Abstract: Importance of sheet beam technology and role of space charge field analysis for success of this technology have been studied. Space charge field of sheet electron beam has been investigated in three approaches. At first a simplified infinite width sheet and line model are given to investigate nature of variation of field, then analysis is done for finite width beam. Using a theoretical model in OPERA 3-D, simulation has been done to compare space charge field. Space charge field of sheet electron beam is compared with that for equivalent round beam. Interpretation is made about nature of space charge field and its impact to sheet beam transport. Importance of proper optimization of beam height has been emphasized.
