All sector heads are meeting frequently with the Director General to discuss CERN-level issues.
In order to provide electronic data management capabilities as part of the Large Hadron Collider project, it enables the storage, management, organization and dissemination of large amounts of technical information, covering a wide range of fields.
The GAO provides an administrative support to the group, dealing with the arrivals/departures, attending the Section Leaders Meeting and filling the role of an executive assistant to the group leader.
A Gas Electron Multiplier is a type of gaseous ionization detector used in nuclear and particle physics and radiation detection. GEM detectors represent a muon system in CMS. CMS GEM detectors are made of three layers, each of which is a 50 micron thick copper-cladded polyimide foil. The ESA section performed the fiducialisation of the 216 GEM chambers of CMS and is in charge of their position measurement after installation in the experiment in the cavern.
Laser trackers offer accurate 3D measurement to reflectors, while the addition of six-degrees of freedom (6DoF) functionality enables the use of handheld probes, laser scanners and machine control solutions. This is one of the main instrument used in field.
The LEIR separates each of the long lead ion pulses received from Linac3 into four shorter packages. It takes about 2.5 seconds for the LEIR to speed up packets, in groups of two, from 4.2 MeV to 72 MeV. The ions then have the energy required to be sent to the Proton Synchrotron (PS). The LHC works with 592 ion packets per beam, so the LEIR takes about 10 minutes to supply enough packets for a full cycle.
Least square based global adjustment of measured data to estimate unknown parameters (e.g.: point coordinates). Main data processing software used by the surveyors at CERN to treat measurements acquired in the field.
The world’s largest and most powerful particle accelerator. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way.
