High Energy Polarized Electron Beams

PDF Version Also Available for Download.

Description

In nearly all high energy electron storage rings the effect of beam polarization by synchrotron radiation has been measured. The buildup time for polarization in storage rings is of the order of 10{sup 6} to 10{sup 7} revolutions; the spins must remain aligned over this time in order to avoid depolarization. Even extremely small spin deviations per revolution can add up and cause depolarization. The injection and acceleration of polarized electrons in linacs is much easier. Although some improvements are still necessary, reliable polarized electron sources with sufficiently high intensity and polarization are available. With the linac-type machines SLC at ... continued below

With the linac-type machines SLC at Stanford and CEBAF in Virginia, experiments with polarized electrons will be possible.
