Abstract
The Berlin electron storage ring BESSY can be used as a primary source standard to es-tablish a spectral emission scale. The uncertainty is about 0.23 % in the near infrared and increases to about 2 % in the soft X-ray region at 5 keV. At the radiometric laboratory of PTB at BESSY special beamlines have been built to calibrate transfer source standards utilizing BESSY as a primary standard. Presently laser produced plasmas and high current hollow cathode sources are investigated in respect of their use as transfer source standards. To establish a spectral responsivity scale in the soft X-ray region Si(Li)-detectors are calibrated using undispersed synchrotron radiation. Solid state diodes are calibrated as transfer detector standards by comparison with Si(Li)-detectors. The characterization of optical components can be performed using a reflectometer operating in the 5 nm to 34 nm range.
