The CERN Accelerator Complex for protons consists of a chain of 5 accelerators from LINAC4 to the LHC, in which any machine fault will affect the downstream chain. Availability is key for efficient operation of the complex. Recently, the CERN Accelerator Fault Tracking (AFT) system was complemented by a automatic fault recording system, including fault detection, root cause identification, and...
The SOLEIL synchrotron is the French 3rd generation synchrotron light source. In operation since 2007, it supplies photon beams to 29 beamlines with a maximum intensity of 500 mA, 5000 hours per year.
After spending the first ten years improving the reliability of our equipment, we are getting closer to our goal, which is: 99% availability of the photon beams and 100 hours MTBF. We are...
The Spallation Neutron Source (SNS) is the highest power pulsed accelerator driven neutron source in the world delivering 1.7 MW of beam power with a capability up to 2.8 MW. One of the metrics monitored daily is beam availability. For a neutron source high beam reliability is extremely difficult due to the accelerator high beam power and tight interlock requirements required to minimize...
