MOAB01 The Status of the LHC Controls System Shortly Before Injection of Beam 5
  • P. Charrue, H. Schmickler
    CERN, Geneva
  At the time of the ICALEPCS 2007 conference, the LHC main accelerator will be close to its final state of installation, and major components will have passed the so-called “hardware commissioning.” In this paper the requirements and the main components of the LHC control system will be described very briefly. Out of its classical 3-tier architecture, those solutions will be presented, which correspond to major development work done here at CERN. Focus will be given to the present status of these developments and to lessons learned in the past months.

  Given the significant dangers of LHC operations, access control to the accelerator controls system is required. This paper describes the requirements, design, and implementation of Role-Based Access Control (RBAC) for the LHC and injectors controls systems. It is an overview of the two main components of RBAC: authentication and authorization, and the tools needed to manage access control data. We begin by stating the main requirements of RBAC and then describe the architecture and its implementation. RBAC is developed by LAFS a collaboration between CERN and Fermilab.  
RPPA35 The DIAMON Project – Monitoring and Diagnostics for the CERN Controls Infrastructure 588

  The CERN accelerators’ controls infrastructure spans over large geographical distances and accesses a big diversity of equipment. In order to ensure smooth beam operation, efficient monitoring and diagnostic tools are required by the operators, presenting the state of the infrastructure and offering guidance for the first line support. The DIAMON project intends to deploy software monitoring agents in the controls infrastructure, each agent running predefined local tests and sending its result to a central service. A highly configurable graphical interface will exploit these results and present the current state of the controls infrastructure. Diagnostic facilities to get further details on a problem and first aid to repair it will also be provided. This paper will describe the DIAMON project’s scope and objectives as well as the user requirements. Also presented will be the system architecture and the first operational version.
