摘要
The Phobos experiment concluded its first year of operation at RHIC taking data in Au-Au nucleus collisions at roots(nn) = 65 GeV and 130 GeV/nucleon pair. First preliminary results of the performances of our silicon detectors in the experiment are summarized. The Phobos experiment uses silicon pad detectors for both tracking and multiplicity measurements. The silicon sensors vary strongly in their pad geometry. In this paper, we compare the signal response, the signal uniformity and signal-to-noise performance as measured in the experiment for the different geometries. Additionally, we investigate effects of very high channel occupancy on the signal response. (C) 2001 Elsevier Science B.V. All rights reserved.
