CERN Accelerating science

In the past two weeks we had the final round of approvals for Moriond EW that is taking place during the week of Mar 17-22. The results approved are:

A workshop on Alignment and Calibration (AlCa), organized by the PPD and DPG Coordinations, was held at CERN from the 17th to the 19th of March (https://indico.cern.ch/event/306000/).

The last few months have seen several important objectives of the CMS LS1 programme completed, giving increasing confidence in the final outcome.

The Tracker is a subdetector that is located closest to the collision point of the LHC’s particle beams inside the CMS detector. It must face an onslaught of billions of particles flying through it each second of operation.

After two years of planning, one year of implementation, and two million CHF worth of investments, the Tracker project has achieved its most important goal to enable the “Tracker Going Cold”.

Building robots, using 3D printers and testing chemical reactions is an excellent way to spend your Saturday.

CMS has many different safety systems installed in the underground experimental area. These are designed to protect the detector and all the associated electronics as well as the cavern itself. In case of fire, the last line of defence is the High Expansion Foam System.

The first part of the CMS endcap calorimetry, as seen by particles coming from interactions in the centre of the detector, is the "ECAL Preshower" or "ES" for short.
