  The European Synchrotron Radiation Facility (ESRF) is presently midway through the Upgrade Programme Phase I (2009-2015), which concerns its infrastructure, beamlines and X-ray source. This paper reports on the present operation performance of the source, highlighting the more recent developments. In this context, 8 insertion device straight sections have been lengthened from five to six metres; two of them operating with canted undulators. The lattice of one cell has been modified for a further increase to 7 metres allowing the test of a mini beta optics and latter the distribution of cavities. A second cryogenic permanent magnet undulator has been completed, which gives a factor of more than 2 in flux at high energy. The booster klystron-based radio frequency transmitter has been replaced by high power solid state amplifiers. Out of three prototypes of HOM damped cavities working at room temperature which have been received and tested, one has been successfully commissioned with beam. Subsequent to the upgrade of the beam position monitor system, a new orbit feedback has substantially reduced the orbit distortion induced by ID gap motions.

  Four years after the launch of the Upgrade Programme, the ESRF is midway through its first phase (2009-2015) and has defined the objectives for the ensuing second phase. The first phase paved the way to a new generation of nano-beam X-ray beamlines fed by an X-ray source itself substantially improved in terms of reliability, stability and brilliance. The second phase envisions a major upgrade of the source to best serve the science case of this new generation of beamlines. In December 2012, the ESRF Council endorsed Management's proposal to launch the technical design study of a new 7-bend achromat lattice. This new configuration will allow the ESRF storage ring to operate with a decrease in horizontal emittance by a factor of about 30 and a consequent increase in brilliance and coherence of the photon beam. The increase will be substantially higher at X-ray energies larger than 50 keV.

TUOCB201 Recent Developments of Novel Beam Diagnostics at the ESRF 1143

  A number of rather novel and particular electron beam diagnostics have seen their development in 2012 for the ESRF Storage Ring. A vertical Beam Halo detector that measures the bunch population at millimetres, i.e. hundreds of σs of nominal beam size, away from the central core. This measurement is based on X-ray synchrotron radiation from a bending magnet and is totally non-destructive to the electron beam itself. Another diagnostic use of the very hard X-rays available from the bending magnets is the detection of electron beam energy fluctuations. The detector hardware is simple and in-expensive and has shown a resolution of energy fluctuations of less than 10ppm. Also a single orbit turn measurement of the injected beam shape and size is now possible through the use of visible synchrotron light combined with a fast gateable intensifier, which can be triggered on any of the desired orbit turns after injection. Detailed results of each of these new diagnostics will be presented.
