Ion Trapping and Clearing

Ion trapping in the electron beams of future factories is one of the major issues to be addressed. After a brief review of the adverse effects of neutralization in particle storage rings, the basic topics of ion production by ionization of the residual gas are recalled: ion production rate, natural clearing rates, ion kinematics, and conditions of trapping for bunched and unbunched particle beams with positive or negative space charge. Different methods of clearing are described and their performance discussed, namely, d.c. clearing electrodes, empty buckets (in electron storage rings) and beam shaking. Examples of neutralization effects and diagnostics are taken from CERN machines.
