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 کاملFeshbach–Fano R-matrix Method: Application to Potential Scattering
The general Feshbach-Fano R-matrix (FFR) procedure proposed recently by Nestmann [J. Phys. B 31, 3929 (1998)] makes it possible to construct resonance metastable states of transient molecular ions and their coupling elements to the background scattering continuum. These quantities are needed for the study of nuclear dynamics in the framework of the nonlocal resonance model. The performance of t...
متن کاملTion of Polarized Electron Multiple Scattering Asymmetries
The first order polarization dependent electron multiple scattering theory of Toptygin has been evaluated for realistic experimental conditions. The result is a prediction of essentially no beam depolarization. Recent experiments are discussed, and calculations are made to illustrate the influence of multiple scattering on Mott double scattering asymmetries. (Submitted to Phys. Rev.) * Supporte...
متن کاملElectron Scattering with Polarized Targets at TESLA
Measurements of polarized electron-nucleon scattering can be realized at the TESLA linear collider facility with projected luminosities that are about two orders of magnitude higher than those expected of other experiments at comparable energies. Longitudinally polarized electrons, accelerated as a small fraction of the total current in the e+ arm of TESLA, can be directed onto a solid state ta...
