The RF fundamental power coupler (FPC) in SRF accelerating systems can have a major contribution to the cryogenic power consumption. In the framework of the FCC feasibility study, the focus on the energy saving is of primary importance given the size of the machine, with 264 cavities at 400MHz and 488 cavities at 800MHz for the collider, and 600 cavities at 800MHz for the booster, at the ttbar...
In Munich, Germany, a 15 km long superconducting power cable is planned to provide a high-power connection within the 110 kV network. To ensure safe and economic operation, efficient liquid nitrogen re-cooling stations are needed at several points along the cable. Within the SuperLink research project, next generation cooling systems for such operations are being developed.
As an alternative...
Shenzhen Superconducting Soft-X-ray Free Electron Laser (S3FEL), located at Shenzhen, China, aims to construct a new light source that can generate high brightness X-Ray pulses between 40 eV and 1 keV at repetition rate up to 1 MHz. The S3FEL is based on superconducting accelerator technology comprised of 25 cryomodules (CMs) operating at 2 K temperature with 5 K thermal intercept circuit and...
The structured packing is one of the core internals in the cryogenic distillation column. In the past, testing and development of packings were mostly based on ambient hydraulics and fluids, which may deviate considerably from actual cryogenic testing. Therefore, it is necessary to reveal the falling film flow characteristics of cryogenic fluid on the surface of structured packing and study...
Cryopreservation technique of living tissue and cells is used in long term storage and transportation. Human ES / iPS cells could be useful in regenerative medicine. During cryopreservation of human ES cells, there is a problem that the survival rate after freezing and thawing process is low compared with mouse ES cells. The survival rate of these cells after cryopreservation process...
Low-field (<10mT) Magnetic Resonance Imaging (MRI) opens the possibility to perform medical imaging at a fraction of the cost of conventional MRI. As signal vanishes with lower applied magnetic field, it becomes necessary to use an ultra-sensitive and ultra-low noise detector to acquire medically relevant images in a reasonable time. Thanks to their exceptional noise performances,...
While the search for novel superconductors toward higher current carrying capacities and lower transport losses in different types of superconducting wires continues, so far, there is no record of any “liquid superconductor”.
Superfluid helium, however, “conducts” heat without thermal resistance due to its very high thermal conductivity below its Lambda transition point.
For superconducting...
At IPR, in Steady State Superconducting Tokamak (SST-1), cryogenic division have two sections, one is 4.2 K and other 77 K temperature that is used for cooling of superconducting magnet material coils and for reduction of heat loads etc. The working at cryogenic temperature and high pressure environment is drastically different than working at room temperature, the material behaviour, its...
