The Collider Detector at Fermilab (CDF) experimental collaboration studies high energy particle collisions from the Tevatron, the world's former highest-energy particle accelerator. The goal is to discover the identity and properties of the particles that make up the universe and to understand the forces and interactions between those particles.
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]
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 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).
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 ...

The DRIFT detector's target material is a 1 m 3 cubical drift chamber filled with a low pressure mixture of carbon disulfide (CS 2) and carbon tetrafluoride (CF 4) gases (30 and 10 torrs (4.0 and 1.3 kPa), respectively). It is predicted that WIMPs will occasionally collide with the nucleus of a sulfur or carbon atom in the carbon disulfide gas ...
