Abstract

The ESRF accelerators have been in full routine operation for more than four years. The source delivers 5600 hours of X-ray beam to nearly 40 beam lines simultaneously. Our first goal is to ensure good availability of the machine as well as a satisfactory mean time between failures (MTBF). A third RF unit has been installed which, amongst other advantages, allows Landau damping from active modulation. A fast global feedback system to reduce the fast distortion of the closed orbit in the vertical plane has been put into operation and is giving results as expected. New filling patterns have been assessed and the machine was successfully operated at 4 GeV (instead of the nominal energy of 6 GeV) in March 1999. Two years ago, several challenging short-term goals were defined. Most of them have been achieved or are actually in progress. The results are given below
