Pelican Wire Designs for Cryogenic and Extreme Energy Systems

As renewable energy, electrification and advanced research technologies continue to expand, the demands placed on wire and cable systems are evolving just as rapidly. Higher power densities, tighter system integration and increasingly extreme operating environments are pushing manufacturers beyond traditional commodity wire solutions. Caleb Lemmons, Business Development Manager at Pelican...

From Cryogenic to Red-Hot: Optical temperature sensing from 77 K to 873 K

by University of Innsbruck An international collaboration involving researchers from the University of Innsbruck has developed a novel luminescent material that enables particularly robust and precise optical temperature sensing across an exceptionally broad temperature range. Optical luminescence thermometry has been gaining increasing attention, as it allows contactless temperature measurement even under...
Researchers at QuTech, working on a Fujitsu-funded project, have developed the first cryogenic control chip able to directly control both electron and nuclear spins in diamond-based qubits.

Scalable Diamond Quantum Computing with Cryogenic Chip Integration

NV centers are among the most promising qubit platforms, combining fast electron-spin control with exceptionally stable nuclear-spin memories. However, until now, these systems have depended on room-temperature electronics connected by long cables to the cryogenic environment: a setup that considerably hinders scalability and reliability. The new cryo-CMOS controller solves this...

What Happens When Industry Demands the Impossible? Superconductors Step In

Energy transformation is not simply a fuel switch – it’s a redesign of the systems that underpin economic growth and national energy security. Electricity demand is rising sharply, driven by the electrification of end uses and the rising demand from data centres and AI. At the same time, power systems...

Booster 19 Rolls out to Masseys for Cryogenic Proof Testing

written by Ryan Weber  Following Booster 18’s failure during a pressure test, SpaceX went ahead and set a new record for stacking a booster in the Starship Program, to try and get Block 3 and the program at large back on track. And this weekend, crews rolled Booster 19 out to...

Provaris Delivers on First Phase LCO2 Tank Engineering and Design

By Dominic Ellison  Australian hydrogen and carbon dioxide storage and transport firm Provaris Energy has completed the phase-one delivery of an LCO2 tank front end engineering and design (FEED) program. The programme included detailed engineering and material and weld testing of a 25,000 cbm LCO2 low-pressure tank and class approval with...

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

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...
