BRV-continuum source as a radiometric transfer standard between 40 nm and 600 nm

The BRV-continuum source was investigated for its potential use as a radiometric transfer standard in the wavelength region from 40 to 600 nm. Variations of the spectral radiance from one pulse to the other up to a factor of 3 are possible, but the mean value of more than 15 pulses in general is reproducible within 15%. The time-integrated spectral radiance of the pulses shows a wavelength dependence proportional to lambda(-2.5) for lambda > 100 nm and is proportional to lambda(-2.1) around 50 nm.
