Abstract
A maximal electron current in a neutralized electron beam is constrained by the beam-drift instability of the primary electrons and the neutralizing i ons. To suppress this instability and to increase the threshold of the elec tron current, the active methods are usually used. As a result of the appli cation of these methods the spectrum of neutralizing ions is changed. The m easurement of the ion mass spectrum is performed with the special ion mass analyzer. The experiments on the JINR test bench show that the presence of light ions (hydrogen) in the beam decreases the threshold beam current rela ted to the beam-drift instability.
