Report on ICCR2013 in Hangzhou, China
Held at Zhejiang University, Hangzhou, China, April 6-9, the 5th International Conference on Cryogenics and Refrigeration (ICCR2013) attracted more than 330 participants from 17 nations and areas, with 220 papers presented.
Inside Fermilab’s New Strand and Cable R&D Lab
The mission of the Superconducting Strand and Cable R&D program is to understand and improve scientific and engineering aspects of superconducting strands and cables for accelerator magnets, including dipoles, quadrupoles and solenoids. Since 1998, the lab has also served as the ideal experimental environment for 30 graduate students in physics...
Cold Facts Tours NHMFL, ASC and CAPS
In February of this year, CSA was invited to the National High Magnetic Field Laboratory (CSA CSM) at Florida State University to tour its facilities and meet key personnel at the forefront of cryogenic and superconducting technology at the lab. On our tour we were taken behind the scenes to...
Does Cryogenic Electronics Have a Role in Electric Power?
Electric power systems—whether for electric utilities or on ships, airplanes or automobiles—require electronic power circuitry to change voltage levels and to convert between DC and AC, as well as for controlling power delivery. The use of superconductivity and cryogenics for motors, generators, energy storage and power distribution leads naturally to...

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...
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?
