The Kilo Is Dead. Long Live the Kilo!
An old artifact kept in a vault outside Paris is no longer the standard for the kilogram. Now, nature itself provides the definition.
Dark Energy Instrument’s Lenses See the Night Sky for the First Time
On April 1, the dome of the Mayall Telescope in Tucson AZ opened to the night sky, and starlight poured through the assembly of six large lenses that were carefully packaged and aligned for a new instrument that will launch later this year.
Advanced Superconducting Motor Experimental Demonstrator Addresses Environmental Concerns
Demaco Holland BV (CSA CSM) is lending its cryogenic expertise to the development of a rotor cryostat for the Advanced Supeconducting Motor Experimental Demonstrator, which will develop, build and test the first fully superconductive motor for aerospace applications.
Women in Cryogenics and Superconductivity 2019
CSA celebrates women in cryogenics and superconductivity. In this feature, six women in positions across the industry discuss current projects, how they entered the field and their thoughts on attracting more women to the profession.
NIST Explains the New Kelvin Definition
The definition of the kelvin (K)—the temperature unit of the International System of Units (SI), has been given a radically new definition. This redefinition was the result of 60 nations’ unanimous vote to revise the SI in November 2018.

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...

Data on thermal expansion down to 40K
For our cold mechanics, we use ball bearings from ADR from stainless steel which is AISI 440C, DIN X105CrMo17, W.Nr. 1.4125. Does anyone know the data of thermal expansion of this material down to 40 K?
Difference between radar and servo gauge for LNG tanks?
What is the difference between radar and servo gauge for LNG tanks? How do I understand the gauging system for LNG tanks and choose the best one?
Materials for "cryogenics in spacetech"?
I had to take a seminar in a national competition that is to be held in our country on the topic “cryogenics in spacetech.” For this, I need some materials related to it, and I thought to approach you for help. Can you suggest some relevant materials?
