CERN’s surveyors conduct diverse measurements to ensure, for example, accurate positioning of magnets, detectors and other equipment. They do so using techniques such as laser tracking and 3D scanning.

Two new wheels of the Resistive Plate Chambers (RPCs) of the muon system are being installed during the LHC’s first Long Shutdown (LS1).

The past two weeks have seen several pivotal steps taken towards achieving some of the key goals for CMS during the LHC’s first Long Shutdown (LS1).

One otherwise unremarkable day, the meeting of the CMS group at the University of Minnesota Physics Department took an unexpected, yet not entirely uncommon, detour to the pages of the web.

Being a young researcher in a collaboration the size of CMS can be daunting, and requiring to move to CERN even more so. A new scholarship has been set up with the aim of supporting master's students, PhD researchers or post-docs of the CMS Collaboration for a year's stay at CERN.

Mihir Khanna, from the Dhirubhai Ambani International School in Mumbai, India, was one of hundreds of high-school interns who come to CERN each year. He recounts his once-in-a-lifetime experience below.

CMS presented new results of searches for signatures of supersymmetry (SUSY) at the LHCP conference held in Barcelona, Spain in May and at the EPSHEP conference held in Stockholm, Sweden in July.

Despite the violent nature of the particle collisions that take place inside the CMS detector, the cathedral-sized cavern in which it sits thirty storeys underground exudes a certain peaceful calm.

The CMS Guitar has already visited Point 5 in the past but this was her first time underground, with the detector itself.

CMS is in many ways a living entity, undergoing change from time to time, with components being replaced or upgraded as their ability to handle the LHC's collisions reduces.

One of the biggest unanswered questions of particle physics is why the mass of the Higgs boson is relatively small when the Standard Model suggests a more natural value would be many

Over recent weeks, members of the TE-VSC group have been removing seven components of the beam pipe located at the heart of the CMS detector. The delicate operations involved have been performed in several stages as the detector opening work has progressed.

Observing a phenomenon for the first time helps us fine-tune our understanding of the Universe. CMS physicists found such a phenomenon in September 2012 in proton-lead collisions, an observation that has since been reinforced by much more data from such collisions collected in early 2013.

CMS measures production rates up to high transverse momenta

The members of the CMS group at the University of Maryland were impressed when they learned of Sascha Mehlhase’s LEGO model of the ATLAS detector. They were also jealous, and so a group led by Jeff Temple, Marguerite Tonjes, and Jaime Gomez decided to build a matching LEGO model of CMS.

Sometimes, everyday words are co-opted by scientists and used as technical terms. One of these is the word “berry”.

The Special Milner Fundamental Physics Prize is being awarded this week in recognition of the success of the international LHC Project, including the major contributions of the entire CMS collaboration, for the discovery of a Higgs boson as announced in July.

LHC access required: Time estimate ~ 2 years

On Saturday at 8.25am the shift crew in the CERN Control Centre extracted the beams from the Large Hadron Collider (LHC), bringing the machine’s first three-year running period to a successful conclusion. The following message marked the event on LHC Page 1: "No beam for a while.
