Abstract
A method is described of plotting the light-time curves of flash-discharge tubes using purely photographic methods. Particular attention is given to tubes with flashes of the order of 5- to 10-μsec effective duration, but some results for longer duration tubes are included. The method has been employed to examine for a certain tube the influence on the effective photographic duration of the use of emulsions of widely different spectral sensitivity and speed. For the particular emulsions chosen the observed differences in effective flash duration are of small magnitude and insignificant in practice. Some observations are included of the influence of different capacities on total photographically effective light output (i.e. efficiency). The changes in duration and efficiency resulting from some different gas fillings in tubes which are otherwise identical are also recorded.
