The Deep Underground Neutrino Experiment (DUNE) is an international flagship venture to unlock the mysteries of neutrinos. Hosted at the Sanford Underground Research Facility (SURF) and supported by the Long-Baseline Neutrino Facility (LBNF), DUNE relies on nearly 70,000 tonnes of ultrapure liquid argon (LAr) housed in state-of-the-art cryostats. Transporting such vast quantities of LAr to its...
The Sanford Underground Research Facility (SURF) will host the Far Detectors of the Deep Underground Neutrino Experiment (DUNE), an international multi-kiloton Long-Baseline neutrino experiment that will be installed about a mile underground in Lead, SD. Detectors will be located inside four cryostats filled with almost 70,000 metric tons of ultrapure liquid argon, with a level of impurities...
The Mainz Energy-recovering Superconducting Accelerator (MESA) is an electron accelerator currently under construction at the Institute of Nuclear Physics, Johannes Gutenberg University Mainz, Germany. MESA is designed as a superconducting multi-turn energy recovery linac (ERL) to provide high-intensity, low-energy electron beams for precision electron scattering experiments testing the limits...
The Second Target Station (STS) at Oak Ridge National Laboratory will be a 700 kW pulsed spallation neutron source optimized to deliver 18 high brightness cold neutron beams. To supply the optimum neutron performance, two compact liquid hydrogen moderators are located in the peak neutron production zones, immediately above and below the rotating tungsten spallation target, resulting in a...
LCLS-II HE project will increase the energy of the CW-SCRF linac from 4 to 8 GeV, enabling the photon energy range to be extended to at least 13 keV and potentially up to 20 keV at 1 MHz repetition rates. HE’s Cryogenic Distribution System (CDS) will connect existing Cryoplant 1&2 to 23 new HE cryomodules. Reference designs have been completed for all components. Current status of the CDS will...
Michigan State University (MSU) has refurbished the superconducting K500 cyclotron and installed it as the heart of a new semiconductor / electronic chip testing facility at the Facility for Rare Isotope Beams (FRIB). The K500 cyclotron used to be a part of the Coupled Cyclotron Facility (CCF) at MSU but was decommissioned in 2020 following the reconfiguration of the beamlines for the FRIB...
The Electron-Ion Collider (EIC) at Brookhaven National Laboratory (BNL) will involve superfluid helium cooling of superconducting magnets and Superconducting Radio Frequency (SRF) cavities at several sites around the existing Relativistic Heavy Ion Collider (RHIC) accelerator tunnel. While the majority of the cooling power for these loads is provided by BNL’s central cryogenic plant, Jefferson...
A new helium liquefaction system with high capacity is under design and will be built at the Lawrence Berkeley National Laboratory (LBL) in the next couple of years to replace a 43 years old liquefier. The new liquefaction system will provide at least a mixed 80 liter per hour liquefaction rate and 35 W refrigeration capacity at 4.5K without liquid nitrogen pre-cooling, or a mixed 140 liter...
