Strain-Compensated AlInGaAs-GaAsP Superlattices for Highly-Polarized Electron Emission
A. V. Subashiev, L. G. Gerchikov, Yu. A. Mamaev +5
Spin-polarized electron emission from the first superlattice photocathodes developed with strain compensation is investigated. An opposite strain in the quantum well and barrier la…
A systematic study of polarized electron emission from strained GaAs/GaAsP superlattice photocathodes
T. Maruyama, D. -A. Luh, A. Brachmann +8
Spin-polarized electron photoemission has been studied for GaAs/GaAsP strained superlattice cathodes grown by gas-source molecular beam epitaxy. The superlattice struct…
Recent Progress at SLAC Extracting High Charge from Highly-Polarized Photocathodes for Future-Collider Applications
J. E. Clendenin, A. Brachmann, E. L. Garwin +8
Future colliders such as NLC and JLC will require a highly-polarized macropulse with charge that is more than an order of magnitude beyond that which could be produced for the SLC.…
The SLAC Polarized Electron Source
J. E. Clendenin, A. Brachmann, T. Galetto +4
The SLAC PES, developed in the early 1990s for the SLC, has been in continuous use since 1992, during which time it has undergone numerous upgrades. The upgrades include improved c…
