Abstract
A large space-charge is detrimental to the cooling process of a dense beam, Generation of a neutralised electron beam is restricted by beam- drift instability. To suppress this instability, active methods are us ed: a kicker with a transverse electric field (shaker) and longitudina l electrodes placed in the vacuum chamber and in the gun region expel secondary electrons. Results of experiments dedicated to the developme nt of beam stabilisation on the JINR test bench and in the electron co oling system at LEAR are discussed.
