Electron Beam Transport and Emittance Measurements in a Long Periodic Solenoid Channel

An electron beam transport experiment utilizing 5 kV electrons in a 200 mA beam passing through 36 solenoid lenses is described. The fraction of the beam transmitted is a function of the lens strengths, the length of the channel, the beam size, and the precision of the alignment. Emittance measurements in the 36-lens channel showed no significant degradation compared to a 12-lens channel.
