | S. Hartman | C. Pellegrini | J.B. Rosenzweig | P. Tran | G. Travish | R. Zhang | P. Davis | G. Hairapetian | C. Joshi | N. Luhmann
abstract: The authors report the present status of RF photoinjector and plane wave transformer (PWT) linac for the production of 20 MeV/c electron beam. The photoinjector is a 1/sup 1///sub 2/ cell pi -mode standing wave structure operating at 2.856 GHz with photoelectrons generated on a copper cathode by 4 ps long laser pulse at 206 nm. Measurements of the beam of photoelectrons are underway at various experimental parameters. The PWT has been tested at low power to investigate its mode structure. An overview of the system, latest data, and future directions are presented. (5 References).

title: Particle wakefield accelerators
format: conference proceeding
conference: Linear Accelerator Conference 1992
year: 1992
1 author: J.B. Rosenzweig
abstract: A wakefield accelerator is a device which employs large amplitude electric fields generated in the wake of an intense particle beam to accelerate other trailing charged particles to high energy. The environment which causes the beam to generate this wakefield can be any which supports the propagation of slow waves (v_phi < c), e.g. plasma, dielectric-lined wave-guide, or a standard disk-loaded linac structure. In addition, the acceleration beam axis may also be either collinear or parallel to the driving beam. The typical application considered for this type of linear accelerator is a future linear collider, and therefore particular attention is paid to such issues as accelerating gradient, power efficiency, and single and multiple bunch stability. In this analysis, a unified discussion of the principles behind wakefield acceleration will be presented, and constraints on power coupling, (which places limits on the accelerating gradient) and accelerating efficiency will be explored for both collinear and parallel wakefield accelerators. The effects of transverse impedances in these schemes will also be discussed, and the role of the possible beneficial effects introduced by implementation of deflection mode damping examined. Recent advances in theoretical and experimental development of wakefield accelerators will be presented, as well as prospects for future technology development and experiments at linear accelerator research facilities.
