WEZG01 Protection Controls for High Power Accelerators 1921

  The next generation hadron accelerators will operate with MW beams or store beams with an energy of many 100 MJ. Machine protection will constrain operation, but some operational flexibility is still required for commissioning and performance optimization. This is a substantial challenge for control systems and application programs. New tools are developed to face those challenges: critical settings management, software interlocks, role based access to equipment, automatic accelerator mode recognition etc. This talk presents some of the challenges and tools. Experience with novel approaches are discussed.

WEZG02 Commissioning of an Accelerator: Tools and Management 1926
 
  • A. Nadji

  During the life of an accelerator project, the commissioning is a very important and exciting phase. It is preceded by a long period of design, calculations, magnetic measurements, installation, and alignment. We want the commissioning stage to be successful and fast; that is, attaining rapidly the set goals and make the machine available for impatient users. This paper summarizes the experience of several commissioning phases for different types of accelerators such as SNS, JPARC, and LHC, as well as synchrotron light sources such as DIAMOND, SOLEIL, and SSRF. The importance of preparation for commissioning on both technical and personnel levels will be covered. We will also talk about the concept of stages, anticipation of problems, and the early involvement of many specialists in addition to accelerator physicists and future accelerator operators. Furthermore, we will outline the importance of having a command control that is practical, fast, and has the capacity to offer high level automated applications. Finally, we will discuss the indispensable role of diagnostics for the first injection and first turns of the beam.
