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...

Need a plastic for diffuser on the magnet end of a LHe fill siphon
I am trying to select a plastic to be used as a diffuser on the magnet end of a LHe fill siphon. Can you recommend anything that will hold up at LHe temps? I have seen some and they look like HDPE or Polypropylene but I am not sure.
Thermal conductivity orthotropic properties from 300K up to 500K
I am looking for the thermal conductivity orthotropic properties from 300K up to 500K (or even higher, if available). “Cryocomp” provides orthotropic data on G-10 (Fill, Warp, Normal) only up to 300K.
