Abstract :
We report on measurements of the bunch energy spectrum at the end of the SLAC linac. Using the spectra obtained for two different linac RF phases we obtain both the bunch induced voltage and the longitudinal distribution of the bunch. The measurement results are compared with theoretical predictions. In particular, the induced voltage is in good agreement with that obtained using the calculated wake function for the SLAC linac. This measurement technique may be useful for monitoring changes of the linac bunch shape in the SLC
