How Lake Shore Cryotronics is Helping Reduce Helium Costs in The Lab

Lake Shore Cryotronics’ Director of Product Management for Cryogenic Systems Rachael Floyd shares how Lake Shore Cryotronics is helping reduce helium costs in the lab. Why is the availability of helium becoming a pressing concern for research labs, and what unique challenges does it pose? The high cost of helium is a big...

Cryo Legacy: Angela Krenn’s Reflections on Cryogenics and Space, a Trailblazer Revisited

In our annual “Women in Cryogenics and Superconductivity” feature, Cold Facts explores the profound contributions of outstanding women in the field. Drawing on its popularity, we wanted to have a candid conversation, reconnecting with a trailblazing woman in cryogenics, previously spotlighted as one of our “Women in Cryogenics.” In this...

New Glenn Completes Initial Cryogenic Testing at Launch Complex 36

Blue Origin continues to take big steps forward with its New Glenn orbital rocket as hardware rolls out to the launch pad, cryogenic testing begins, and the BE-4 engine gains a new test stand. The company still aims to launch New Glenn at least once in 2024. Over the past month,...

Maybell Quantum Announces $25 Million Series A Funding Led By Cerberus

Maybell Quantum (“Maybell”), the quantum infrastructure company, has closed a $25 million funding round led by an affiliate of Cerberus Capital Management, L.P. (“Cerberus”), a global leader in alternative investing. This investment marks the start of a pivotal chapter in Maybell’s development. With Cerberus’ financial backing and operational support, Maybell...

ISRO Achieves Big Milestone For Human Mission Gaganyaan’s Cryogenic Engine

The Indian Space Research Organisation (ISRO), the space agency of the government of India responsible for the country’s space research and exploration programs, has achieved a major milestone in the human rating of its CE20 cryogenic engine, which powers the cryogenic stage of the human-rated LVM3 launch vehicle for Gaganyaan human...

Surface Superconductivity Appears in Topological Materials

Researchers at the Leibniz Institute for Solid State and Materials Research at IFW Dresden, Germany, have found proof for surface superconductivity in a class of topological materials known as Weyl semimetals. Interestingly, the superconductivity, which comes from electrons confined in so-called Fermi arcs, is slightly different on the top and...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Cryogenic Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water 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?
