The ESRF Upgrade Programme..

• Beamline Upgrade
• Development of Scientific Partnership
• Extension of the building infrastructures
• Accelerator System Upgrade
• Replacement of klystron by solid state amplifiers
• New HOM damped RF cavities suitable for 300 mA
  ring operation
• New Orbit measurement and feedback system
• ..

224 Libera Brilliance since March 2009

• 10 Hz orbit acquisition
• Bunch by bunch acquisition
• 10 kHz orbit driving DC-AC orbit correction

• A major accelerator system, i.e. BPM electronics
  is now based on the same system all over the
  world.
• It is important that the users of this Libera
  system exchange their experiences and trigger
  improvements and new developments.
