Over a Year Later, Construction Continues to Progress on PIP-II Cryoplant Building

Ground broke on the PIP-II Cryogenic Plant Building in July 2020 at Fermilab (CSA CSM) and construction began that August. This project is integral to PIP-II’s success, as the building will house cryogenic equipment that will cool the accelerator and mechanical, as well as electric utilities for the linac complex.

Valcor Release Cryogenic Launch Vehicle Valves White Paper

One of the biggest challenges to designing valves for launch vehicle applications, particularly for the upper stages, is meeting flow requirements within tight envelope and weight specifications. Valcor, a company that specializes in the design and manufacture of pilot-operated valves capable of achieving high flows in a compact and lightweight...

Startup Displays India’s First Privately Developed, 3D-Printed Cryogenic Engine

Hyderabad-based startup Skyroot Aerospace has successfully demonstrated the country’s first privately developed cryogenic rocket engine named Dhawan-1 after eminent rocket scientist Satish Dhawan. The company will use the engine as the upper stage of its Vikram-2 launch vehicle.

Plug Power Selected by Fertiglobe’s Green Hydrogen Consortium to Deliver 100mw Electrolyzer for Green Ammonia

On November 24, Plug Power Inc., a leading provider of turnkey hydrogen solutions for the global green hydrogen market, announced it has been selected by Fertiglobe the strategic partnership between OCI NV and the Abu Dhabi National Oil Company (ADNOC) and Scatec ASA, the Sovereign Fund of Egypt and Orascom...

International Linear Collider: Thinking Outside the Tunnel

If you think that the International Linear Collider (ILC) is going to be a one-trick pony for studying the Higgs boson, think again. In fact, think research for self-driving cars, think dark matter with axions or dark photons, customs X-rays in a tunnel, photon beams to create tetraquarks and pentaquarks,...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
