On some limitations on temporal resolution in imaging subpicosecond photoelectronics

Numerical modelling is used to analyse some effects restricting the enhancement of temporal resolution into the area better than in streak image tubes and photoelectron guns. A particular attention is paid to broadening of an electron bunch as a result of Coulomb interaction. Possible ways to overco...

Description
Summary:Numerical modelling is used to analyse some effects restricting the enhancement of temporal resolution into the area better than in streak image tubes and photoelectron guns. A particular attention is paid to broadening of an electron bunch as a result of Coulomb interaction. Possible ways to overcome the limitations under consideration are discussed.
