. INTRODUCTIOILCoulomb interaction in electron beam is one of the main factor limiting maximum time resolution of subpicosecond image converter tubes. Among the investigations devoted to theoretical analysis of this problem one can distinguish two different approaches. In one of them1 the simplified model concept for the beam motion equations is treated in order to estimate the typical system parameters within the accuracy of one order of magnitude . Such approach can not give the detailed characterization of the beam structure required for formation of space-time modulation transfer function (MTF).Another approach2 is related to the analysis of closed system of equations describing the initial boundary nonstationary selfcoordinated problem for electron beam. It is well known that in general case the correct numerical solution of a such kind problem may be obtained only by application of rather complicated and massive numerical procedure which realization is difficult even for modern powerful computers. 0-81 94-0809-3/92/$4.00

“…In the pioneering work by Zavoisky and Fanchenko, 1,2 the first analytical estimations on these effects were carried out, and then during the 1980s a number of authors directed their efforts to refine these results by using more sophisticated theoretical and numerical models. [3][4][5][6][7][8][9] Among these papers, the paper by Kinoshita et al 9 should be specially mentioned; it contains probably the most accurate and exhaustive computer simulation on space charge effects that has been undertaken so far. Nevertheless, some questions connected with the problem remain open.…”

Computer techniques and software are developed to study the dynamics of electron packets on a subpicosecond time scale in streak image tubes and photoelectron diffractometers. It is shown that the Coulomb spread of an electron packet substantially increases for a sufficiently narrow energy distribution of photoelectrons, due to disintegrative space charge effects inside the packet. © 1998 Society of PhotoOptical Instrumentation Engineers.
