Lake Shore Unveils New Probe Arm

Lake Shore Cryotronics, Inc. (CSA CSM) is now offering for pre-order a unique terahertz-frequency probe arm option for its CPX, CPX-VF, CRX-4K and CRX-VF cryogenic probe stations. The arm enables precise probing and measurement of millimeter-wave devices at 75 to 110 GHz (WR10 band) or 140 to 220 GHz (WR5.1...

New Multi-Layer Insulation Hybrid is Supacool

Technical Fibre Products has launched of a new variant of its Supacool range of lightweight cryogenic tissues. It features a lightweight microfine glass spacer tissue co-wound with aluminum foil, forming the basis of multi-layer insulation or super insulation that can be inserted between the inner and outer walls of a...

Dark Matter Unseen in Hitomi’s Glimpse at Perseus Cluster

A large X-ray signal previously seen emanating from the Perseus galaxy cluster did not appear in the final data sent by the Hitomi spacecraft, casting a shadow over speculation that the anomalously bright signal might have come from dark matter.

Navy Buoys Cryogenic Radio Frequency Research

The US Navy Space and Naval Warfare Systems Center Pacific recently awarded contracts that shore up its efforts to develop new cryogenic radio systems. The award covers a broad range of R&D, according to the bid proposal, including signal detection, conditioning, conversion, processing and storage.

Physicists Reach 91 K with Laser Cooling

A group of scientists at the University of New Mexico’s Department of Physics and Astronomy are using lasers to advance optical refrigeration, a technique that reaches cryogenic temperatures without any moving parts.

Chicago Hosts World’s Largest High-Energy Physics Conference

More than 1,300 physicists from around the world will converge in Chicago for the biennial International Conference on High Energy Physics (ICHEP) in August to share new research results, announce new projects and talk about the most intriguing mysteries of the universe. The conference will meet August 3-10 at Chicago's...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Refrigeration capacity at 4.5 K for higher temp cryo systems

I would like to know how to calculate the equivalent refrigeration capacity at 4.5 K of a cryogenic system operating at higher temperature.

Need help with calculating flow rate

I have to maintain a certain mass (some tons) at 100 K by circulating in it GHe (through apposite channels). How can I calculate the flow rate needed? I suppose that the delta T (T inlet and T outlet) and the heat load on the mass are necessary. Knowing the...
