In CBM open charm mesons will be identified by reconstructing their secondary decay vertices. This requires a vertex detector with very good secondary vertex resolution (σSV ∼ 50 μm along the beam axis). To match this requirement, a highly granular pixel detector with excellent spatial resolution (∼ 5 μm) and minimum material budget (few 0.1 %X0) will be(More)
HADES is a second-generation dilepton spectrometer for hadron and heavy ion physics ut the SlS Accelerator facility of GSI Darmstadt. Germany. The physics programme requires the detection of rare events in an environment of several GByteds of background data. This paper describes the dedicated trigger system which works rogether with (I pipefined data(More)
The CBM experiment will investigate heavy-ion collisions at beam energies from 8 to 45 AGeV at the future accelerator facility FAIR. The goal of the experiment is to study the QCD phase diagram in the region of moderate temperatures and highest net-baryon densities in search of the first-order phase transition from confined to deconfined matter at the QCD(More)
Institut für Kernphysik, Goethe-Universität, Frankfurt am Main For the design of the Micro Vertex Detector (MVD) for the CBM experiment we are following two approaches. The first approach uses advanced technologies regarding sensor integration and interconnections. The second one is a more conventional approach with well definded building blocks (sensor,(More)
The general-purpose trigger and readout board (TRBv2) with on-board DAQ functionality and extensibility through add on cards has been developed and was used successfully in two beamtimes in the year 2007. The functionality of the TRBv2, already roughly outlined in [1], is described in [2]. Several add on modules, which enhance the functionality/connectivity(More)
The Second Level Trigger of the HADES (High Acceptance DiElectron Spectrometer) detector[1] is a very selective trigger[2] able to identify electron/positron pairs in a given invariant mass range. It consists of dedicated hardware, Image Processing Units (IPUs) which detect electron signatures in several subdetectors. A matching unit combines this(More)

Dilepton production has been measured with HADES, the " High Acceptance DiElectron Spectrometer ". In pp collisions at 2.2GeV kinetic beam energy, exclusive η production and the Dalitz decay η → γe + e − has been reconstructed. The electromagnetic form factor is well in agreement with existing data. In addition, an inclusive e + e − spectrum from the 12 C+(More)
The Micro-Vertex Detector (MVD) [1] of CBM is intended to detect the hadronic decays of open charmed particles by means of the identification of their displaced decay vertex. Therefore the MVD is located close to the collision point and will be exposed to the very high track densities from the high heavy ion collision rates foreseen in CBM. The design of(More)
