Abstract

Solenoids are frequently used for focusing of the low energy electron beams. In this paper we focus on using these magnets as a nearly universal tool for measuring beam parameters including energy, emittance, and the beam position and angle with respect to the solenoid axis. We describe in detail corresponding procedures as well as experimental results of such measurements.
