ABSTRACT
A velocity analyzer of adjustable interelectrode distance has been used to study the space-charge effects on the characteristic curve. The effects become apparent for distances larger than about 10λD. The theoretical analysis considering the trapped ions in the vicinity of the entrance grid leads to a better correlation with the experiments than that omitting them.
