Polarized Electrons for Linear Colliders
J. E. Clendenin, A. Brachmann, E. L. Garwin +7
Future electron-positron linear colliders require a highly polarized electron beam with a pulse structure that depends primarily on whether the acceleration utilizes warm or superc…
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…
Atomic Hydrogen Cleaning of Polarized GaAs Photocathodes
T. Maruyama, D. -A. Luh, A. Brachmann +6
Atomic hydrogen cleaning followed by heat cleaning at 450C was used to prepare negative-electron-affinity GaAs photocathodes. When hydrogen ions were eliminated, quantum ef…
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.…
