| Alcocer | Marcelo | Computer Cluster monitoring with EPICS and SNMP | We present an implementation of the EPICS architecture with SNMP support to enable management of a cluster. Management information data is obtained from the MIBs of the cluster nodes using the telecom industry standard SNMP. This data is stored as records in EPICS, which due to its wide knowledge base and implementation, allows many possibilities for analysis and reaction. Remote access to these records is possible through the asychronous CA protocol, which is efficient and fast. One management possibilty is that network resources, hardware, and any other interfaced devices are controlled by EPICS to react to the data received from SNMP. Two alternative management options which we present are the remote display of the aquired SNMP data by the MEDM GUI, and the forwarding of the data to the SysMES management system for further analysis. |

| Bruder | Michael | Radiation Hard Design in UMC018 | The techniques to design radiation tolerant chips in deep submicron technologies are well known by now. It is not so easy in practice, however, to correctly implement designs with enclosed devices. The devices must be correctly modelled and the CAD tools must be modified to cope with the unusual shape. Digital cell libraries are usually not available and must therefore be designed with all information required for synthesis and automated place & route. The talk presents first results on a radiation hard mixed mode design flow in the UMC 0.18um technology. |
| Buzzetti | Siro | N-XYTER overview: a self-triggered detector-readout ASIC for high-rate time & amplitude measurement of randomly distributed events | We present the design of a 128-channel ASIC for readout of detectors delivering charge pulses. In order to handle signals that are randomly distributed in time and space, a completely self triggered architecture is implemented. Two parallel circuits per channel measure both the time of arrival and the amplitude of the input pulses. The ASIC will be able to acquire data at an overall rate of 30MHz with a time resolution of 2ns. An efficient de-randomizing scheme is adopted in order to channel the recorded random data into a synchronous output data bus. A first prototype containing the front-end circuits was manufactured in CMOS 0.35um technology. The test results of the prototype are presented. |

| Fröhlich | Ingo | MAPS pixel readout based on the HADES TRB concept | HADES has build a prototype for a standalone readout board which is used for the RPC detector. We present our ideas to use a similar concept for the readout of the monolitic active pixel sensors (MAPS). Prototypes of the MAPS chips have been designed by the IRES/Strassbourg and tested in a cooperation with the IKF-Frankfurt. Changes of the readout concept would allow system integration and online data analysis. |

| Lara | Camilo | System Management for distributed DCS | We present a decentralised management architecture for managing distributed DCS. The architecture is based on the Enterprise Java Beans technology using the JBoss Applications server in order to achieve a very good scalability and a high availability. Using a case example we will describe the functionality of our developed architecture. We will compare it to current controls systems in order to understand how our management architecture is able to complement current controls system and simplify the needed management tasks. One of the most important features is the possibility of managing configurations or system states in a decentralised and dynamic way. This enables the clients to obtain new or specific configurations or states, on the fly, from a local repository or server. Other appreciable characteristics are transaction-based communications which avoid information loss, and high availability using clustered services on the server side to prevent single points of failure. |
| Linev | Sergey | InfiniBand cluster for FutureDAQ | FAIR experiments like CBM require a new approach for the data acquisition system, since event tagging and selection will be done triggerless. Thus a most effective and fast data transport between many nodes is necessary. To evaluate possible techniques and performance, a small Linux cluster of CBM with InfiniBand (IB) connections is being tested at GSI. C++ software was implemented for IB data transport benchmarking, wrapping the uDAPL (User-level Direct Access Transport API Library). Here a data scheduling method using inter-node time synchronization was also developed. Investigations on the CMS XDAQ system have been started, as one example of a powerful DAQ framework |

| Malakhov | Alexander | Asymptotic regimes in relativistic nuclear and particle physics | A relativistic invariant description of multiple particle processes in relative 4-velocity space was suggested by A.M.Baldin. Following this approach relativistic invariant quantities b(ik) = - [u(i)-u(k)]**2 were introduced, where u(i) = p(i)/m(i), u(k) = p(k)/m(k) are 4-velocity particles i and k; p(i,k) and m(i,k) are their 4 momenta and masses. The distributions of the secondary particles in interaction of relativistic nuclei as functions of b(ik) have universal properties, which points to a common interaction mechanism of nuclei on the quark-gluon level. Experiments show that this regime is achieved for b(ik)~ 5 which corresponds to the kinetic energy of a nuclear beam of ~ 3.5 A GeV. It is possible to extend this approach on the hadrons. If we will observe asymptotic behaviour for example in cross-sections or the other characteristics of hadron interactions it is possible to interpret as manifestation of the internal structure of quarks. Such behaviour is really possible to observe in experiments. Such asymptotic regime is beginning with hadron momentum 50 GeV which is correspond b(ik) ~ 100. Thus we can propose that at b(ik) > 100 beginning manifestation of the internal structure of quarks and in this region possible to study internal structure of quarks at CBM setup. |
