large hadron collider

Everyone who’s not a scientist always seems so shocked that I can’t find meaningful employment in spite of having an advanced degree in theoretical physics, so you know what? Fuck it.

From now on, I’m just going to tell everyone that I had my physics license suspended after I accidentally used the Large Hadron Collider to rip a hole in the fabric of the time-space continuum.

Step Inside the World’s Largest Particle Accelerator in This 360-Degree Video

Recently, the BBC got to take a tour inside the largest particle physics laboratory in the world. Thankfully, it brought virtual reality cameras with it, providing an awesome tour.

To utilize the 360-degree features, simply drag your cursor around in the video to look up, down, and sideways. At the end, you get a sense of just how giant the LHC is, which makes discoveries like the one in 2012 possible. Back then, the collider detected the sub-atomic Higgs boson particle, a cornerstone of the Standard Model theory, which explains how particles interact.

On tonight’s episode of #Ponderlust, we go full quantum. That’s right, we’ll be talking about one of the most gargantuan structures humans have ever assembled – the Large Hadron Collider. 

In excitement for this, indulge in this science-gasmic Symphony of Science production all about the quantum world which underpin all of nature: particle physics! 

Wait, what?

The known universe is made up of 12 particles of matter (fermions - quarks, leptons, antiquarks, & antileptons - or matter/antimatter particles; bosons - gauge bosons & Higgs boson - or “force particles” that influence interactions between fermions) and 4 forces of nature (strong, weak, gravity, electromagnetism). The Large Hadron Collider (LHC) is essentially a research lab investigating where, why, when, and how those 12 particles and 4 forces came to be, and what that knowledge communicates to us about the life and death of the universe. 

Confusing? Fear not. Even the legendary physicist Richard Feynman stated 

I think I can safely say that nobody understands quantum mechanics.” 

Join us tonight at 8:30PM EST as we embark down the rabbit hole of particle acceleration and into a discussion of the Large Hadron Collider at CERN.

We want to hear from you too, so submit your #Ponderlust tagged questions, comments, or podcast suggestions and we’ll respond to them on the show!

ALICE (A Large Ion Collider Experiment) Detector, CERN

ALICE, one of seven total detector experiments at the Large Hadron Collider at CERN, aims to provide a deeper understanding of strongly interacting matter at extreme energy densities. ALICE is also optimized to study heavy ion (lead-lead nuclei) collisions at a center of mass energy of ~2.8 TeV. The resulting energy density and temperature are expected to be high enough to produce a quark-gluon plasma – its existence and properties are key issues in quantum chromodynamics. Recreating this primordial form of matter and understanding how it evolves is expected to shed much-needed light on questions concerning how matter is organized, the mechanism which confines quarks and gluons and the nature of strong interactions and how they ultimately result in generating the bulk of the mass of ordinary matter.

After closing for upgrades in February 2013, the Large Hadron Collider is coming back online later this month. 

The LHC has laid dormant, undergoing upgrades and tweaks in preparation for coming back online in the spring of 2015 for a (hopefully uninterrupted) three-year run of gathering more data. There remain plenty of unknowns for the researchers to investigate, such as the theorized existence of dark energy and dark matter, so the Collider’s future looks to be at least as busy and productive as its past. In order to spread this message and to give the public a better understanding of what the LHC does, CERN is using the present period of downtime to tour journalists around the particle accelerator’s cavernous detector stations and underground pipe network. It’s a fascinating look at how big industrial machinery is helping to answer questions about infinitesimally small things.

Hints of a new particle could change physics as we know it

A fluctuation in the data from the world’s most powerful particle smasher could turn all of physics on its head. In December, two different detectors at the Large Hadron Collider spotted the same strange fluctuation, which physicists say could hint at the existence of a brand-new subatomic particle. There’s just one problem with the “discovery.“

Large Hadron Collider ready to delve even deeper than ‘God particle’ as it switches back on at double power

CERN’s Large Hadron Collider is set to be switched back on in March — hoping that a £97 million upgrade could push it to even greater discoveries, after it found the “God particle” in 2012.

The second three year run of the huge atom smasher will begin in March 2015. The Large Hadron Collider has been switched off since its last run finished in 2012.

The world’s largest particle collider has been undergoing a £97 million upgrade since then, as scientists comb through the data found during the last run.

It is being cooled back down ready for the switch on, and is almost at its operating temperature of 1.9 degrees above absolute zero, or about minus 271.25 degrees Celsius. Scientists are also testing out the equipment and earlier in December activated one of the magnets required to fire atoms around the collider.

Scientists are now gearing up to turn both on at once, in 2015. That will produce collisions of a scale never achieved by any accelerator in the past, equivalent with 154 tons of TNT.

The extra power will allow the CERN’s numerous experiments to look into deep mysteries of the universe, such as dark matter.

The Large Hadron Collider was used in 2012 to confirm the existence of the Higgs boson, known as the God particle, which explains the very beginning of the universe.

The Compact Muon Solenoid (CMS) experiment at CERN (the European Organization for Nuclear Research) is one of two large general-purpose particle physics detectors built on the Large Hadron Collider. The goal of the CMS experiment is to investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that might make up dark matter. It’s 25 metres long, 15 metres in diameter, and weighs in at 12,500 tons. 

In July of 2012, along with ATLAS (A Toroidal LHC Apparatus), CMS discovered a boson very similar to the Standard Model Higgs Particle, but further research was required to determine if the boson found was, in fact, the Higgs Particle. In March of 2013, CERN announced it was now certain it has discovered the Higgs boson. In order to make this final determination, the dataset was analyzed to see if the quantum properties of the boson discovered in July of 2012 matched properties of the Higgs boson currently predicted by physics. After tests in both CMS and ATLAS, it was confirmed that the particle possessed those properties.

This discovery is monumental because it seems to confirm the existence of the Higgs field, which is pivotal to the Standard Model and many other theories within the realm of particle physics. Physicists should now be allowed to finally validate the Standard Model’s approach to fundamental particles and forces, guide further theories and discoveries in particle physics, and potentially over time lead to developments in “new” physics.

The LHC is preparing to restart!

The Large Hadron Collider sets its sights on dark matter

After finding the Higgs boson, the LHC has had a refit to enable it to operate at even greater extremes – and to solve more questions about the beginnings of the universe

By Robin McKie

There is no shortage of superlatives that can be applied to the Large Hadron Collider near Geneva, though many are strange and unusual. For a start, the huge underground device, which batters beams of protons into each other at colossal energies, can fairly claim to be the coolest place on Earth. Bending protons as they hurtle round the LHC’s circular 27km tunnel turns out to be a chilly business.

Thousands of huge magnets are needed to control the beams and these have to work with complete efficiency. To achieve this, the device is refrigerated to two degrees above absolute zero on the thermodynamic temperature scale: -271C, a temperature at which electric currents flow without resistance. In this way, the collider’s magnets can work to their maximum potential.

Today in a White House ceremony, the U.S. Department of Energy, U.S. National Science Foundation and CERN – the renowned European laboratory on the Switzerland-France border – signed a cooperative agreement to enable continued scientific discoveries in particle physics. The agreement replaces the former US-CERN agreement, signed in 1997 and that was set to expire in 2017. While the facility is involved in many particle physics experiments and collaborations, it is best known for its Large Hadron Collider. NSF funds the operations and maintenance for the ATLAS and CMS detectors that observe collision byproducts on opposites sides of the LHC ring.
