Accelerator Support Systems
- Kathleen Genge (TRIUMF)
Description
Reliable operation of accelerators requires reliable infrastructure support systems. This session explores the interface of these systems with accelerator systems as well as issues and optimization associated with them. Some of these areas include interfaces between cryogenics and plant operation, cooling and ventilation, electrical infrastructure and power quality, diesel and UPS backup power systems and power converters. Maintenance, disruption or malfunction of the utilities can lead to large impact on the accelerators in terms of downtime, reliability, and performance if no end-to-end approach is considered. In this session, feedback is welcome as well as means and strategies to make the accelerator components more resilient to support system disruptions (redundancy, backup system, harmonic filtering, UPS, training, etc.) and to shorten recovery time.
The Spallation Neutron Source (SNS) started operations in 2007 after extensive equipment commissioning. Electrical Power Conversion (EPC) equipment was originally specified or designed by different national laboratories and manufactured by various vendors. The equipment includes Low Energy Beam Transport (LEBT) chopper pulsers, High Voltage Converter Modulators (HVCMs), DC magnet power...
CERN operates and maintains several large cryogenic systems with complex architecture necessary for the operation of the Large Hadron Collider (LHC). Continuous operation of the accelerator during Run2, and the implementation of availability calculation tools as well as the use of a fault tracking system on cryogenics equipment, has allowed the CERN cryogenics team to gain valuable experience...
TRIUMF is heavily reliant on supplies of liquid helium and liquid nitrogen to maintain operations. The Cyclotron uses bulk LN2 and a Linde 1630 helium refrigerator to support the vacuum system. There are two superconducting LINAC’s at TRIUMF as well. Both use LN2 to cool the necessary 80K thermal shields. There are three Helium Refrigeration cold boxes to supply LHe for the cryomodules. The...
