TRIUMF and KEK strengthen partnership to advance physics research

At a signing ceremony hosted on December 4 at the Canadian Embassy in Japan, the heads of Canada’s TRIUMF and Japan’s KEK signed a new partnership agreement to enhance research collaborations between the two centers and promote joint projects in the areas of subatomic physics, accelerator science and materials science.

Researchers developing shoebox-sized particle accelerator

The Gordon and Betty Moore Foundation in November awarded $13.5 million to Stanford University for an international effort, including key contributions from the Department of Energy’s SLAC National Accelerator Laboratory, to build a working particle accelerator the size of a shoebox. The technique, based on a technology known as “accelerator...

Innovation boosts study of fragile biological samples at SLAC’s LCLS

Researchers at the Department of Energy's SLAC National Accelerator Laboratory have found a simple new way to study very delicate biological samples—like proteins at work in photosynthesis and components of protein-making machines called ribosomes—at the atomic scale using SLAC's Linac Coherent Light Source (LCLS) X-ray laser.

SCOAP3 outlines its impact on open access publishing

The SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics) executive committee on November 18 held an online forum to discuss the partnership’s impact since its founding in nearly two years ago. SCOAP3 members include libraries, publishers, funding agencies and research centers in more than 40 countries with CERN...

Worthington acquires Taylor Wharton’s CryoScience business

Worthington Industries, Inc., announced its cryogenics business in the pressure cylinders segment is purchasing the assets of the global CryoScience business of Taylor Wharton Cryogenics, including a manufacturing facility in Theodore AL. Worthington will also acquire certain other intellectual property and manufacturing assets of Taylor Wharton focused on the cryogenic...

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...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

Seeking recommendations for commercial sensors

I would like to measure vibrations in small LHe cryostats. Could anybody recommend commercial sensors which would be suitable for the purpose? I am interested in the frequency range between 1Hz and a couple of KHz, with particular attention to the low frequency side.

Estimating cost of carbon steel, pure helium storage tanks

In order to perform an indicative cost assessment of our helium cryogenic plant (still in the design phase), I need an estimation of the cost of carbon steel room temperature pure helium storage tanks. The storage pressure is 20 bar. Can anyone give me suggestions about how to estimate the...

Supplier of pressure sensor that works down to 4.2 K

In an actual experiment we would like to measure the static pressure in a cryostat in the range between one and four bar. Therefore we are looking for some (more or less) cheap pressure sensors that work in liquid helium in the pressure range up to five bar. Unfortunately all...

Looking for reference/textbook suggestions

Can you suggest some reference textbooks for practical thermodynamics applications in cryogenic fields? I need textbooks with cryogenics calculations and examples, dimensioning procedures, second principle applications in cryogenics, heat load calculations, cryogenic pump application, etc. Do such books exist? Does any similar source of information exist?
