Working toward a failure free machine
KEKB and its successor, SuperKEKB, are double-ring, e+e- colliders made for producing B mesons. The construction of KEKB started in 1994, utilizing the existing 3 km circumference tunnel of TRISTAN, a single-ring e+e- collider. KEKB commissioning started in 1998, and lasted until June 2010. KEKB’s max peak luminosity, 2.11×10^34/cm^2/s, remains as the current world record. The magnet system...
The beam commissioning of the J-PARC 3 GeV Rapid Cycling Synchrotron (RCS) has been started since 2007, and the proton beams were delivered to a neutron target and a main ring synchrotron on Dec. 2008. At the beginning of RCS operation, an availability of RCS was depressed by a discharge of a thyratron which used in a power supply system of the extraction kicker magnet. We investigated the...
The 12GeV upgrade at Jefferson Lab doubled the energy reach of the lab’s recirculating accelerator. To meet the upgrade requirements, ten new C100 style cryomodules were added to the linacs to supply the additional energy reach. Each C100 was designed to provide 100MeV of acceleration capability plus a 10% margin; twice that of 6GeV era cryomodules . Acceptance testing of the first C100 showed...
