Heart transplant in the CERN accelerator

The complicated process requiring delicate 100 meters below the Earth in Geneva called by scientists as … heart transplant. Upgrading regard to CMS experiment at the Large Hadron Collider and enhance hunting scientists to new physical phenomena and answers to great mysteries. The CERN engineers replaced the detector pixels (pixel tracker) of CMS, which is designed to unravel the paths followed by the particles resulting from collisions.
That will take pictures of the particles located one above the other, and must then be separated. “It was as if we replace a camera of 66 megapixels with one of 124 megapixels» explained the BBC Austin Bowl, technical director of the CMS experiment (Compact Muon Solenoid).
Engineers began to disassemble the CMS just before Christmas and just last week was able to begin replacing the pixel tracker, the first half of which (weighing dozens kilos) was placed Tuesday and the second half yesterday.
“We were thinking long term when we decided to build this device. But it seems that the performance of the accelerator has improved so dramatically in the last two years, now is the time to make changes in order to exploit the maximum potential. For the new physics and the study of existing Natural “commented Bowl.
