文摘

A method of measuring energy spectrum of synchrotron radiation (SR) based on attenuation is described in this paper. Tikhonov regularized method is applied to reconstruct the spectral distribution of SR. The feasibility of the method is studied in detail by using a hypothetical SR spectrum. The applied results of the spectrum of 4W1B beamline in BSRF (Beijing Synchrotron Radiation Facility) are shown.
