“…The telescope implemented in 1995 consisted of a 3-inch detector followed by a 4-inch detector, the latter of the novel AZTEC design [64] which eliminated the focusing problem. The spacing of the two detectors was 14.3 (15.0) mm and the distance from the target centre to SiDC-1 amounted to 98.5 (110) mm in 1995 (1996).…”

Abstract. We present the combined results on electron-pair production in 158 GeV/n Pb-Au ( √ s= 17.2 GeV) collisions taken at the CERN SPS in 1995 and 1996, and give a detailed account of the data analysis. The enhancement over the reference of neutral meson decays amounts to a factor of 2.31±0.19 (stat.) ± 0.55 (syst.) ± 0.69 (decays) for semi-central collisions (28% σ/σgeo) when yields are integrated over m > 200 MeV/c 2 in invariant mass. The measured yield, its stronger-than-linear scaling with N ch , and the dominance of low pair pt strongly suggest an interpretation as thermal radiation from pion annihilation in the hadronic fireball. The shape of the excess centring at m ≈ 500 MeV/c 2 , however, cannot be described without strong medium modifications of the ρ meson. The results are put into perspective by comparison to predictions from Brown-Rho scaling governed by chiral symmetry restoration, and from the spectral-function many-body treatment in which the approach to the phase boundary is less explicit.

“…the increase of the readout node voltage with the arrival of one electron. With --ctot (2) where U0 is the increase of the output voltage, Qj the injected charge and Ct0t the total readout node capacitance, an X-ray of 6 keV stimulates a voltage change of 2.6 mV. This corresponds to a sensitivity of 1.6 V / electron.…”

Silicon Drift Detectors (SDDs) with integrated readout transistors combine a large sensitive area with a small total readnode capacitance and are therefore well suited for high resolution, high count rate X-ray spectroscopy. The low leakage current level obtained by elaborated process technology makes it possible to operate them at room temperature or with moderate thermo-electric cooling. The monolythic combination of several SDDs to a multichannel drift detector solves the limited of size and allows for the realization of new physics experiments and systems. Up to 3 cm2 large SDDs for spectroscopic applications were fabricated and tested. Position sensitive X-ray systems are introduced.The description of the device principle is followed by the introduction of the multichannel drift detector concept. Layout, performance and examples of current and future applications are presented.

“…Negative pions are identified using the differential energy loss dE/dx along their tracks in the TPC. For vertex reconstruction and tracking outside the magnetic field, two radial Silicon Drift Detectors (SDD) (32) are placed at 10 and 13 cm downstream of a segmented Au target. Negative pions are reconstructed by matching track segments in the SDD doublet and in the TPC using a momentum-dependent matching window.…”

Differential triangular flow, v 3 (p T ), of negative pions is measured at √ s NN = 17.3 GeV around midrapidity by the CERES/NA45 experiment at CERN in central PbAu collisions in the range 0-30% with a mean centrality of 5.5%. This is the first measurement as a function of transverse 1 arXiv:1604.07469v2 [nucl-ex] 12 Aug 2016 momentum of the triangular flow at SPS energies. The p T range extends from about 0.05 GeV/c to more than 2 GeV/c. The triangular flow magnitude, corrected for the HBT effects, is smaller by a factor of about 2 than the one measured by the PHENIX experiment at RHIC and the ALICE experiment at the LHC. Within the analyzed range of central collisions no significant centrality dependence is observed. The data are found to be well described by a viscous hydrodynamic calculation combined with an UrQMD cascade model for the late stages.
