Cryogenic CMOS Design for Quantum Chips on 22FDX

Semiwise in Glasgow has developed transistor SPICE models for cryogenic CMOS chip design and verification using the GlobalFoundries (GF) 22FDX  22nm fully depleted silicon-on-insulator (FD-SOI) process technology. The technology can be used for chips for quantum computers and also for data center processors with liquid nitrogen cooling. Semiwise used its patented...

Off-Grid Hydrogen Energy Maximizes Power of Steam

Dylan CHP LLC has researched, developed, and patented advanced steam generation technology, utilizing hydrogen to generate clean energy electricity. The Dylan System is based on extreme heat preservation (EHP), the heart of the Dylan patent that allows the Dylan Energy-Efficient System to achieve nameplate steam output while consuming only a...

Pancreatic Islet Cryopreservation Marks Breakthrough for Diabetes Cure

Engineering and medical researchers at the University of Minnesota Twin Cities and Mayo Clinic have developed a new process for successfully storing specialized pancreatic islet cells at very low temperatures and rewarming them with a laser and gold nanoparticles, enabling the potential for on-demand islet transplantation. The breakthrough discovery in...

Paragraf is Changing the Game with Cryogenic Hall Sensors

Due to limitations in size and power dissipation, many prevalent measurement methods are incompatible with low temperature applications. Hall effect sensors have emerged as the superior option because of their compact size and low-power requirement. Until now, conventional Hall sensors have themselves been limited by material capabilities and the quantum...

CryoEdge Solves an Ancient Problem with a Cutting-Edge Solution

Ever since the Stone Age, people have searched for the most effective ways to cut and shape materials for best use. This quest has most recently resulted in revolutionary breakthroughs and developments like lasers, plasma beams, and water jets as cutting instruments. Despite these advances, the overwhelming majority of cutting...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...
