Status report on the synchrotron radiation source ‘‘SIBERIA’’ at the I. V. Kurchatov Institute of Atomic Energy

The 450‐MeV electron storage ring SIBERIA‐1 with 100‐mA stored beam current was put into operation at the I. V. Kurchatov Institute of Atomic Energy in 1983. In 1984 a 3‐pole superconducting wiggler was placed in the storage ring, which produced SR beams with a critical wavelength 21 Å. Investigations of phosphor‐crystal and high‐temperature superconductor luminescence, VUV‐spectrometry of wide‐band dielectrics, photoelectron spectroscopy of HTSC, etc. are being carried out. A 2.5‐GeV 100‐mA electron storage ring, SIBERIA‐2, is now under construction.
