| Abel, Norbert | Enhanced Design Flexibility Based on Partial Reconfiguration |
| Xilinx FPGAs like Virtex2, Virtex4 or Virtex5 provide the possibility to be reconfigured partially and dynamically. This means, that parts of the hardware can be exchanged while the rest of the circuit is running untouched. Nowadays, typical applications of dynamical partial reconfiguration (DPR) are streaming, low power, reconfigurable coprocessors and fault tolerance. Furthermore, DPR can help to increase design flexibility and scalability while the design itself becomes smaller at the same time. Regarding to the DAQ (data acquisition) in high energy physic experiments, all these topics are of interest. Unfortunately, today it is still very complex to use DPR, since the developer has to understand the reconfiguration techniques in detail to be able to use DPR. That causes a small usage of DPR in DAQ systems, yet. In the following we want to present a DPR framework that makes it possible to use the complete DPR techniques without going in detail with the underlying technology. Thus, our framework enables regular DAQ developers to use all the advantages coming with partial reconfiguration. | |

| Gebelein, Jano | Fault-tolerant Logics for FPGA |
| The increasing use of SRAM-based reconfigurable architectures at important areas of research and development (like particle accelerators and space applications) brings new, currently partially unattended effects on top. An already well known, but nevertheless important problem of such systems is its susceptibility to radiation which increases in conjunction with particle flux and energy. Regarding to current knowledge, errors induced by Single Event Upsets (SEU) and Single Event Transients (SET) are handled exclusively in hardware by the use of spacial and temporal redundancy features. Our field of research is to extend conventional fault tolerance to multiple layers of embedded computer systems, starting with the FPGA bit layer and ending up in the software application layer to get a maximum of radiation tolerance in systems running FPGA Linux in radiation susceptible environments. Only a collaboration of all these layers is able to create an adequate amount of data security and process integrity. | |

| Jipa, Alexandru | On the resonance matter formation in nucleus-nucleus collisions at energies higher than 1 A GeV |
| In nucleus-nucleus collisions at energies higher than 1 A GeV a new phase of the nuclear matter, named resonance matter, could appear. In this work we discuss some aspects related to the formation of this phase. Some experimental results - obtained, mainly, in SKM 200 Collaboration and, also, in BRAHMS Collaboration - as well as some predictions of some simulation codes (SHARE Code, mainly) for nucleus-nucleus collisions at FAIR CBM energies are presented. | |

| Manz, Sebastian | Status of the Read Out Controller for the FEET boards. |
| The FEET board is utilized as front-end-electronic of the ToF detector. The configuration, the synchronization and the data read out shall be done using the same hardware (a SysCore V2 board), that is already used for the n-XYTER read out. The firmwares of the FEET-ROC and the n-XYTER-ROC are also very similar in many of their tasks. Many parts of the firmware have already been developed and can be reused. This talk shall give a short overview which parts of the FEET-ROC are reused, which are new and how they are internally and externally connected. | |

| 1: Results from CBM-MPD STS Consortium activity in 2008 and work plan for 2009 are to be outlined. 2: Los Alamos version of the Dubna Quark Gluon String Model (LAQGSM) was coupled to the cbmroot framework to simulate transport of the Au-projectile Spectator Fragments (SF) emitted at angles close to zero degrees in collisions of gold ions at energies expected for experiments with CBM at SIS100 and SIS300. The profile of SF beam generated is shown to put severe constraints on the realistic pipeline of the CBM setup. The feasibility study was undertaken to reveal the power of SF tagging for estimation of the impact parameter and reaction plane in the collisions under inspection. | |

| Seddiki, Selim | Occupancy study of the Micro-Vertex Detector for the Compressed Baryonic Matter experiment |
| The Compressed Baryonic Matter experiment (CBM) is aiming at the study of dense and hot hadronic matter by means of relativistic heavy ion collisions. One important subsystem of CBM is the Micro-Vertex Detector (MVD) which is intended for detecting open charmed particles by reconstructing their displaced decay vertex. The MVD is located close to the collision point. We expect therefore very high occupancies and data rates due to the high multiplicitiy environment of the heavy ion collisions. In the work presented here we simulated the occupancy of the MVD. A focus was laid on the substantial amount of delta-electrons produced in the target of the experiment by the passage of beam particles. Their contribution to the detector occupancy has been investigated with GEANT3 and GCALOR for Au beam ions crossing the Au target material. Moreover, strategies to reduce the number of hits caused by those delta-electrons were evaluated. | |
