Produktinformationen "Accelerators 2015"
Regarding DESY’s accelerator construction, operation and research activities, the year 2015 was again a very busy and successful year. The PETRA III synchrotron radiation source was recommissioned after a long shutdown to implement the photon beamline extension project in the northern and eastern sections of the storage ring. Photon beam delivery to the users restarted as planned in April. The pre-accelerators had been put back into operation earlier so that the high-energy test beams at the DESY II synchrotron had become available to users from the particle physics community already in January. The operation of PETRA III went well from the start and, except for an expected slight increase in beam emittance due to the lattice modifications and the necessity for vacuum conditioning, did not show significantly different behaviour from the one before the extension project. The facility achieved its availability goal of 95% by the end of the 2015 user run period. Trips of the radio frequency (RF) system in the high bunch charge “timing mode” of operation were reduced by optimising the tuning of the cavities. Still, more issues will have to be addressed in the future to further reduce the downtime to well below the original goal of 5%.
