60 Years of DESY: From Hamburg Particle Accelerator to Global Research Center

For the past 60 years, fundamental research has been carried out at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg-Bahrenfeld. In those 60 years, DESY has become a world leader in accelerator technology, structure research, particle physics and astroparticle physics. DESY has developed pioneering technologies, which have been used by scientists from...

Jefferson Lab to be Major Partner in Brookhaven Electron Ion Collider Project

The Department of Energy (DOE) announced that it has taken the next step toward the construction of an Electron Ion Collider (EIC) in the United States. DOE announced that the collider will be sited at DOE’s Brookhaven National Laboratory in Upton NY. In addition, DOE’s Thomas Jefferson National Accelerator Facility...

FDA Expands Clearance of Cryoablation Technology for Kidney, Liver, Head and Neck Tumors

The US Food and Drug Administration has expanded the clearance of a cryoablation technology platform for the treatment of cancerous and benign tumors of the kidney, liver, ear, nose or throat, according to a press release from the product’s manufacturer.

The Pocket-Sized Particle Accelerator

The accelerator-on-a-chip is just a prototype, but its design and fabrication techniques can be scaled up to deliver particle beams accelerated enough to perform cutting-edge experiments that don’t require the power of a massive accelerator. By placing these chips in a series, researchers from SLAC National Laboratory and Stanford University...

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.

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 Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

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?
