Abstract
A new framing-camera tube is capable of recording two-dimensional image frames with high spatial resolution in the sub-100-ps range. Framing is performed by streaking a two-dimensional electron image across narrow slits; the resulting electron line images from the slits are restored into a framed image by a restorer deflector operating synchronously with the dissector deflector. Performance has been demonstrated in a prototype tube by recording 125-ps-duration framed images of 2.5-mm patterns. The limitation in the framing speed is in the external electronic drivers for the deflectors and not in the tube design-characteristics. Shorter frame durations (below 100 ps) can be obtained by use of faster deflection drivers.
