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...

Latest in Defining Cryogenics

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

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?
