Scattering of electrons on thermal radiation photons in electron-positron storage rings

Telnov V. I.

It is shown that Compton scattering on thermal radiation photons restricts the lifetime of high energy electron beams in storage rings to a level of 30 h. At a vacuum pressure of 10-10 Torr the probability that an electron is knocked out from the beam due to scattering on thermal photons exceeds the probability of bremsstrahlung on residual gas ( ΔE E > 1%) by one order of magnitude, i.e. this effect can cause a considerable background in detectors. © 1987.
