13- Insuring Long Term Reliability
- Doug Preddy (TRIUMF)
Jefferson Lab’s Continuous Electron Beam Accelerator Facility (CEBAF) has moved into production running after completing the 12 GeV upgrade. In many instances, new equipment has been integrated into the original CEBAF infrastructure and systems. Some challenges and opportunities have presented themselves during and following commissioning of the "new" machine that have prompted Jefferson Lab...
In 2010, FGC2 failure rate predictions based on LHC failure data have shown a need for a new radiation-tolerant power converter controller. For the new system, the electrical reliability and radiation-induced failure rate requirements were defined to achieve a target reliability for the HL-LHC era.
This talk will present main steps of the FGClite design: form specification, prototyping and...
Long term reliability is critical for any successful particle accelerator operation. The Relativistic Heavy Ion Collider (RHIC) is now faced with a reliability challenge owing to age, continual performance improvements, and even best practice design considerations. This presentation will focus on our experience with the RHIC quench protection diodes; a passive part of the machine protection...
The K1200 cyclotron is part of the Coupled Cyclotron Facility (CCF) at National Superconducting Cyclotron Laboratory (NSCL). It was built starting in 1987 and produced its first standalone beam in 1989. The expected life of the K1200 was estimated to be 20 years. In 2017, 28 years first beam, the K1200 continues to produce extremely useful science. As the cyclotrons age, maintaining their...
