How Helium Can Be Solid And Perfect Liquid At Same Time, Now Explained By Computer-assisted Physics

At very low temperatures, helium can be solid and a perfect liquid at the same time. Theoreticians, though, have incorrectly explained the phenomenon for a long time. Computer simulations at ETH Zurich have shown that only impurities can make this effect possible.

Large Hadron Collider to get helium leak warning system after breakdown

Official report says one tonne of liquid helium escaped through faulty connection, causing damage costing £20m to 53 magnets

LHC: The Return of the Unquenchables

Sneak has decided to return to the subject of CERN's Large Hadron Collider, now that the follow up report about what went wrong on 19 September 2008 has been released. The report goes into a fair amount of technical detail about the incident, but the upshot is - it was a very large 'quench', known in the trade as a 'catastrophic quench', where helium expands explosively due to the previously superconducting wires becoming non-superconducting wires, heating up and boiling off the helium.

Accident: Helium leak halts CERN facility tests; root cause

At CERN, during commissioning testing, an arc flash punctures a cryogenic tank, damages steering and focusing magnets, and contaminates beamline. Could this CERN accident have been prevented?

Large Hadron Collider to Get Helium Leak Warning System

The Large Hadron Collider (LHC) is to have an early-warning system installed to guard against a repeat of the catastrophic fault that caused the world’s largest atom-smasher to break down nine days after it was switched on in September.

First LHC proton collisions postponed further

Large Hadron Collider needs until next summer to recover from a helium leak that shut the new atom smasher down in September

Balloon priest wins Darwin Award for stupidity

A daredevil Catholic priest who was killed after floating out to sea suspended by 1,000 helium-filled party balloons has been honoured for his idiocy.

Theory ties radio signal to universe's first stars

The first stars ever to grace the cosmos with light were brutish monsters, so the story believed by most astronomers goes, lumbering clouds of hydrogen and helium hundreds of times more massive than the Sun. They lived fast and bright and died hard, exploding or collapsing into massive black holes less than a billion years after the Big Bang, never to be seen again.

Photos of the Damage To the Large Hadron Collider

holy_calamity writes "CERN have released images of the damage done to the world's most powerful machine, the Large Hadron Collider, when an electrical fault caused a helium leak. New Scientist has posted them, along with explanations of what you can see. The sudden burst of gas shifted some of the huge superconducting magnets by half a meter, causing at least $21 million in damage."

Photos: The damage that halted the LHC

On Friday, the European Center for Nuclear Research (CERN) released photos of damage to the Large Hadron Collider, CERN's flagship particle accelerator. The particle accelerator was damaged by a liquid helium leak in September, nine days into an experiment to test fundamental theories of physics by colliding beams of protons inside a 17-mile ring.

First Images Emerge of Damage to the LHC, Replacements Arrive

On September 19th, CERN announced that the Large Hadron Collider had suffered a major incident, known as a "quench". An electrical short between two of the superconducting magnets had kick-started a helium coolant leak inside the tunnels housing the accelerator ring. The quench caused the magnets to rapidly heat up, severely damaging them. The violent release of coolant ripped equipment from their concrete anchors, ensuring a huge repair operation would need to be carried out. However, it was a while before engineers were able to access the damage and the news wasn't good: The LHC would be out of commission until the spring of 2009 at the earliest. That was such a sad day.

Teddy Bears Go To Space

I don't think this is what Iran has in mind about launching animals into space, but … you never know. Four teddy bears voyaged to the edge of space on Monday, December 1st via high altitude helium balloon. This was done as an experiment by a student organization at Cambridge University in England, along with a science club and community college. The bears were lifted to 30,085 meters above sea level, and the goal of the experiment was to determine which materials provided the best insulation against the -53 ° C temperatures experienced during the journey. Each of the bears wore a different space suit designed by 11-13 year-olds who were took part in the experiment. But the main goal of the endeavor was to give young students the opportunity to try their hand at a real mission in sending objects into space.

Website: Fast Dark Matter Explains Cosmic Web, Accelerating Cosmos, Inflation, UHECRs, Big Bang

LOS ALTOS HILLS, Calif., Dec. 8 (AScribe Newswire) -- Scientists at UC Santa Cruz claim that about 85 percent of the mass of the universe is Cold Dark Matter (CDM), comprised of cold, uncharged, weakly interacting massive particles (WIMPs) that contain no nuclei or atoms of hydrogen, helium, oxygen, nitrogen or any other atoms/nuclei. Such extraordinary claims require extraordinary evidence to be convincing, yet UC Santa Cruz has not provided any astronomical evidence after 24 years of research.

Handheld Alloy Analyser

Faster testing speeds and improved analytical performance are providedby a new detector for the Niton XLT3t alloy analysers. Measurement times are 10 times quicker than with conventional detectors, while accuracy is up to three times better than conventional silicon PIN detectors. Another advance is that the light elements aluminium, silicon, phosphorus and sulphur can be detected without the need for helium or vacuum purging. The detector uses new geometrically optimised large area drift detector (GOLDD) technology to deliver laboratory quality performance for these x-ray fluorescence (XRF) instruments. All the Niton XL3series analysers are supplied with Niton Data Transfer software, a suite of data management utilities.
