Paper Abstract

The space charge effects in the magnetic focusing femtosecond streak tube have been analyzed by some experiments and computer simulations. The computer simulations have been very precisely performed, especially with respect to obtaining the transient and three dimensional solution. The results have shown that the accumulation of space charge effects between the photocathode and the deflection electrode induces the broadening of the emitted photoelectron packet along the tube axis and it seriously degrades the temporal resolution at high intensity light level in femtosecond range. The detail mechanism of space charge temporal broadening has been clarified. The improvement method of the broadening is referred, too.
