OPERA Presents Its Final Results on Neutrino Oscillations

In a paper published in the journal Physical Review Letters, the OPERA collaboration reports the observation of a total of 10 muon to tau-neutrino conversion events, demonstrating unambiguously that muon neutrinos oscillate into tau neutrinos on their way from CERN, where muon neutrinos were produced, to OPERA at the Gran...

NASA’s Cold Atom Lab Launches, Coldest Spot in Universe Now on ISS

NASA's Cold Atom Lab (CAL) facility was included in the cargo that launched to the International Space Station on the Orbital ATK CRS-9 mission. CAL produces clouds of atoms that are ten billion times colder than deep space, using lasers and magnetic forces to freeze the atoms until they are...

Canadian Researchers Working on Novel MRI for ISS

The Canadian Space Agency has awarded a research team at the University of Saskatchewan a contract to design and engineer an ankle-sized MRI device for the International Space Station. The device, according to the team, will ultimately monitor the bone health of astronauts during prolonged space trips, where weightless conditions...

Jlab Research Shows Protons under More Pressure Than Neutron Stars

Scientists at the Thomas Jefferson National Accelerator Facility (CSA CSM) recorded the first measurement of pressure distribution inside a proton and reported in journal Nature that inside every proton in every atom in the universe is a pressure cooker environment that surpasses the atom-crushing heart of a neutron star.

Brooks Expands Freezer Line to Support Cryobags

Brooks Life Sciences, a division of Brooks Automation (CSA CSM), announced the launch of its BioStore III Cryo automated freezer for 250ml cryobags at the International Society for Cellular Therapy Conference (ICCT 2018) in Montreal. The latest version of its freezer brings simple, automated management for 250mL cryobags to the...

UK Researchers Form First National Biobank

The UK’s National History Museum announced a new initiative to collect and preserve the DNA of thousands of animals at a biobank called CryoArks. The collection of zoological tissue will provide a central hub for researchers across the UK, according to the museum, providing access to cells and DNA from...

Mixed Refrigerant Cycles

Most cryogenic refrigeration systems, both large scale systems and cryocoolers, use helium as a working fluid. There are a number of advantages to helium, not the least of which is that helium remains a fluid down to the lowest achievable temperatures. In order to freeze helium, pressures of over 20...

Fountain Pumps and He II Phase Separators

Helium II (He II), the second liquid phase of the 4He isotope described in this column in Cold Facts Spring 2010 (http://2csa.us/he2), can be modeled as consisting of two interpenetrating fluids. One, the superfluid component, has zero viscosity and entropy and the other, the normal fluid component, has nonzero viscosity...

Turboexpanders

A vital technology in the refrigerators and liquefiers described in Cold Facts Volume 31 Number 3 is that of turboexpanders. These devices are rotating machines in which the process fluid (e.g., helium) does work against the turboexpander while moving from high pressure to a lower pressure and thus is cooled....

Air Separation and Liquefaction

by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. You are encouraged to read Cryo Central’s History...

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...
