Abstract

A large-angle multiplicity detector (LAMD) system has been developed and used in the BNL experiment E854, relating to antiproton-nucleus interactions. The purpose of the BNL experiment E854 was to search for the predicted formation of hot hadronic matter by energetic antiproton absorption on a range of nuclei. This experiment probed the high-temperature-low-density region of the nuclear matter phase diagram. The LAMD system performed well with an energetic antiproton beam. Charged particle multiplicity distributions from p annihilations were measured. The design and performance of the LAMD system are outlined. >

Abstract

TPCs (time projection chambers) used in E-810 at the AGS (alternating gradient synchrotron) were exposed to fluxes equivalent to more than 10/sup 7/ minimum ionizing particles per second to find if such high fluxes cause high changes or distortions of the electric field. Initial results of these and other tests are presented and the consequences for the RHIC (relativistic heavy ion collider) TPC-based experiments are discussed. Measurements of distortions due to ion loading in the E-810 TPCs have been measured to be small even at very high effective particle fluxes. This results supports the use of TPCs at RHIC, even at the highest planned luminosity. In addition, measurement of two-vertex resolution and reconstruction efficiency at high track density showed that a TPC is an excellent detector for the RHIC. >

Abstract

A TPC (time projection chamber) detector system has been developed to function in the very-high-multiplicity environment of relativistic-heavy-ion experiments. A TPC was chosen because it directly gives three-dimensional points on the tracks, which is a very significant help for track-finding. Of prime importance is a combination of high efficiency, low noise, and two track resolution capability. A significant development is a system of hybridized, high-sensitivity, on-chamber digitizing electronics. A description of the TPC modules, the digitizing electronics, and test results is given. >
