Experiments on a single accelerator section showed that pulse-shortening occurs in the output electron pulse first at the high-energy end of the accelerator wave guide. The current at which pulse-shortening occurs is proportional to the r-f power level in the accelerator tube. A constantfield accelerator constructed to operate at the x-band yielded currents in excess of 100 ma without showing pulse shortening as compared to 40 ma for the equivalent constant-impedance design. A field effect associated with low values of field in the normal mode or higher order spurious r-f modes may be responsible for the pulse shortening.
