SuperKEKB Commissioning Begins, Successful Storage of Beams in its Electron and Positron Rings Reported

After five years of large-scale upgrade work, Japan's High Energy Accelerator Research Organization (KEK) began test operations on SuperKEKB, an electron-positron colliding accelerator. SuperKEKB represents a major upgrade from the previous KEKB accelerator and is the culmination of years of construction that started in the second half of 2010. Commissioning...

James Webb “Telescope” Documentary Available to Stream

Discovery's "Telescope" documentary, highlighting the high-stakes mission to build NASA's James Webb Space Telescope, premiered on Feb. 20 and is now available for streaming on the TV channel's website. The Webb telescope, which is the scientific successor to—and 100 times more powerful than—Hubble, will peer back over 13.5 billion years...

Jefferson Lab Invites Public to Open House on April 30

The US Department of Energy’s Thomas Jefferson National Accelerator Facility, or Jefferson Lab, will hold an open house for the public on Saturday, April 30, from 9 a.m. to 3 p.m. It is an opportunity for people of all ages to spend the day exploring this world-class research facility. Visitors...

Fermilab Scientists Discover New Four-Flavor Particle

Scientists on the DZero collaboration at the US Department of Energy’s Fermilab have discovered a new particle—the latest member to be added to the exotic species of particle known as tetraquarks. Quarks are point-like particles that typically come in packages of two or three, the most familiar of which are...

Chart Ferox and PPS Win Contract for LNG Reloading Station in Lithuania

Chart Industries, Inc. announced on February 25 that its Czech subsidiary Chart Ferox and EPC consortium partner PPS Pipeline Systems Germany have been selected to provide an LNG reloading station for AB Klaipėdos nafta at the Port of Klaipeda, Lithuania. The project's aim is to develop Klaipeda as a Baltic...

New RF-SQUID Material Invisible to Microwave Radiation

University of Maryland (UMD) physicists and engineers from HYPRES (CSA CSM) have developed a new RF-SQUID cloaking material that can become transparent to microwave radiation with the flip of a switch. The new material could be used to design more efficient communications networks since many wireless communication devices rely on...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

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...

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
