E896 was designed to search for the predicted short-lived six-quark H0 di-baryon. The goal is to enhance the existing knowledge by extending the search into regions of shorter lifetimes (approximately half that of the lambda) and via exploring a new creation channel, that of the coalescence of two lambdas. Two main tracking chambers are used, a distributed drift chamber positioned to measure low-pt and high-rapidity neutral particle decay products and a silicon drift detector array which measures particle production at mid-rapidity. Both detectors are also investigating lambda polarization, over their respective coverages, for Au-Au collisions at 11.3 GeV/nucleon. The current status of the H0 di-baryon search and preliminary results of the strange particle production and polarization measurements will be presented.

Abstract The AGS Experiment 896 was designed to study strangeness production in Au—Au collisions at 11.6A GeV/c, in particular the formation of a six-quark di-baryon the H 0 . Heavy ion collisions provide favorable conditions for the H 0 formation either via coalescence of two Λ particles (owing to the large Λ production cross section) or direct production from the possible formation of a quark-gluon plasma. E896 also measured strange meson and baryon distributions from mid-rapidity. Preliminary results from this experiment are presented as well as details of the expected sensitivity for the H 0 search.

Abstract We report the results of tests of prototype proximity mesh dynode photomultiplier tubes (FEU-527) manufactured by MELS. These tubes were compared with similar Hamamatsu models R5505/R3432-01 to determine their suitability for use in the Time-of-Flight (TOF) subsystem of the Solenoidal Tracker at RHIC (STAR) project. Gain and timing characteristics of these tubes were measured both with and without a magnetic field. The results show that some of the Russian prototype tubes meet the requirements for the STAR TOF subsystem.
