QuinStar Completes Contribution to NASA Mission

QuinStar (CSA CSM) has successfully completed a 28-month program with the Jet Propulsion Laboratory that developed flight hardware for the NASA-ISRO (Indian Space Research Organization) Synthetic Aperture Radar (NISAR) mission. QuinStar’s deliverables included Ka-band solid-state power amplifiers—an enabling element of the communication payload for the high speed, space-to-earth datalink.

Italian Energy Company Doubles Blend of Hydrogen

Italian energy infrastructure company Snam has doubled the volume of hydrogen it is blending with natural gas in the transmission network of southern Contursi Terme, Salerno, Italy, in a new experiment that would enable the reduction of the region’s carbon dioxide emissions by five million tons.

Light Powers World’s Fastest Spinning Object

A dumbbell-shaped nanoparticle powered just by the force and torque of light has become the world's fastest-spinning object. Scientists at Purdue University created the object, which revolves at 300 billion revolutions per minute. Or, put another way, half a million times faster than a dentist's drill. In addition, the silica...

World’s First Hydrogen-Powered Superyacht is Here and It Is a Beauty

The world's first hydrogen-powered superyacht was unveiled last week at the Monaco Yacht Show and it made quite an impression. The model of the 367-foot yacht was the pinnacle of luxury and sophistication. The miniature model was presented by a Dutch firm called Sinot Yacht & Architecture Design. The ship,...

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...

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...
