40. Coulomb Blockade Thermometer: a primary device for sub-kelvin measurements

Matthias Meschke (Aalto University)

Coulomb blockade thermometry (CBT) is a well-established method for a precise and primary determination of cryogenic temperatures from below 5 mK to a few tens of kelvins. In practical devices, the operation of CBT is based on single electron charging effects in arrays of about 1000 normal metal tunnel junctions and relates temperature directly to a conveniently measurable voltage signal. I...

37. Instrumentation for cryogenics at CERN

Juan Casas-Cubillos (CERN)

The controls and instrumentation infrastructure at CERN is strongly dependent on whether radiation is present or not. The former concerns typically the refrigerators and its associated infrastructure, these are procured as turn-key facilities and most instruments are standard commercial parts.
Radiation constraints on the other hand impose a complicated quality assurance policy. CERN...

39. Optical Fiber Sensors for Cryogenic applications

Dr Daniele Inaudi (Smartec)

In the framework of ongoing projects with CERN and ITER magnet divisions SMARTEC has developed, qualified and serially produced a number of different fibre optic sensors, including:
- Strain sensors
- Displacement sensors, short and long range
- Non contact, remote, long range displacement sensors
- Local temperature sensors
- Distributed temperature sensors
- Multi-fibre...

51. Superconducting devices based on Josephson junctions for metrology and general instrumentation

Jörn Beyer (Physikalisch-Technische Bundesanstalt)

The discovery of tunnelling supercurrents in the 1960s initiated the development of superconducting electronic devices that employ Josephson junctions as their key functional elements. At PTB, Superconducting Quantum Interference Devices (SQUIDs) and Josephson Quantum Voltage Sources (JQVSs) are being developed and reliably fabricated using thin film technologies. They can be operated in...

41. The application of the PED on the design codes for cryogenic equipment, and future developments foreseen in this field

Dr Herve Barthelemy (Air Liquide)

Following a brief background review, we will go through the benefits and drawbacks of the PED for the industry. Main changes compared to the old national regulations and to the recently published new version (2014) will be considered as well as the notified body, category and module.
Moreover, European and International standards published or in preparation for cryogenic vessels, accessories...
