LHC Scientists face major setback

1st April 2014. The LHC is currently in shutdown in preparation for the next physics run in 2015. However the record breaking accelerator is danger is falling far behind schedule as the engineers struggle with technical difficulties 100m below ground level.

The LHC tunnels house the 27km long particle accelerator in carefully controlled conditions. When the beams circulate they must be kept colder than anywhere else in the solar system, and with a vacuum more empty the voids of outer space. Any disruption to the cryogenic cooling systems or the vacuum systems can place serious strain on the operations timetable, and engineers have found signs of severe damage.

Scientists patrol the LHC, inspecting the damaged areas.

The first indications of problems were identified coming from Sector 7 between areas F and H. Cryogenics expert, Francis Urquhart said “My team noticed dents in the service pipes about 50cm from the floor. There was also a deposit of white fibrous foreign matter on some of the cable trays.” The pipes were replaced, but the damage returned the following day, and small black aromatic samples were found piled on the floor. These were sent for analysis and after chemical tests confirmed that they contained no liquid Helium, and that radiometry found they posed no ionisation risk, they were finally identified as Ovis aries depositions.

Ovis aries are found throughout the CERN site, so on-site contamination could not be ruled out. It is currently thought that the specimens entered the Super Proton Synchrotron (SPS) accelerator and proceeded from the SPS to the LHC, leaving deposits as they went. The expert in charge, Gabriella Oak, could not be reached for comment, but is said to be left feeling “rather sheepish”.

Elsewhere on the ring there was another breach of the security protocols as several specimens of Bovinae were found in the ring. The Bovinae are common in Switzerland and it due to their size, must have entered via one of the service elevators. All access points and elevators at the LHC are carefully controlled using biometry and retinal scans, making unauthorised entry virtually impossible. Upon being asked whether the Bovinae had been seen scanning their retinae at the security checkpoints, Francis Urquhart replied “You might very well think that. I could not possibly comment.” While evidence of such actions cannot be found CCTV footage, there have been signs of chewed cud found on the floor, and Bovinae deposits, which are significantly larger than the Ovis deposits, owing to the difference in size.

The retinal scans at the LHC are designed exclusively for human use. A search of the biometric record database show at least one individual (R Wiggum) with unusual retinae, affiliated to “Bovine University”.

It is not known exactly how much fauna is currently in the LHC tunnels, although it is thought to be at least 25 different specimens. They can be identified by the bells they carry around their necks, which can sound like klaxons when they charge. Until the fauna have been cleared, essential repair work is extremely difficult. “I was repairing some damage caused by a passing cow” said Stanford PhD student Cecilia, “when I thought I heard the low oxygen klaxon. By the time I realised it was just two sheep I had already put on my safety mask and pulled the alarm to evacuate the tunnels.” She then commented “It took us three hours to get access to the tunnels again, and the noises and lights had caused the animals to panic, creating even more damage to clean up.”

This is not the first time a complex of tunnels has been overrun by farm animals. In the early 90s the London Underground was found to be infested with horses, which turned into a longterm problem and took many years to resolve.

Current estimates on the delay to the schedule range from a few weeks to almost a decade. Head of ATLAS operations, Dr Remy Beauregard Hadley, comments “I can’t believe all this has happened. They talk about Bovinae deposits delaying the turn on, and I think it’s just a load of bullshit!”
