Undergrads Construct Cryogenic Star-Tracking Instrument

A team of undergraduates from the Rochester Institute of Technology (RIT) will soon deploy its Cryogenic Star Tracking Attitude Regulation System, a telescope and camera based “compass” for rockets that will orient the payload based on the images of stars. CSTARS uses a new kind of detector technology and will...

19th International Cryocooler Conference

A group of 180 researchers and engineers from 12 countries gathered in San Diego June 20-23 for the 19th International Cryocooler Conference (ICC19), coordinated by the NASA Jet Propulsion Laboratory (JPL) and held at the Town and Country Resort and Convention Center. The conference included a combination of 80 oral...

LIGO Collaboration Prepares Cryogenic Update

In the past year, the Laser Interferometer Gravitational-wave Observatory (LIGO) has twice observed gravitational waves from the merger of black holes in deep space. Thermal noise, however, limits how small a motion the system can detect. In order to address this issue, and thus take the next big step in...

SCW Student Scholarship Established

CSA has established the T.H.K. Frederking Space Cryogenics Workshop (SCW) Student Scholarship, an award honoring our first CSA Fellow, Dr. Traugott Frederking, who generously sponsored selected students to attend SCW to help develop their technical maturity by exposing them to current leaders and emerging developments in the field.

Experts Engineer New Cryostat Design Volume

The proper design of cryostats requires knowledge of many disciplines including: cryogenic properties of materials, heat transfer and thermal insulation, instrumentation, safety, structures and seals. One of the best ways to learn about cryostat design is to study the design choices and resulting performance of previous designs. This book provides...

Technifab Restructures, Announces Three Divisions

Technifab Products, Inc. (CSA CSM) has announced organizational changes, segmenting its business into three distinct divisions—Technifab Cryogenics, Technifab CNC Manufacturing and Technifab Cryodewars.

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...
