replacement of the heart of the CMS experiment - the pixel #detector. Part2
This week, one of the Large Hadron Collider’s experiments gets a “heart transplant”. --- Physicists and engineers are replacing the heart of the CMS experiment - the pixel #detector. This will improve CMS’s ability to make precise measurements on aspects (Image: CERN)

Collision events recorded by CMS in 2016
An event where two Z candidates are produced and each decay into two muons, each given by the red lines. This event has 27 reconstructed vertices. (CMS SketchUp model by Tai Sakuma) (Image: CERN)

CMS central beampipe installation
The beam pipe, the "heart" of the detector, is being installed inside the CMS detector. Here the LHC beams collide at the Interaction Point. It will be one of the last elements of the experiment to be installed before closing the CMS detector. (Image: CERN)

HCAL activities in CMS cavern
Some modules are being removed inside the magnet. During this year of Long Shutdown 2 (LS2) CMS groups work continuously on the many upgrade activities and detector improvements needed to prepare CMS for the Run3 at the LHC and even further forward in preparation for the upgrade to High Luminosity LHC (HL-LHC).
