Book Description
The emission of high-current microsecond-arc channels with a 1-mm gap has been studied in argon and helium by means of a 20-nsec Kerr-cell shutter and profiles of the relative luminance B determined from photographs of the arc image. The method is practically unaffected by instabilities in arc position, and the accuracy of relative luminance values has been perfected to a scatter smaller than plus or minus 5%. From maximum values of the 'saturation' luminance B* in the axis of the arc channel observed over a wide range of arc current altered by the gas pressure, a ratio of B*He/B*A = 1.52 for the two gases has been determined. The luminance profile across the arc channel demonstrates increasing opacity after saturation is reached. (Author).
