Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

British Cryogenic Cluster Day held in September

A total of 120 attendees took part in the Cryogenic Cluster Day held at the end of September at the UK's Science and Technology Facilities Council Rutherford Appleton Laboratory, at the heart of the exceptionally strong cryogenic community in Oxfordshire.

New state-of-the-art manufacturing facility for Eleet Cryogenics

Eleet Cryogenics, Bolivar OH, has expanded its manufacturing size and opened up new opportunities for the company’s development.

Fermilab director search committee members named

The next step has been taken in the search for the sixth director of Fermilab. On October 30 the Fermi Research Alliance LLC announced the names of the 16 members of the director search committee.

Study supports move toward common math standards

A new study analyzing the previous math standards of each state provides strong support for adoption of common standards, which US students desperately need to keep pace with their counterparts around the globe, a Michigan State University scholar argues.

Dark Energy Camera records first images

Scientists in the international Dark Energy Survey collaboration announced in September that the Dark Energy Camera, the product of eight years of planning and construction by scientists, engineers and technicians on three continents, has achieved first light.

HEP open access initiative at crucial juncture

Representatives from two dozen nations met on October 1 at CERN, the European particle physics laboratory, to officially launch the next phase of the SCOAP3 project, which aims to make all published literature in the field of high-energy physics available to readers for free.

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
