Torsten Koettig (CERN)23/07/2024, 16:00ICEC 14: New devices and novel conceptsRegular Oral (15m)
One of the cooling concepts of prototype cavity structures for the FCC is based on a self-sustained convection loop (open thermosyphon) with liquid Helium as a cooling fluid. A suggested novel cavity type is named Slotted Waveguide Elliptical Cavity (SWELL) with an estimated heat load for the 1.3 GHz prototype of 70 W. A vertically oriented 131 mm high cooling channel of 30 mm-diameter and...

451. Experimental improvements to the acoustic expander with applications to cryogenic refrigerationJacob Adams23/07/2024, 16:15ICEC 14: New devices and novel conceptsRegular Oral (15m)
The acoustic expander is an innovative cryogenic component that uses gaseous pressure waves for work transfer as part of a continuous flow, recuperative cycle refrigerator. This expander uses passive reed-valves coupled to an acoustic resonator, much like a wind instrument, to produce refrigeration. The passive reed-valves are pressure-controlled by the imposed, static pressure difference...

Cryogenic wind tunnels (CWT) provide a means to perform high Reynolds number aerodynamic tests in a cryogenic environment and simulate hypersonic flights. Non-invasive measurement technology is an advanced measurement techniques applicable to CWT. However, the utilization of non-invasive measurement technology in CWT encounters significant challenges due to the absence of appropriate tracer...

The paper describes the commissioning of a conduction-cooled NbTi magnet system for Superconducting Magnetic Density Separation (SMDS), as well as its preliminary field tests on-location at the industrial end-user. MDS is a relatively new sorting technology that allows to sort multiple non-magnetic materials simultaneously, based on their mass density. A ferrofluid carries a mixed particle...

Large-scale air separation units are pivotal in separating air into gases like nitrogen, oxygen, and argon, crucial for industries such as metallurgy, coal chemical, and petrochemical. However, the high energy consumption of these units keeps operational costs elevated. Moreover, the increasing peak-to-valley ratio in the power grid poses a threat to its stable operation. To address these...

The cryo compatible and helium leak-tight vacuum barrier (VB) is necessary in the superconducting (SC) Tokamak, which is required to separate the vacuum between the machine cryostat and superconducting current feeder system. It is a dissimilar material joint that electrically isolates 2 kV DC voltage during the quenching of SC magnets. The current feeder system, which houses the 4.2 K...

Christopher Lawson (ISIS Neutron and Muon Source)23/07/2024, 17:45ICEC 14: New devices and novel conceptsPoster Presentation (120m)
The dilution refrigerator is a low temperature workhorse, used worldwide to provide temperatures in the millikelvin range for devices ranging from quantum computers through to dark matter detectors. Since its inception more than 50 years ago, the mechanism by which refrigeration occurs has been well understood. However, until this point, the only visual representations of this process were...
