Impurity increase in single bunch mode of UVSOR and its cure

  • 1. Hiroshima Univ. (Japan)

Description

An increase in impurity was observed in the single bunch mode of the UVSOR storage ring. This phenomenon is caused by electrons thrown out of the bucket by the Touschek effect begin recaptured by the following buckets due to the radiation damping. It is successfully cured with a beam scraper system that promptly damps electrons thrown out with a momentum gain greater than a certain amount. The other possible mechanism of impurity increase is also discussed. (author)
