Streak tube characterization
An explanation is given of some of the phenomena that occur in electrostatically focused streak tubes and how they can affect various measurements. These phenomena have to do with the overall tube voltage (cathode to anode/screen), cathode resistivity, space charge effects, chromatic effects (those caused by the spread in energy distribution of photoelectrons), off-axis focus, deflection defocusing, and the phosphor screen. Some important static and dynamic streak tube measurements are then described. The static measurements include those of photocathode spectral sensitivity and uniformity, phosphor screen measurements, tube radiant gain, extinction ratio, static resolution, magnification, and distortion. The dynamic measurements include spatial and time resolution. (LEW)
