Operation and recent developments at the ESRF

The ESRF has been operating for more than 10 years. As a result of the maintenance policy a high level of beam availability as well as a long beam time between failures has been maintained. In addition, a continuous effort is made to develop the machine further. The operation status and the experience gained with the recent upgrades are reported. It concerns: a) The successful operation with 5 in-vacuum undulators operated at a 5-6 mm magnetic gap; b) The implementation of a new hybrid type filling pattern which combines groups of bunches at full current and single bunch; c) The successful qualification of a 5 metre-long, 8 mm vertical aperture insertion device (ID) aluminum chamber coated with nonevaporable getter material; d) The evolution of the impedance with associated consequences on instability thresholds, following the installation of a number of low aperture insertion device chambers; e) The successful test of the SOLEIL superconducting cavity; f) The injection front end open in order to ensure a better thermal stability in the beamlines.
