A prototype Energy Recovery Linac (ERL) has been proposed and schematic design of the facility is underway. Such a facility necessarily involves the juxtaposition of extremely sensitive superconducting RF cavities and the noisy and powerful motors and compressors used to make the liquid helium the cavity needs. In this paper we give preliminary consideration to the possible deleterious effects ...

KAGRA is the first km-scale gravitational wave detector to be constructed underground and employ cryogenics cool down its test masses. While location provides a quiet site with low seismic noise, cooling infrastructure known generate large mechanical vibrations due cryocooler operation structural resonances of cryostat. As system components are relatively heavy in close proximity masses, oscill...

Nowadays, to reach progressive growth although being competitive in the market, manufacturing industries are using advanced technologies such as cloud computing, Internet of things (IoT), artificial intelligence, 3D printer, nanotechnology, cryogenics, robotics, and automation smart sectors. One subclass intelligence is machine learning, which uses a computer system for making predictions perfo...

Abstract An important cryogenic equipment of the Large Hadron Collider (LHC) consists in electrical distribution feedboxes (DFBs) which are used to power superconducting magnets accelerator. These contain current leads achieving transition between copper cables at ambient temperature Niobium-Titanium wires temperature, immersed a liquid helium bath 4.5 K. This must be regulated defined level al...

Abstract Cryogenics has an important influence on industry and science. In this study, optimum working conditions are obtained by applying exergy analysis local optimization methods to two- three-stage vapor compression cascade cryogenic cycle. The first second laws of thermodynamics, analysis, applied the By considering needs demands, it is possible create new cycles adding devices and/or stag...

We have constructed a versatile current to voltage (I-V ) converter operating at liquid helium temperature, using a commercially available all-CMOS OPamp. It is valuable for cryogenic measurements of electrical current of nano-pico amperes, for example, in scanning probe microscopy. The I-V converter is thermally linked to liquid helium bath and self-heated up to 10.7 K. We have confirmed its c...
