TL;DR: In this paper, the CERES/NA45 experiment at CERN uses a silicon pad detector with 64 ring shaped pads for first level triggering on minimum bias proton-nucleus as well as on high multiplicity ion-ion collisions.
Abstract: The CERES/NA45 experiment at CERN uses a silicon pad detector with 64 ring shaped pads for first level triggering on minimum bias proton-nucleus as well as on high multiplicity ion-ion collisions. In addition, the counter serves as a multiplicity detector to estimate the energy density obtained in the collision. The design and performance of the pad counter in the laboratory and under real beam conditions together with the first level trigger electronics are reported.

TL;DR: In this paper, results from the HELIOS External Spectrometer on kaon production in 200 GeV/A S + W and p + W collisions are presented. But the results at y = 1.0−1.5 are compared with neutral strange particle results at midrapidity.

TL;DR: In this paper, the authors present measurements of the rapidity and transverse-momentum distributions of the protons emitted in S+W, O+W and p+W reactions at 200 GeV/A around the target rapidity (y=1).
Abstract: We present measurements of the rapidity and transverse-momentum distributions of the protons emitted in S+W, O+W, andp+W reactions at 200 GeV/A around the target rapidity (y=1). The rapidity density rises linearly with the transverse energy for all three systems, but the slope forp+W is much steeper than for O+W and S+W. The rapidity density forp+W is much higher than predicted by summing single nucleonnucleon collisions without any nuclear effects, indicating substantial rescattering of the produced particles. The predictions of the VENUS 3 model, including rescattering, show reasonable agreement with the data for all three systems. We do not have evidence for a strong collective flow of the outgoing particles.
