The report covers the work conducted to obtain in absolute units the spectral distribution of a 10-kilowatt, xenon, compact arc lamp. The wavelength range of these measurements was selected between 2,400 and 11,000 Angstroms A at four different power levels 2.6, 5, 7.5, and 10 kilowatts. The results were obtained in absolute units of radiance wattssteradian sq cm1 A interval. The report concludes that 1 The highest radiance was between 800 and 900 millimicrons. 2 The blackbody temperature producing the same radiance at 0.8232 micron as on the xenon spectrum was 9775K. 3 The connection between total radiated energy from 0.2 micron and 1.1 microns and lamp power is, within the measured range, almost linear. 4 With increasing lamp power, increased line broadening and continuum appear as is to be expected.
