Paper Abstract

The dynamic performance of Picoframe I, II type framing cameras in both single-frame and double-frame operation have been evaluated theoretically and compared with the corresponding experimental observations. Relevant methods of theoretical computationally-based simulations are reviewed where predictions relating to image position, magnification, spatial and temporal modulation transfer functions and photoelectron transmission through the apertures are provided. From the simulations of photoelectron trajectories in the entire image tube during the framing operation it can be readily deduced that the electron-optical focusing characteristics are influenced significantly by the dynamic fringe-field effects at the deflectors. This is shown to be a major factor in determining the limiting dynamic spatial resolutions and frame times for these particular designs of framing camera. Possible methods for compensating or alleviating this deficiency have been outlined and some preliminary experimental confirmation has been included. Particular emphasis is directed towards Picoframe cameras having ultraviolet and x-ray spectral sensitivities.
