| Zusammenfassung | PTB is setting up a radiometric laboratory at the storage ring BESSY. In the special mode “metrology” of the electron beam optic the beam cross sections and the beam divergences of BESSY are predicted to be sufficiently small and the storage ring parameters can be measured with an accuracy allowing the spectral radiant power Pλ to be calculated with an uncertainty ΔΡλΡλ between 10-2 and 10-3 according to the Schwinger formula. At present three beamlines are under construction. One beamline is dedicated to the detailed investigation of the synchrotron radiation itself with respect to the possible use of BESSY as a standard source of spectral radiant power. At the two other beamlines transfer sources and detectors will be calibrated in the wavelength range between 4 nm and 300 nm. |
