US House passes bill to head off massive helium shortage

On April 26, the US House of Representatives passed a bill by a vote of 394 to 1 that would head off a critical shortage of helium that is sure to strike in October if Congress does nothing. That news should come as a relief to the thousands of scientists...

Herschel closes its eyes on the universe

ESA’s Herschel space observatory has exhausted its supply of liquid helium coolant, ending more than three years of pioneering observations of the cool Universe.

Two new senior staff scientists appointed at SLAC

The leader of SLAC's involvement in the Cryogenic Dark Matter Search and an instrument scientist with the Linac Coherent Light Source X-ray laser have been appointed senior staff scientists at SLAC.

Cryogenic Dark Matter Search adds new intrigue with the latest result

Physicists operating an experiment located half a mile underground in Minnesota reported that they have found possible hints of dark-matter particles. The Cryogenic Dark Matter Search experiment has detected three events with the characteristics expected of dark matter particles, MIT graduate student Kevin McCarthy reported at the American Physical Society...

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...

What is the temperature range of cryogenics?

Could you please tell me what is the temperature range of cryogenics? In other words, is -100°F considered cryogenic, or does it start lower? Could I expect to see some extended life in D2 stamping dies? What would the recipe be to achieve the desired results using cryogenics?
