H2 Storage System Successfully Scaled up

Since September 2023, AMBARtec has been testing its 7.5 kg H2 storage system in full operation with hydrogen. The aim was also to optimise the plant control and find the best system configuration in terms of energy balance. Maximum energy efficiency: AMBARtec’s storage system + SOECThe energy balance analysis shows...

These awards are part of the CEC’s ongoing efforts to encourage the next generation of engineers and scientists in the field...

Beckman Institute Labs Bridge Advanced Imaging and Alzheimer’s Research

The Beckman Institute for Advanced Science and Technology at the University of Illinois Urbana-Champaign has embarked on a life-changing research project to advance the early detection and diagnosis of Alzheimer’s disease. With the support of a $3 million grant from the US National Institute on Aging of the National Institutes...

Bluefors Lab Offers Cryo Measurements, a Low Risk Model for Experiments

Quantum technology continues to develop at a rapid pace, and the need for access to cryogenic cooling systems for quantum research has never been greater. While established institutions have an increasing number of options to choose from, startups and smaller institutions still face considerable challenges, not least of which are...

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...

Seeking recommendations for commercial sensors

I would like to measure vibrations in small LHe cryostats. Could anybody recommend commercial sensors which would be suitable for the purpose? I am interested in the frequency range between 1Hz and a couple of KHz, with particular attention to the low frequency side.

Estimating cost of carbon steel, pure helium storage tanks

In order to perform an indicative cost assessment of our helium cryogenic plant (still in the design phase), I need an estimation of the cost of carbon steel room temperature pure helium storage tanks. The storage pressure is 20 bar. Can anyone give me suggestions about how to estimate the...

Supplier of pressure sensor that works down to 4.2 K

In an actual experiment we would like to measure the static pressure in a cryostat in the range between one and four bar. Therefore we are looking for some (more or less) cheap pressure sensors that work in liquid helium in the pressure range up to five bar. Unfortunately all...

Looking for reference/textbook suggestions

Can you suggest some reference textbooks for practical thermodynamics applications in cryogenic fields? I need textbooks with cryogenics calculations and examples, dimensioning procedures, second principle applications in cryogenics, heat load calculations, cryogenic pump application, etc. Do such books exist? Does any similar source of information exist?
