A Brief Report on the First Cooldown of SPIRAL2

Over the last 10 years, a multidisciplinary team from institutes around the world has worked to design, fabricate and assemble SPIRAL2, a new generation heavy ion superconducting linear accelerator (LINAC) at the Grand Accélérateur National d’Ions Lourds (GANIL) facility in Caen, France.

SSRL X-ray Uncovers Hidden Ancient Text

More than 1,600 scientists from all over the world use the Stanford Synchrotron Radiation Lightsourse (SSRL) at SLAC National Accelerator Laboratory each year for research that spurs advances in medicine, energy production, environmental cleanup, nanotechnology and new materials. And now, a multidisciplinary team has used the machine’s acceleratordriven X-rays to...

Young Professionals 2018: The Next Generation in Cryogenics Part 1

Young Professionals introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields. Debuted in the Summer 2006 issue, the feature has presented many young persons whom we are proud to see...

Experiment Seeks Neutrinoless Double-beta Decay

Collaborators of the Majorana Demonstrator, an experiment led by Oak Ridge National Laboratory, have shown they can shield a sensitive, scalable 44-kilogram germanium detector array from background radioactivity.

Fertility Clinic Wireless Temperature Monitoring Protects the Irreplaceable

The recent back-to-back failures at two US fertility clinics are beyond stunning and have resulted in the loss of thousands of frozen human embryos. The breakdowns, which occurred in separate clinics in Cleveland and San Francisco, were apparently unrelated but nevertheless expose both the wonder and the fragility of this...

Boeing and Rolls Royce Back Self-creating Liquid Oxygen Engine

UK-based Reaction Engines Limited REL has raised an additional £26.5 million in funding from Boeing HorizonX Ventures and Rolls Royce for its SABRE engine project. Researchers plan to begin testing the engine in 2020. Engineers designed it to produce its own liquid oxygen by cooling air entering the engine during...

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...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?
