Time projection chamber

A promising development in this direction is the DRIFT detector Snowden-Ifft, Martoff Burwell (2000). This detector consists of a negative ion time projection chamber, the gas in the chamber serving both as WIMP target and as ionization medium for observing the nuclear recoil tracks. The direction of...

The proposed telescope (Aprile et al. 1992a) combines a liquid xenon time projection chamber (LXe-TPC) as calorimeter and position sensitive 7-ray detector with a coded aperture mask to achieve precise measurement of the energy and angular distribution of 7-ray sources in the 0.3-10 MeV energy region (Fig. 1). The coded mask is a 43x41 element URA, with elements... 

Large quantities of ultrapure liquid argon would be required in the realization of a large time projection chamber for the study of cosmic neutrinos or proton decay.

Fig. A.4 Apparatus used for the study of strangeness production in relativistic heavy ion collisions, NA36, performed on the SPPS. The decay products of As and K s are detected in a Time Projection Chamber (TPC) located in superconducting Helmholtz coils. Calorimeters located downstream of the TPC correlate the strangeness production with energy flow.

A variety of technologies have been studied double-sided silicon strip detectors, silicon pixel devices, gaseous microstrip detectors, and micro- and radial time projection chambers. 

At the time of writing a new EU infrastructure project EUROCHAMP (co-ordinator P. Wiesen < wiesen uni-wunnertal.de >) has as its main goal the integration of all European chamber facilities to improve studies on atmospheric chemical systems and also to open simulation facilities for impact studies.
