“…Each wire can be independently moved inside the beam halo in order to adjust the interaction rate. The reconstruction of primary and secondary vertices is performed by a silicon micro-strip Vertex Detector System [4]. The main tracker is divided into the Inner Tracker [5], composed of micro-strip gas chambers with gas electron multipliers, and the Outer Tracker [6] made of honeycomb drift cells.…”

A statistical method which uses a combination of two subdetectors to monitor the luminosity in high energy interactions is presented. To illustrate its performance, this method was applied to random triggered minimum bias data collected in the commissioning period of the HERA-B experiment in spring 2000. It is found that luminosity estimates with an intrinsic systematic error of 3% can be obtained.

“…The data presented here were obtained using a carbon wire and a titanium wire separated by 3.3 cm along the beam direction. The resolution of the reconstructed dilepton vertices of 0.6 mm along the beam direction [13] allows a clear association of the interaction to a specific target wire. The analysis presented is based on data collected during a short commissioning run in summer 2000.…”

“…The latter is separated into an inner tracker (ITR) close to the proton beam-pipe and an outer tracker (OTR) farther out. The VDS [32] features 64 double-sided silicon microstrip detectors arranged in eight stations along, and four quadrants around, the proton beam. The silicon strips have a readout pitch of approximately 50 µm.…”

Inclusive differential cross sections dσ pA /dx F and dσ pA /dp 2 t for the production of K 0 S , Λ, andΛ particles are measured at HERA in proton-induced reactions on C, Al, Ti, and W targets. The incident beam energy is 920 GeV, corresponding to √ s = 41.6 GeV in the proton-nucleon system. The ratios of differential cross sections dσ pA (K 0 S )/dσ pA (Λ) and dσ pA (Λ)/dσ pA (Λ) are measured to be 6.2 ± 0.5 and 0.66 ± 0.07, respectively, for x F ≈ −0.06. No significant dependence upon the target material is observed. Within errors, the slopes of the transverse momentum distributions dσ pA /dp 2 t also show no significant dependence upon the target material. The dependence of the extrapolated total cross sections σ pA on the atomic mass A of the target material is discussed, and the deduced cross sections per nucleon σ pN are compared with results obtained at other energies.
