The detection of charged particles within the chamber is possible by the ionizing of gas particles due to the motion of the charged particle. [14] The Fermilab detector CDF II contains a drift chamber called the Central Outer Tracker. [15] The chamber contains argon and ethane gas, and wires separated by 3.56-millimetre gaps. [16]
Charged particle tracking was performed in the central detector utilising a combination of multi-wire proportional chambers and drift chambers and hodoscopes. [8] Energy measurements were performed in the calorimeters. Unlike UA1, UA2 had no muon detector. Detector for the UA2 experiment.
The interior drift chamber had a length of 3.3 meters and a diameter of 4 meters, within which it contained 52,000 wires, making it the largest drift chamber ever constructed at the time. [5] The computer interpreting its data was able to calculate reconstructed particle trajectories with a precision of within 0.3%.
Therefore, chambers to detect muons are placed at the very edge of the experiment where they are the only particles likely to register a signal. To identify muons and measure their momenta, CMS uses three types of detector: drift tubes (DT), cathode strip chambers (CSC), resistive plate chambers (RPC), and Gas electron multiplier (GEM).
A spark chamber is a particle detector: a device used in particle physics for detecting electrically charged particles. They were most widely used as research tools from the 1930s to the 1960s and have since been superseded by other technologies such as drift chambers and silicon detectors. Today, working spark chambers are mostly found in ...
Particle identification is the process of using information left by a particle passing through a particle detector to identify the type of particle. Particle identification reduces backgrounds and improves measurement resolutions, and is essential to many analyses at particle detectors.

In experimental and applied particle physics, nuclear physics, and nuclear engineering, a particle detector, also known as a radiation detector, is a device used to detect, track, and/or identify ionizing particles, such as those produced by nuclear decay, cosmic radiation, or reactions in a particle accelerator. Detectors can measure the ...
