Each microstrip and ASIC channel delivers position information, a fast time stamp of 2 ns resolution and the signal amplitude. The time stamp T is used for correlating the signals from the X and Y strips with low chance coincidence rate while the amplitude E is used for finding the center of gravity of a cluster of strips. The T and E information are stored in derandomizing buffers and read out via a token ring architecture.","PeriodicalId":217483,"journal":{"name":"2007 15th IEEE-NPSS Real-Time Conference","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127629323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two motivators for adopting the PXI platform are the high-speed PCI data communication bus and integrated timing and triggering features. Now, as the commercial PC industry improves bus bandwidth by evolving PCI to PCI express, PXI has evolved by integrating PCI express into the PXI standard to create PXI express. This paper gives an overview of the PXI platform including the data bus and timing and triggering features of PXI and PXI express.","PeriodicalId":217483,"journal":{"name":"2007 15th IEEE-NPSS Real-Time Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134214979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While designing detector systems adequate for these conditions represents a challenge in itself, their safe operation relies heavily on fast, radiation-hard beam condition monitoring (BCM) systems to protect these expensive devices from beam accidents. The talk will present such a BCM system based on polycrystalline chemical vapor deposition (pCVD) diamond sensors designed for the Collider Detector at Fermilab (CDF) experiment operating at Fermilab's Tevatron proton-antiproton synchrotron. We report our operational experience with this system, which was commissioned in the spring of last year. The system currently represents the largest of its kind to be operated at a hadron collider. It is similar to designs being pursued by the next generation of hadron collider experiments at the Large Hadron Collider (LHC).","PeriodicalId":217483,"journal":{"name":"2007 15th IEEE-NPSS Real-Time Conference","volume":"11 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128526270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The full set of final readout electronics boards was employed, together with the pre-series version of the data acquisition software.

This paper presents the overall design of RBAC implementation in the ATLAS experiment and the enforcement solutions in different areas such as the system administration, control room desktops and the data acquisition software.

The increase of resource is primarily the result of technology progress while the efficient use of the resources is the responsibility of the users. In this document, a variety of examples of the FPGA application in the high-energy physics and accelerator instrumentation will be discussed with emphasis on resource awareness issues. For the FPGA/reconfigurable computing, rich experiences can be transplanted from micro-processor counterpart. While on the other hand FPGA specific issues should be dealt with differently. Several principles in both aspects will be summarized. Topics of this document include: (1) Recognizing FPGA and microcomputer resources, similarities and differences.

Section I gives a brief overview of the process manager functionalities. Section II focuses on the requirements the process manager system has to fulfil to be fully integrated in the DAQ system. Section III shows how the requirements are met by the current implementation. The communication schema between the different parts of the process manager system, the procedure to launch a process and the possible states in which a process can be are described in Sections IV, V and VI.
