Celebrate the start of the 2012 LHC run with LHC experiments!

Participate in a special Hangout On Air from the +CMS Experiment, +ATLAS Experiment and +CERN control rooms, as we celebrate the re-start of the Large Hadron Collider in 2012, when the machine will operate at higher energies than ever before! Join us at the start of the year of discovery, and see where some of the world’s highest-energy particle physics experiments take place and ask questions to the scientists who conduct them.

The Large Hadron Collider (LHC) at CERN is the world’s biggest and most powerful particle accelerator, spanning the border between Switzerland and France. The LHC accelerates protons to nearly the speed of light and then smashes them together inside detectors like CMS some 40 million times a second to produce fantastic particles, many of which haven’t been around since the Big Bang.

CMS and ATLAS are the two general-purpose experiments at the LHC, located diametrically opposite each other on the 27-km ring. Both are hot on the trails of particles such as the Higgs boson, and are searching for signs of Supersymmetry and any exotic physics Nature has to offer.

Want to know what the differences and similarities between CMS and ATLAS are? Curious about the benefits of operating the LHC at 8 TeV and the challenges involved in it? Want an inside peak at the nerve centres of the LHC and its general-purpose experiments?

Comment below the original post by CMS ( and send us your questions, telling us why you would like to participate! A few of you will be invited to join the Hangout.

Be sure to add +CMS Experiment, +ATLAS Experiment and +CERN to your circles in order to be a part of this experience.

Important details:
The Hangout will be streamed live on the +CMS Experiment page.
Date: 4th April, 2012 (Wednesday)
Time: 16:00 – 17:30 Central European Summer Time (UTC +2) | Start times around the world:

Looking forward to following along.
Exciting milestone. by the way, for those people like me who are not physicists and may not know the language - TeV = Tera Volt. Electron volts are the unit of measure commonly used to describe atomic properties like ionization energy. You can read more about how amazing this milestone is, i.e. how much energy is being produced, on Wikipedia:
As a follow up question from my previous hangout Joe mentioned using diamond for the sensors to harden the sensor. If you look at the +CMS Experiment vs +ATLAS Experiment what sensor is better at handling the damage done by the experiments?
This is epic. Thanks for another great hangout.
+Jennifer Barr the TeV can be a bit misleading the energy is similar to a couple of flying mosquitos. But if mosquitos collide you will not find the higgs boson ;)
It's both energy and the fact that al that energy is in one single proton. No idea how many protons make up a mosquito.
well i've fixed the glitch with my webcam, and no work scheduled wednesday sooo,, i am 100% "good to go" this time :)))
i'm a masters student in theoretical physics, just finished doing a project on calculating and plotting branching ratios for the Higgs Boson's decay. Would definitely love and insight into the experimental part of it!
Oh man, this looks awesome. The news surrounding the completion of the LHC was what initially piqued my interest in physics. I'd certainly be interested to know what sort of technological barriers you've had to deal with in running such a high energy experiment and how the findings from the LHC have benefited areas out side of particle physics.
Suit up for the start of a new journey of extraordinary, but infinitesimal distances. Can frequencies become so high that they become point-like, in time?
This is so exiting! I was wondering how does a particle "decide" to decay in a set(s) of particles and not another. Also, I would love if you could explain what you do in a normal day. Or maybe what you did today, if it really varies from day to day :)
I will definitely join! I will use this account (the one I previously commented with is not the same). Thanks!
I am writing an article for +Australian Science magazine and would love to participate and ask the questions science enthusiasts (not scientists) would love to have answered.
I'd like to confirm my presence at the hangout tomorrow. CEFET's students are eager to participate. Thanks for the opportunity.
Will the Higg's speak if found, what language will it speak in when it begins to talk?
