Final Detector in Place at the Large Hadron Collider
One of the most complicated construction projects ever attempted reached a major milestone today. The final large detector element for the ATLAS instrument was lowered into the Large Hadron Collider. And this baby's big. Weighing in at 100 tonnes. When the collider finally comes online, this instrument will measure the cascade of particles generated in proton proton collisions.
The ATLAS detector itself is enormous, weighing 7,000 tonnes and measuring 46 metres long, 25 metres high and 25 metres wide. It has 100 million sensors that will track all the particles that freeze out when protons are smashed together at tremendous energies.
And so today, the final element for ATLAS was plugged into its permanent home. It's known as a "small wheel", and there are two of them in the detector. Compared to the full cheap canada goose ATLAS instrument, it only weighs 100 tonnes, and measures a mere 9.3 metres across.
Since the whole detector is located deep underground, engineers had to lower each piece down a 100 metre shaft. And they've been installing pieces this way since 2003. In the case of the small wheel, it was even harder canada goose clearance to get it down.
"One of the major challenges is lowering the small wheel in a slow motion zigzag down the shaft," explained Ariella Cattai, leader of the small wheel team, "and canada goose outlet online uk performing precision alignment of the detector within a millimetre of the other detectors already in the cavern."
With all of ATLAS' parts in place, it's canada goose outlet shop time to enter the commissioning phase. Researchers will test all of the parts together in preparation for the first tests this Summer.
By this time next year, physicists might have many more answers about the nature of canada goose outlet sale gravity, dark matter, and nature's preference for matter over dark matter. And I'm sure they'll have even more new questions. But that's how science works.

I agree with about being there!
Well CERN, you buy, I fly. As a MAJOR Physics event, shouldn you include a member of the General Public from the top 3 nations involved? The technology may be a couple of years (HA!) ahead of public user access but, with the right uk canada goose outlet imaginations more end user products and tech. will be available for Patent. Oh yes, what is your plan to contain any particals?
And, to all the Nay Sayers, isn this fun?!? Just imagine that Mankind Survives! Just think of what you will accomplish! With the proper imaginations and skills that you can be a part of.
France builds Doomsday Machine massive machine is a magnetic ring https://www.ferienhaus-starnberger-see.de 27 kilometers in circumference: Ultimately, uk canada goose it will collide beams of protons at canada goose outlet canada an energy of 14 TeV. Additionally, beams of lead nuclei will be also accelerated, colliding together with an energy of 1150 TeV. This explosion, to those of us who count ourselves among the worried masses, appears to be an ominous foreshadowing of what could eventually become the Second Coming of the BigBang Close you eyes and pictuer this. You have an post, but have failed to consider the fact that particles are constantly slamming into Earth atmosphere with MANY times the energy that the LHC will be able to muster. Let me just state that again UHECR particles, or the so called oh my god particles, have been recorded with estimated energies of up to 3 eV. That is at least two hundred thousand times more energetic than your 1150 TeV collisions. That the universe hasn already condensed into a soup canada goose outlet parka of more exotic particles as you suggest may happen as a result of these UHECRs seems to indicate to me that, from the LHC at least, we have nothing to fear.
I dont know where to start, but I need to start somewhere, thus would you take the time to read this? My name is Steven Turner, and I am a physicist in my own right. I started writing about psychology when I was thirteen years old and continued until I was twenty two. I had not had a teacher of this, so I did all my examinations alone. When I was about twenty canada goose outlet black friday three, my mind began changing focus towards the way our universe works. Again having no teacher, I had to figure it out alone. I wanted to determine how our atom works. I began testing personal theories about simple mathematical codes that the universe could use. Instead of trying to actually see what was going on goose outlet canada in an atom, I tried to establish the only possible code that an atom could operate with. This seemed easier for I had no access to a collider, which I had no idea even existed at the time. I spent roughly three years figuring out a code that worked easily, simply, and well. Once I got this done, I signed up for a few classes at a college in order to slightly test my theories. I took a simple algebra class and a psychology class. Canada Goose Outlet I tried to show the math teacher some of my work, but not only did he seem to look at me as lesser than him, but he also seemed completely uninterested with my years of work. I suppose I really cant expect more from a teacher thats just wants to teach his class, and pass no judgment, but I attained multitudes of universal information during attendance of the class. During my psychology class, it was as if I were at home, seeing things I had never noticed before. Within a few cheap canada goose classes I noticed that the makeup of the mind was tightly comparable to the composure of the atom. I began connecting the known knowledge of psychology, with my theories of what I now call atomics, or universal mathematics. Soon I had canada goose outlet new york city begun creating something I would like to introduce to the world of science, as ((Psychological Atomics)). I believe I can explain how our minds follow canada goose factory sale the exact nature of atomic signatures, signals, transfers, disturbances, equations, and much more. I may not be a professional in the eyes of acknowledged world scientists, but I do have a great deal of heart for this. I believe that the universe is so simple that it may be easy to decipher its mechanisms by comparing everything we see around us. Mathematics is universal and associates with every natural world existence. Instead of just breaking the atom canada goose outlet reviews down I went straight for what I like to call the ((Bottom)). After briefly reading into some reports, I canada goose jacket outlet found that many call the bottom, the ((God particle)). I am trying to crack the atom code in a mobile home, within a small town canada goose outlet store uk of Arizona. I CAN DO IT!! All I need is a little time with professionals that I dont know how to get in Canada Goose Parka touch with. I have put atomics into algebraic and geometric formats and although I dont have this code complete, I think I am closer than I should be. I can easily explain why light travels faster than sound, and why we dont age while traveling at the speed of light. Time measurement is easy to define and calculate with this theory. I can make it complex enough to evade many, or easy enough for a grade school student to understand. I have over five hundred pages of journalism and diagrams to share with the scientific world, and whether or not it can ever be taken seriously, I would like to share it with someone. I am also timid to share it, in possibility that it will be stolen, but we all deserve and share the same knowledge together do we not? It doesnt matter who figures these things out, it only matters that we do. I believe that I have a good idea of what happened seven steps before the Big Bang. This is all I am comfortable sharing at this point.
