Compact
Muon Solenoid
The
Compact Muon Solenoid (CMS) is a next generation detector for
the new proton-proton collider (7 TeV + 7 TeV) called the Large
Hadron Collider (LHC) to be built in the existing 27km tunnel
near Geneva, Switzerland.
This collider will have the highest
center of mass
energy and have a luminosity of
 .
The general-purpose detector CMS is designed to detect the Higgs
particle as well as a host of new particles, such as super symmetric
partners of the standard family of elementary particles. The
collisions will also produce copious amounts of top quarks,
be a B physics factory and have large amounts of W's and Z's.
The CMS tracking system is designed to reconstruct
high-pT muons, isolated electrons and hadrons with high momentum
resolution and an efficiency better than 98% in the range

CMS
is also designed to allow the identification of tracks coming
from detached vertices. Such vertices arise from decays of b quarks,
which provide very useful signatures for a broad spectrum of new
physics.
The strategy is to provide a set of coordinate measurements of
sufficient precision and robustness such that track reconstruction
can be reliably performed based on a relatively small number of
measurements per track. CMS is a general purpose proton-proton
detector designed to run at the highest luminosity at the LHC.
It is also well adapted for studies at the initially lower luminosities.
The main design goals of CMS are:
1. A highly performing
muon system
2. The best possible
electromagnetic calorimeter
3. A high quality central
tracking
4. A hermetic Hadron
calorimeter
