Description
Summary:The effect of bunch slippage in stimulated superradiance emitted from short electron bunches in an undulator channel at the off-grazing resonance is discussed. Comparison between off-grazing and grazing resonance emissions shows that the emitted power in the early radiation-build-up stage significantly decreases owing to the bandwidth restriction caused by slippage. The influence of bunch-pulse detachment due to the slippage seems to be minimized by the proper positioning of the excited pulse.
