Automatic Data Acquisition

Automatic data acquisition and analysis system is set up aiming at measuring and analyzing the electron beams distribution from electron gun and traveling wave tube. It can obtain electron beam parameters, such as three-dimension current density distribution, beam center, beam waist and total current etc. and it can be applied to space technology ranging from centimeter wave to millimeter wave. LabVIEW program is used to acquire data from the hardware equipment and deduce results from post-processing system. As a result, this study is significant to improve the design of electron gun and traveling wave tube in space application.
