On one side of the detector is a high-voltage cathode plane, used to establish a drift electric field across the TPC. Although the exact electric potential at which this is set is dependent on the detector geometry, this high-voltage cathode typically produces a drift field of 500 V/cm across the detector. [10]
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 MicroMegas detector (Micro-Mesh Gaseous Structure) is a gaseous particle detector and an advancement of the wire chamber.Invented in 1996 by Georges Charpak and Ioannis Giomataris, [1] Micromegas detectors are mainly used in experimental physics, in particular in particle physics, nuclear physics and astrophysics for the detection of ionizing particles.
In particle physics there have been many devices used for tracking. These include cloud chambers (1920–1950), nuclear emulsion plates (1937–), bubble chambers (1952–), [ 3 ] spark chambers (1954-), multi wire proportional chambers (1968–) and drift chambers (1971–), [ 4 ] including time projection chambers (1974–).
There are two aspects of the muon detectors: the planar drift chambers and scintillators. There are four layers of planar drift chambers, each with the capability of detecting muons with a transverse momentum p T > 1.4 GeV/c. [9] These drift chambers work in the same way as the COT. They are filled with gas and wire.
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 ...
A set of 1200 chambers measuring with high spatial precision the tracks of the outgoing muons; A set of triggering chambers with accurate time-resolution. The extent of this sub-detector starts at a radius of 4.25 m close to the calorimeters out to the full radius of the detector (11 m).
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 ...
