With the purpose of enhancing the efficiency of adjusting xenon flash lamp working as we expect

we studied the relationship between peak currents and charging voltages and quantitatively analyzed the influences of parameters of xenon flash lamps on peak currents. We measured the peak current through flash lamps working under varied voltages in charge capacitor with different filling pressures

arc lengths or bore diameters. The results show that the peak currents have linear relationship with the voltages ranging from 1.75 k V to 4.25 k V. The relative errors between the experimental data and linear simulation data are less than 5%. By calculation and analysis on relationship between the slopes and filling pressures

arc lengths and bore diameters respectively

it has been proved that the linear relationship is correct and that the research method is reasonable

so this is a new approach to research the peak current through xenon flash lamps. It is also found out that the peak currents are influenced most by bore diameters

but least by filling pressures. The results have a great significance in developing

selecting

and adjusting new xenon flash lamps.
