ITER Takes First Steps Toward Cryoplant Commissioning

Every week since the beginning of November, a tube trailer filled with approximately 4,600 cubic meters (750 kg) of compressed gaseous helium delivers its load to the ITER cryoplant in the south of France. At a later stage, the deliveries will become more massive, as helium is delivered in liquid...

Jefferson Lab Accelerator Gets a Fresh Pair of Eyes

A newly invented detector is allowing physicists at the US Department of Energy’s Thomas Jefferson National Accelerator Facility (CSA CSM) to “see” neutrons like never before. Fresh insight from these devices has improved operation of the lab’s powerful electron accelerator, which is used in nuclear physics studies of the atom’s...

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.

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...

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...
