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.…
Surface Analysis of OFE-Copper X-Band Accelerating Structures and Possible Correlation to RF Breakdown Events
S. E. Harvey, F. Le Pimpec, R. E. Kirby +3
X-band accelerator structures meeting the Next Linear Collider (NLC) design requirements have been found to suffer vacuum surface damage caused by radio frequency (RF) breakdown, w…
Autopsy on an RF-Processed X-band Travelling Wave Structure
F. Le Pimpec, S. Harvey, R. E. Kirby +1
In an effort to locate the cause(s) of high electric-field breakdown in x-band accelerating structures, we have cleanly-autopsied (no debris added by post-operation structure disas…
