The SPARC project at Commonwealth Fusion Systems (CFS) is a tokamak system designed to demonstrate commercially relevant fusion energy and achieve net fusion power output during the first operating campaign, with eventual pulse energies exceeding 1 GJ. The SPARC tokamak includes eight magnet systems, three of which utilize high temperature superconducting (HTS) tapes, cooled by the SPARC...
The Proton Improvement Plan-II (PIP-II) is a major upgrade to the Fermilab accelerator complex, featuring a new 800-MeV Superconducting Radio-Frequency (SRF) linear accelerator (LINAC) powering the accelerator complex to provide the world’s most intense high-energy neutrino beam. The PIP-II Linac consists of 23 SRF cryomodules operating at 2K, 5K, and 40K temperature levels supplied by a...
MYRRHA at SCK CEN in Mol/Belgium will be the world’s first large-scale Accelerator Driven System (ADS) at power levels scalable to industrial systems for unparalleled research opportunities in spent nuclear fuel, nuclear medicine, and fundamental and applied physics. MYRRHA was approved by the Belgian government in 2018, releasing the funding for a first phase of staged implementation and...
The cryogenic plant operating 10+ years at the National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory (BNL) and supplying the liquid Helium for three superconducting Radio Frequency cavities. The objective is the continuous Helium supply without interrupting operation. This paper outlines our experience in troubleshooting of various failures of the cryogenic plant and...
Air Liquide Advanced Technologies is pleased to share the results and lessons learnt through the start-up of SLAC 2K cryogenic module. 2K temperature is reached by pumping down the accelerator cavities filled with liquid helium to subatmospheric pressure. In order to pump the cavities down to 30 mbara, a train of 5 high speed cold compressors on magnetic bearings is used. Magnetic bearings...
Helium cryogenic systems operating below the normal boiling point (of 4.22 K) are required for many modern high-energy particle accelerators to achieve the necessary performance criteria. Temperatures below the normal boiling point are established by lowering saturation pressure below atmospheric conditions using vacuum equipment. FRIB operates a multi-stage string of cryogenic compressors (or...
