Abstract Designing, building, commissioning, operating and maintaining multiple complex cryogenics process control systems involves many challenges. For several years, CERN has developed various solutions to help with the whole lifecycle of a cryogenic system. This allowed production quality highly reliable electrical systems. paper will present use these innovative automated tools their evolut...

The ATLAS detector requires a huge infrastructure consisting of numerous interconnected systems forming complex mesh which undergoes constant maintenance and upgrades. Technical Coordination Expert System provides, by the means user interface, quick deep understanding infrastructure, helps to plan interventions foreseeing unexpected consequences, understand events when time is crucial in contro...

A novel hybrid superconducting coupling (NHSC) is proposed in this paper, which the secondary composed of copper and a split superconductor. magnetic equivalent circuit (MEC) model presented to analyze calculate distribution field torque characteristics. The 3D modeling considers end effects encountered mating. expressions flux are obtained by combining Kirchhoff’s law Ampere’s lo...

Lithium metal has been considered the "holy grail" anode material for rechargeable batteries despite the fact that its dendritic growth and low Coulombic efficiency (CE) have crippled its practical use for decades. Its high chemical reactivity and low stability make it difficult to explore the intrinsic chemical and physical properties of the electrochemically deposited lithium (EDLi) and its a...

The Large Hadron Collider (LHC), a 26.7 km circumference superconducting accelerator equipped with high-field magnets operating in superfluid helium below 1.9 K, has now fully entered construction at CERN, the European Laboratory for Particle Physics. The heart of the LHC cryogenic system is the quasi-isothermal magnet cooling scheme, in which flowing two-phase saturated superfluid helium remov...

Liquified natural gas (LNG) is a clean primary energy source that growing in popularity due to the distance between (NG)-producing countries and importing countries. The large amount of cold stored LNG presents an opportunity for sustainable technologies recover utilize this energy. This can enhance efficiency regasification terminals economic viability supply chain. form low temperatures refer...

In this paper, we study static bistability and mechanical cooling of a dissipative optomechanical cavity filled with Kerr medium. The system exhibits optical for wide input-power range the power threshold being greatly reduced, in contrast to case purely coupling. At bistable regime, membrane can be effectively cooled down few millikelvin from room temperature under unresolved sideband conditio...
