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]
The main difference was the detector design; UA1 was a multipurpose detector, while UA2 had a more limited scope. [1] UA2 was optimized for the detection of electrons from W and Z decays . The emphasis was on a highly granular calorimeter – a detector measuring how much energy particles deposit – with spherical projective geometry, which ...
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).
The improved detector would use a new drift chamber for tracking and dE/dx measurements, a cesium iodide calorimeter inside a new solenoid magnet, time of flight counters, and new muon detectors. The new drift chamber (DR2) had the same outer radius as the original drift chamber to allow it to be installed before the other components were ready ...
Ionization chambers operate at a low electric field strength, selected such that no gas multiplication takes place. The ion current is generated by the creation of "ion pairs", consisting of an ion and an electron. The ions drift to the cathode while free electrons drift to the anode under the influence of the electric field.
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 ...

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 They were most widely used as research tools from the 1930s to the 1960s and have since been superseded by other technologies such as drift chambers and silicon detectors.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 ...
