The Slac Polarized Electron Source*
The SLAC polarized electron source employs a photocathode DC high voltage gun with a loadlock and a YAG pumped Ti:sapphire laser system for colliding beam experiments or a flash lamp pumped Ti:sapphire laser for fixed target experiments. It uses a thin, strained GaAs(100) photocathode, and is capable of producing a pulsed beam with a polarization of ≥80% and a peak current exceeding 10 A. Its o...
متن کاملThe Slc Polarized Electron Source
A polarized electron source consisting of a 3-electrode photocathode gun and a flashlamp-pumped dye laser has been designed and built for the SLC and is currently undergoing commissioning. The source is described, and the operating configuration is discussed. The present status of the source and future plans are briefly indicated.
متن کاملPolarized Electron Source Development in Japan
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 کاملElectron spin polarization induced by linearly polarized light in a (110) GaAs quantum-well waveguide.
We report an experimental demonstration of generating electron spin polarization with linearly polarized light in a (110) GaAs quantum well. A detailed frequency-domain pump-probe study shows that the dynamic nuclear spin polarization arising from the oriented electron spins results in a strong dependence of the electron spin splitting on the photon energy and intensity of the linearly polarize...
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...
