Danko van der Laan receives 2014 Boom Award

The Roger W. Boom Award is given bi-annually to a young professional under 40 years of age who shows promise for making significant contributions to the fields of cryogenic engineering and applied superconductivity. This year, the award was presented to Dr. Danko van der Laan during an awards ceremony on...

Tips for Success When Using an ADR Cryostat

Following up on his discussion in the Fall 2013 issue of Cold Facts on when an Adiabatic Demagnetization Refrigerator (ADR) cryostat is the right tool for the job, Charlie Danaher provides useful technical tips on how to effectively use an ADR.

Young Faces: The Next Generation in Cryogenics, Part I

In the Summer 2006 issue of Cold Facts, we debuted a feature story about outstanding young professionals who are active in the cryogenics industry. This year, we again asked the cryogenics community for the names of up-and-coming "young faces." Here is Part I of the third installment of Young Faces,...

BICEP2 and the Outer Edge of the Universe

The first BICEP (Background Imaging of Cosmic Extragalactic Polarization), BICEP1, observed with 49 spider-web bolometers for three years. BICEP2 carried 256 dual polarization transition-edge superconducting detectors of greatly increased sensitivity, and also observed for three years. Dr. Peter Mason reports here on the results of these two instruments and their...

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...

Specs and info on turbo expanders

I am a fourth year chemical engineering student doing a design project for the liquefaction of natural gas to DME and we are using a turbo expansion unit. I was wondering whether you would send me some specs and any additional information on turbo expanders that I could use as...

Colleges that offer cryogenic studies

Would you happen to know of any colleges in the US that offer cryogenics as a major? If not, should I major in something like biology or physics before, then branch off to the field of cryogenics? Any information that you could give me would be greatly appreciated, considering this...

Data on hardness of Indium?

Where can I find experimental data on the hardness of Indium, as a function of temperature, as well as any existing data on the thermal contact conductance of junctions containing Indium foil, also as a function of temperature?
