Theoretical analysis of a time focus and time amplifier cavity in streak tube

Double-mode electrostatic dispersing prism for electron pulse time-domain compression

“…More has been done theoretically and experimentally to obtain femtosecond or even attosecond electron pulse [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The techniques available now can be classified into two types.…”

“…For the first type the electron pulse duration is modulated with spatially nonhomogeneous stationary electromagnetic field provided by specifically devised electron-optical system [8,9,21,22], such as introducing the accelerating element in the traditional photoelectron gun [9]. In contrast to the first type, the electronpulse-duration modulation is accomplished by non-stationary electromagnetic field for the second one [10][11][12][13][14][15][16][17][18][19][20][23][24][25], in which electrons in different portion are subject to differential velocity (or energy) modulation. With these methods, progress has indeed been made theoretically on the time-resolved performance of UED.…”
