Abstract

A program is developed to collect accelerator data using a high speed digitizer and to display data for beam diagnostics. The digitizer has speed up to 2 Gs/s and is multiply retriggerable up to 1024 traces. The signal can be from either wall current monitor for longitudinal dynamics or the strip-line detector for transverse dynamics. The FFT spectral analysis of individual data trace gives the frequency composition of the signal from a train of beam bunches. The FFT analysis of transposed data gives the spectral composition down to sub-synchrotron frequencies. The data is displayed as a plot of single trace, mountain ranges, or 2-dimensional contours to give different perspectives. The physics examples are given
