Recent Developments on Strained Photocathode Research*
نویسندگان
چکیده
For the past five years, strained GaAs photocathodes have been used for the SLAC polarized electron source producing electron beams having a spin polarization of 78% (85%) for high (low) current operation. Photocathode research has been continuously conducted to understand the cathode characteristics and to improve performances. This paper describes the recent developments in the strained photocathode research at SLAC.

Polarization Possibilities of Small Spin-Orbit Interaction in Strained-Superlattice Photocathodes
Strained-superlattice photocathodes based on InGaP/GaAs were investigated. The photocathode performance is found highly dependent on the superlattice parameters. The electron confinement energy in superlattice appears important.
متن کاملThe Polarized Electron Source of the Stanford Linear Accelerator Center*
The Stanford Linear Accelerator has been running with polarized electrons both in the collider (SLC) mode and in the fixed target mode. The accelerator's polarized electron source is based on a thin, strained GaAs photocathode, which is held at a negative high voltage and illuminated by a Titanium Sapphire laser. The reliability of the source was better than 95% during the eight-month-long 1993...
متن کاملEffects of atomic hydrogen and deuterium exposure on high polarization GaAs photocathodes
1098-4402= Strained-layer GaAs and strained-superlattice GaAs photocathodes are used at Jefferson Laboratory to create high average current beams of highly spin-polarized electrons. High electron yield, or quantum efficiency (QE), is obtained only when the photocathode surface is atomically clean. For years, exposure to atomic hydrogen or deuterium has been the photocathode cleaning technique e...

We have continued the basic research to develop the photocathodes for the polarized electron source and to construct the guns for the high energy accelerator , such as e + e ? linear colliders. Four subjects, (1) photocathode development of strained layer superlattice, (2) photoluminescence study of spin relaxation inside the cathode, (3) study of eld emission dark current, and (4) gun design a...
متن کاملThe High Peak Current Polarized Electron Source of the Stanford Linear Collider*
The Stanford Linear Collider Injector requires two 2 ns pulses of 4.5-5.5 x 1010 electrons, separated by 61 ns at 120 hz, from its source. Since 1992, these currents have been provided by a polarized electron source based on GaAs photocathodes. A beam polarization of 76 + 4% has been measured at the end of the 50 GeV linac. At low photocathode quantum efficiencies, and for excitation near thres...
