Goodwill Cryogenics Releases Cryo-Founders Calendar

This month, India’s Goodwill Cryogenics produced and shipped the first-ever “Cryo-Founders Calendar.” Dr. Vinod Chopra, Goodwill’s founder, designed it as a tribute to 12 legends of cryogenics. Each month features a different leader in the field of cryogenics with a short bio and list of notable achievements. Included in this...

Pakistan’s First Private LNG Shipment Expected by December

Pakistan’s first private LNG shipment, comprising approximately 130,000 cubic meters, is scheduled to arrive at Karachi by the end of November, according to Ghiyas Abdullah Paracha, chief executive officer of Universal Gas Distribution Company. He stated that he appreciated the government’s approval for the private sector to import LNG and...

LCWS Participants Publish ‘Sendai Statement’ in Support of the International Linear Collider

Scientists gathering in Sendai, Japan, for a scientific conference about a possible future particle physics project to lead the next generation of research following the Large Hadron Collider at CERN in Geneva reaffirmed their commitment to engage in the construction and scientific exploitation of the International Linear Collider as a...

New Payload Fairing from RUAG Space Enables Quieter Journey to Space

RUAG Space (CSA CSM) has successfully developed and tested a new, low shock jettison system funded by the Future Launchers Preparatory Program (FLPP) of the European Space Agency (ESA). The program develops technologies for future European launch vehicles and upgrades of existing launch vehicles. This system enables a quieter and...

LN2 Freezing of Live Bacteria in Dairy Products Boosts Productivity, Lowers Costs

GEA, an Australian electrical component company, has now launched a nitrogen freezing pilot plant for bacteria which takes a novel approach: freezing the bacteria in droplets using a liquid nitrogen bath outside the freeze dryer, then drying the pellets via the normal procedure. By freezing bacteria into pellets before drying,...

Thales Cryogenics, Eindhoven Receives NASA Awards

NASA has awarded the cryogenics department at Thales, Eindhoven two recognitions at its 2019 Honors ceremony held at the Jet Propulsion Laboratory in Pasadena the week of November 11. Both were awarded for Thales’ contribution to the success of the ongoing ECOSTRESS mission. The group received the NASA Group Achievement...

Joule-Thomson Effect

The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under...

Current Leads

One of the challenges of using superconducting magnets is the connection of the magnet to a room temperature power supply. This is accomplished via current leads. The trick is that current leads should ideally have a low heat leak, since they connect room temperature to cryogenic temperature, while at the...

Multilayer Insulation

Multilayer insulation (also referred to as superinsulation) is a key component in the reduction of heat leak to cryogenic systems due to thermal radiation. MLI consists of a series of uncooled reflective surfaces placed in the vacuum space between two surfaces, one warmer than the other. Generally speaking, for ideal...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

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?
