Photograph collection until completion of "Ultra large experimental device" Atlas "for Higgs particle detection

"Why do things have weight?"Higgs particle"We can understand this mystery if we can find a strange particle called "Higgs particle called God's elementary particle and the discovery of SUSY (Susie) particle of dark matter candidate which is said to occupy 24% of the universe , Two large experiments by the LHC accelerator (Large Hadron Collider, Large Hadron Collider Accelerator) which is expected to discover the profound physical law which dominates the universe which no one expected,Atlas experiment(ATLAS = A Troidal LHC Apparatus) and CMS experiment (Compact Muon Solenoid) have finally come to light.

CERN - the European Organization for Nuclear Research


"ATLAS and CMS experiment report current status on Higgs particle search"According to the latter half of 2012, there is enough data to give the final answer on the presence or absence of Higgs particles," We can not reach with the data collected at the time of the present time, but we found Higgs particles with properties different from the standard theory If you find out that Higgs' particles predicted by the standard theory does not exist, you can see the new physics in experiments with LHC design values ​​after 2014 Whether ATLAS and CMS will make results on the existence of Higgs particles in future, LHC can be said to be an accelerator capable of studying new physics. "

A state of the announcement that took place on the evening of 13th December (Tue) in Japan time





That's why let's take a look at the photograph of the trajectory of "Atlas" to be said as a catastrophic detector of this detector until completion.


As for the atlas and experiments related to it, you can roughly understand by reading the following page in order, and you will be able to know which of the following pictures is what.

Construction of LHC and Atlas

LHC plan to challenge the most extreme world (3)

Great prediction of elementary particle theory

Interesting Japanese superconducting technology

Atlas semiconductor detector

A decision of 1/40 millionth second

Atlas is a huge detector with about 2200 meters in height, 44 meters in length and 7,000 tons in weight, where about 1,800 physicists from 37 countries have participated.


Scientists gathered for Atlas


This is a superconducting toroid electromagnet (end), Atlas uses 8 coils × 2 sets, total weight is 48 tons.




Liquid argon electromagnetic calorimeter, liquid argon hadron calorimeter




Base of superconducting toroid electromagnet (barrel part)








Silicon microstrip detector



Anyway it's huge



A silicon microstrip detector that is approaching completion



Compared to the size of the person in the center lower part, you can see how big it is


A huge








A signature



Still under construction




Muon trigger detector








Again the superconducting toroidal electromagnet





It has become quite a form



Induction of superconducting toroid electromagnet




Installation




Connection








It is too overwhelming.





This is the control center



First experiment



Happy



Successful experiment


It continues the adjustment further, it reaches to now





By the way, watching this page uses the web, that is, the Internet, but it was computer engineer of CERN (CERN) that created the web (World Wide Web)Tim Berners-LeeMr.KEK(High Energy Accelerator Research Organization) said, "I was wondering how to share the same information instantaneously among researchers of high energy physics experiment teams scattered throughout the world, 1990 Since it was said that the invention of the Web came close to the end of the year ", as the byproduct of this super large experiment is already changing the world already, the moment when the history of the world is changed greatly later There is almost no mistake that we are approaching slowly, but surely.
