The contents are: measure and tuning of accelerating cavities, coupling cavities, measure of quality, field distribution, dispersion curve . and the way of measuring and eliminating the stop band, etc. At the same time, utilizing the test data and the dispersion equation of cavity chain, we make a fit dispersion curve by way of least squares fit, and we work out the width of stop band and the intercavernous coupling coefficient.
