The creature could have been a stoat which is similar to a weasel.
Although under normal circumstances a weasel would be weasily recognised and a stoat would be stoatally different, a charred one might be a bit trickier to identify.
I take it then you have a culinary interest in one but not the other by the look of that tongue of yours, with an anxiety to know which.
Superconducting wires to save energy The main line, made of copper, has high energy yields, but it loses some energy on its journey to the internal magnet feeders through electrical resistance, and when it is cooled to the temperatures needed in the LHC. To tackle this energy-loss problem, superconducting wires made of niobium-titanium (NbTi) are used on the LHC to connect electromagnets to their power supply. The wires can conduct 100 times the current of traditional copper wire because when cooled to close to absolute zero they offer no resistance to electricity. This greatly cuts down on the energy lost as electricity travels down the wire. To reach a superconducting state, LHC magnets are maintained at 1.9 K (-271.3°C) – temperatures colder than outer space – by a closed liquid-helium circuit. The copper wire on the left is 11 centimetres high, 8 cm wide and 28 cm long. It can conduct a current of 12,500 amps at room temperature. When cooled to 1.9 K, the niobium-titanium coil on the right enters a superconducting state and can conduct the same current (Image: CERN) As electricity courses from its source to the LHC, it passes through a temperature gradient. Water cools the copper cables to ease the conversion from room temperature to the cryogenic atmosphere maintained around the accelerator. Currently, the main cost of superconductivity is the cooling process. Whatever energy is earned through the use of superconducting wires is lost in the energy needed to cool the wires. But CERN researchers are working on a way to use superconducting cables for the entire journey from source to magnet, which would lower the energy required to cool the wires.
The Large Hadron Collider (LHC) was halted "following technical issues, including a power cut due to the passage of a weasel on a high voltage electrical transformer," CERN spokesman Arnaud Marsollier (said)
A team assessed the situation over the weekend and found no indication of damage inside the transformer. Repairs to the connections are hoped to be completed by the end of the week, as the LHC continues to prepare for the 2016 physics run.
Scientists had been gearing up to resume experiments at the LHC this week, but the plans were delayed after a weasel wandered onto a high-voltage electrical transformer last Friday, causing a short-circuit.
CERN told AFP that experiments were now expected to get underway next week.
The unexpected excess pair of photons spotted last year could be a larger cousin of the Higgs, according to one theory.
After the Higgs discovery, the LHC underwent a two-year upgrade, reopening last year with double energy levels which will vastly expand the potential for groundbreaking discoveries.
The LHC ran for six months last year at the new energy level of 13 teraelectronvolts (TeV), but since the machine was just getting started again, it was not pushed to create the maximum number of collisions.
Once it gets started again, the machine at its peak should see two beams each containing around 273,600 billion protons shoot through the massive collider in opposite directions, slamming into each other with a joint energy level of 13 TeV to produce two billion collisions a second.
The LHC is running extremely well,” says CERN Director for Accelerators and Technology, Frédérick Bordry. “We now have an ambitious goal for 2016, as we plan to deliver around six times more data than in 2015.”
“The restart of the LHC always brings with it great emotion,” says Fabiola Gianotti, CERN Director General. “With the 2016 data, the experiments will be able to perform improved measurements of the Higgs boson and other known particles and phenomena, and look for new physics with an increased discovery potential.”
During the first phase of Run 2 in 2015, operators mastered steering the accelerator at this new higher energy [13 Tev] by gradually increasing the intensity of the beams.
Beams are made of “trains” of bunches, each containing around 100 billion protons, moving at almost the speed of light around the 27-kilometre ring of the LHC. These bunch trains circulate in opposite directions and cross each other at the centre of experiments. Last year, operators increased the number of proton bunches up to 2244 per beam, spaced at intervals of 25 nanoseconds.
The four largest LHC experimental collaborations, ALICE, ATLAS, CMS and LHCb, now start to collect and analyse the 2016 data. Their broad physics programme will be complemented by the measurements of three smaller experiments – TOTEM, LHCf and MoEDAL – which focus with enhanced sensitivity on specific features of proton collisions.
