Enhancement of Photoemission on P-type GaAs using Surface Acoustic Waves
Boqun Dong, Andrei Afanasev, Rolland P. Johnson +1
We demonstrate that photoemission properties of GaAs photocathodes (PCs) can be altered by surface acoustic waves (SAWs) generated on the PC surface due to dynamical piezoelectric…
Resonant interaction of the electron beam with a synchronous wave in controlled magnetrons for high-current superconducting accelerators
G. Kazakevich, R. Johnson, V. Lebedev +2
A simplified analytical model of the resonant interaction of the beam of Larmor electrons drifting in the crossed constant fields of a magnetron with a synchronous wave providing a…
Phase Grouping of Larmor Electrons By a Synchronous Wave In Controlled Magnetrons
G. Kazakevich, R. Johnson, V. Lebedev +1
A simplified analytical model based on the charge drift approximation has been developed. It considers the resonant interaction of the synchronous wave with the flow of Larmor elec…
Phase and Power Control in the RF Magnetron Power Stations of Superconducting Accelerators
G. Kazakevich, R. Johnson, V. Lebedev +2
Phase and power control methods that satisfy the requirements of superconducting accelerators to magnetron RF sources were considered by a simplified kinetic model of a magnetron d…
Storage-ring Electron Cooler for Relativistic Ion Beams
F. Lin, Y. S. Derbenev, D. Douglas +5
Application of electron cooling at ion energies above a few GeV has been limited due to reduction of electron cooling efficiency with energy and difficulty in producing and acceler…
High-power magnetron transmitter as an RF source for superconducting linear accelerators
Grigory Kazakevich, Rolland Johnson, Gene Flanagan +10
A concept of a high-power magnetron transmitter for operation within a wideband control feedback loop in phase and amplitude is presented. This transmitter is proposed to drive Sup…
