We review the beam performance of all the operational machines in the accelerator complex in 2008, look into the problems encountered, and report case by case on the current status and readiness for 2009 beam production.

2009 will be a very challenging year for the CERN accelerator complex. The clear priority will be the LHC with a run through the winter into 2010 scheduled. The implications of this are discussed. The complex will also have to deliver beam in the normal physics schedule to a plethora of other clients. These clients are enumerated and their required beam is detailed. The machine development...

The Multi-Turn Extraction has been commissioned during the 2008 run of the PS. Both single- and multi-bunch beams with a total intensity of up to 1.4×10^13 protons have been extracted with efficiencies up to 98%. Furthermore, injection tests in the SPS were performed, with the beam then accelerated and extracted to produce neutrinos for the CNGS experiments. The detailed measurements performed...

A report will be given on the performance and issues of the beam instrumentation available to support machine operation throughout the CERN accelerator complex apart from the LHC. Difficulties of machine operation due to instrumentation problems will be highlighted.

The accelerator chain encountered different problems related to the controls system in the large sense of the word. This presentation will give an overview of the issues concerned together with the applied solutions, where applicable, for the whole accelerator chain apart from the LHC. In the cases where no solutions were found or implemented, the issues will be addressed in more detail in...

During the 2008 startup, the pbar production efficiency was unusually low. Despite several tuning attempts during the run, peak values such as observed in 2007 were never reached and typical beam intensities stayed below numbers of previous years. Here we will discuss the possible causes, what was done in 2008 and what could be done during this years startup in order to improve AD performance.
