Hadron collider detectors

The Large Hadron Collider.

The construction of the Large Hadron Collider (LHC) has been a massive endeavour spanning almost 30 years from conception to commissioning. Building the machine with the highest possible energy (7 TeV) in the existing large electron-positron (LEP) collider tunnel of 27 km circumference and with a tunnel diameter of only 3.8 m has required considerable innovation. The first was the development o...

The Large Hadron Collider LHC

The Large Hadron Collider Project LHC was approved by the CERN Council in December 1994. Commissioning with beam will start in the second half of 2005. The paper discusses the most important parameters, the general layout of the LHC octants, the status of the experiments ALICE, ATLAS, CMS and LHC-B, proton injection using the PS Booster, and the proton synchrotrons PS and SPS. Also described ar...

Detectors for the Linear Collider

Prospects for Collider Vertex Detectors*

This talk discusses the technologies available for vertex detection and the restrictions imposed by event topologies and multiple coulomb scattering. It will be shown that ultimate performance limits for collider detectors are set by how close active detection starts relative to the interaction region. This in turn is determined by the machine characteristics and the care taken to provide colli...

Really Large Hadron Collider Working Group

A summary is presented of preliminary studies of three 100 TeV center-of-mass hadron colliders made with magnets of different field strengths, 1.8T, 9.5T and 12.6T. Descriptions of the machines, and some of the major and most challenging subsystems, are presented, along with parameter lists and the major issues for future study.
