C-17: Safety, reliability and standards
Invited Oral (30min)
The helium cooled magnets of the LHC particle accelerator are installed in a confined space, formed by a 27 km circumference 3.8 m diameter underground tunnel. The vacuum enclosures of the superconducting LHC magnets are protected by a lift plate against excessive overpressure created by eventual leaks from the magnet helium bath, or from the helium supply headers. A three-meter long no stay...

Helium inventory in high energy accelerators, tokamaks and free electron lasers may exceed tens of tons. The gaseous helium is stored in steel tanks under the pressure of 20 bar and at environment temperature. Accidental rupture of any of the tanks filled with the gaseous helium will create a rapid energy release in form of physical blast. An estimation of pressure wave distribution following...

C-16: Instrumentation and process control
Oral presentation (15min)
The magnetic-field fluctuation thermometer (MFFT) is a high-accuracy SQUID-based noise thermometer suitable for sub-Kelvin thermometry. It consists of a highly sensitive low-Tc SQUID magnetometer and a metal body in contact with the temperature stage to be measured. The SQUID is used to inductively detect magnetic field fluctuations that arise from the thermal motion of electrical charges in...

Oral presentation (15min)
The close relationship between industrial energy use and cryogenics drives the need for optimized thermal insulation systems. Emerging cryofuels usage is enabled by adequate isolation of the liquid hydrogen or liquefied natural gas from the ambient environment. Thermal performance data for the total insulation system, as rendered, are essential for both engineering designs and cost-benefit...

C-10: Superconducting current leads and links
Oral presentation (15min)
The Current Lead Test facility Karlsruhe (CuLTKa) has been constructed to optimize the capabilities for current lead testing at the Karlsruhe Institute of Technology (KIT). The facility comprises five cryostat vessels including two test cryostats connected by transfer lines to the 2 kW refrigerator. Each test cryostat holds two current leads with a superconducting short circuit connector. The...
