Revised 2006 (see the various sections for authors). In this section we give various parameters for common detector components. The quoted numbers are usually based on typical devices, and should be regarded only as rough approximations for new designs. More detailed discussions of detectors and their underlying physics can be found in books by Ferbel [1], Grupen [2], Kleinknecht [3], Knoll [4]...

A brief review on the infrared concepts and photodetectors will be summarized. Emission of infrared photons has been observed in an ionization chamber filled with standard gases and some results are reported. Light produced by the electron drifting in the gaseous media has also been observed. Results are presented as a function of the electric drift field.

The Transition Radiation Detector (TRD) belongs to the central barrel detectors of the ALICE experiment at the LHC at CERN. It is composed of 540 large area drift chambers, with a total of 1181952 readout pads (1728 or 2304 per chamber). To ensure the optimal performance of the detector, designed for electron/pion identification and charged particle tracking, including triggering for high-pt el...

A measurement of the drift velocity of free electrons in liquid argon has been performed. Free electrons have been produced by photoelectric e ect using laser light in a so called \laser chamber". The results on the drift velocity vd are given as a function of the electric eld strength in the range 0:5 kV=cm j ~ Ej 12:6 kV=cm and the temperature in the range 87 K T 94 K. A global parametrizatio...

For the physics of the future, at or above 100 GeV center of mass energy, tracking devices will need: 1) Good segmentation, since particle densities are large. 2) Many samples along each track for pattern recognition, momentum resolution, and possibly dE/dx measurement. As an example, to do a good job separating two high momentum tracks from hadronic decay of the Z", angular segmentation 10 mra...

The study that we present is part of the preparation work for setup FOOT (FragmentatiOn Of Target) experiment whose main goal measurement double differential cross sections fragments produced in nuclear interactions particles with energies relevant particle therapy. focused on characterization gas-filled drift chamber detector composed 36 sensitive cells, distributed over two perpendicular view...
