The detector must be able to reject back- ground events from decay channels which branching fractions are up to 10 order of magnitude higher than the signal and with similar experimental signature. To suppress the main background from K+ -> mu+ nu decay (BR ~ 63%), NA62 will rely on a gas based RICH detector for pion/muon separation in a momentum range between 15 and 35 GeV/c with a muon rejection factor better than 5x10-3. The RICH detector will be used as Level 0(LO) trigger and event time measurement with a resolution better than 100ps to minimize wrong matching with the mother particle mea- sured by an upstream detector. To provide such a very demanding task a RICH detector filled with Neon at atmospheric pressure, 18 m long and equipped with 2000 photomultipliers has been proposed. The details of the RICH project will be described. A RICH prototype of the same length of the final detector, equipped with 96 PMs has been built and tested on a pion beam at CERN in the 2007 fall. A second prototype of a full length Neon filled vessel equipped with a spherical mirror and 414 PMs in the focal planewas built and tested in 2009 at CERN SPS on a positive hadron beam. The results of the two test beams will be presented: the muon misidentification probability is found to be about 0.7% and the time resolution better than 100 ps in the whole momentum range. Preliminary results on testbeam data and Montecarlo comparison for runs collected with CO2 and Oxygen polluted Neon will be also presented.

The performance of these detectors requires uniform response across the surface of the scintillator. Flat and shaped scintillator tiles directly coupled to silicon photo-multipliers have been investigated with both a radioactive source and high energy protons. We present results which indicate that, as expected, flat cells have high re- sponse near the photo-sensors while shaped cells have a much more uniform response, suggesting cells can be tailored to ensure uniform response. We also present results demonstrating that the response of the cells to a source and to beam particles are in qualitative agreement. Investiga- tions into fully integrated electronics and directly coupled scintillators and photo-sensor readout modules are reported.

One of the goals of the CMD 3 experiment (BINP, Russia) is a study of the hadron production in electron-positron annihilation. An important example of such process is a neutron-antineutron pair production near threshold. A signature of this process is a large energy deposition in the liquid xenon (LXe) calorimeter due to antineutron annihilation which typically occurs by 5 ns or later after beams collision. For identification of such events and for providing a trigger bythemit is necessary to determine the time of signal appearance with accuracy of 2-3 ns On-Line. The LXe- calorimeter of the CMD-3 consists of 14 coaxial cylindrical ionization chambers with anode and cathode readout. The duration of the charge collection to the anodes is about 4.5 microseconds. Thus, to obtain the required accuracy of the On-Line measurements of the signal arrival timea special signal processing method has been developed. In this paper the signal processing algorithm and a selection of the optimal parameters of the measuring channel are described.

For an experiment like PANDA, the trigger and data acquisition system needs to handle interaction rates of the order of more than 10^7/s and data rates of 200 GB/s and more. The high level trigger and data processing with high performance is necessary. An ATCA compliant FPGA-based Compute Nodes system is designed for this purpose. Each CN features 5 Xilinx Virtex-4 FX60 FPGA chips and up to 10GB DDR2 memory. A total bandwidth of 52Gbps optical links (8ch x 6.5Gbps/ch) and 39Gbps electrical backplane links (13ch x 3Gbps/ch) are provided to receive data from front-end electronics and data transmission among different channels. The high data processing performance are accomplished by the fabric resources provided by 5 FPGA chips. 5 Gigabit Ethernet links are used to transmit processing results to mass storage. The finished version has been proved successful and is being used in trigger and DAQ development for PANDA system, and also under investigation for use in PXD in Belle II. The ATCA-based Trigger and Data Acquisition System is scalable and suitable for various applications for next-generation nuclear and particle experimental physics.

Therefore it is required to handle with the monitoring information which is also distributed in the LANs. We developed a new software framework for online monitoring, which collects distributed information and achieves easy access to the information far from DAQ systems via internet. The framework consists of three parts, DAQ- subsystems, “Monitor server” and “Monitor viewer”. Each DAQ-subsystem converts the monitored information to histograms and handles with them as an object named “Histogram package”, a collection of histograms. Monitor server collects and transfers the histogram packages to the view- ers. Monitor Viewers creates graphical plots on their GUI windows. We also developed two types of viewers. One is a java application, which can achieve real time monitoring by connecting with Monitor server directly. The other is a web application works on web browsers with Ajaxand HTML5 technologies. GUIs of each viewer are generated automatically by XML based configura- tion files and therefore DAQ developers can create viewer plots with modifying the viewers. We will present the detail structure of the online monitor framework with some application examples of the Double Chooz reactor neutrino experiment.

We will place two identical detectors to accomplish the systematic-free measurement of the neutrino disappear- ance. Each detector has 468 PMTs which will detect scintillation light generated by neutrino or background events. And nominal High voltage values are defined so that every PMT have 10^7 gain. High voltage system is very important in the experiment, since the PMT gain should be affected by the high voltage directly. In Double Chooz, we adopted the HV crate SY1527LC and the module A1535P produced by CAEN, and developed the online system for both control and monitoring.
