| TOAB01 | The New FAIR Accelerator Complex at GSI: Project, Controls Challenges, and First Steps | 59 |
|
||
| An international Facility for Antiproton and Ion Research (FAIR) was proposed by GSI in 2001 and is currently under development. This new accelerator complex will be a significant extension to the existing GSI accelerator chain and will provide a range of particle beams from protons and antiprotons to ion beams of all elements up to uranium, as well as secondary beams of short-lived rare isotope beams. The central parts of the FAIR facility are a superconducting double-ring synchrotron and a system of storage rings. This presentation covers the status and scope of the FAIR project and its technical and organizational challenges, in particular in respect to the accelerator control system. As many parts of the new FAIR facility will be independently developed as in-kind contributions by international FAIR partner institutes, one significant point is integration and interface management. Among many other aspects, one important technical consideration is a high degree of parallel beam operation for the different research programs that imposes ambitious demands on the timing and cycle management system. We will discuss first steps towards a new FAIR control system. | ||
| TOAB02 | Current Status of the Control System for J-PARC Accelerator Complex | 62 |
|
||
| J-PARC accelerator complex consists of a proton linac (LINAC), > a Rapid Cycle Synchrotron (RCS), and a Main Ring synchrotron (MR). The commissioning of LINAC already started in November 2006, while the commissioning of Main Ring synchrotron (MR) is scheduled in May 2008. Most of the machine components of MR have been installed in the tunnel. Introduction of electronic modules and wiring will be made by the end of 2007. For the control of MR, the J-PARC accelerator control network was extended to include the MR related parts in March 2007. IOC computers (VME-bus computers) for MR will be introduced in 2007. In addition, more server computers for application development will be also introduced in 2007. This paper reports the status of development for the J-PARC MR control system. | ||

| TOAB03 | ALICE Control System – Ready for LHC Operation | 65 |
|
||
| ALICE is one of the four LHC experiments presently being built at CERN and due to start operations by the end of 2007. The experiment is being built by a very large worldwide collaboration; about 1000 collaborators and 85 institutes are participating. The construction and operation of the experiment pose many technical and managerial problems, and this also applies to the design, implementation, and operation of the control system. The control system is technically challenging, representing a major increase in terms of size and complexity with respect to previous-generation systems, and the managerial issues are of prime importance due to the widely scattered contributions. This paper is intended to give an overview of the status of the control system. It will describe the overall structure and give some examples of chosen controls solutions, and it will highlight how technical and managerial challenges have been met. The paper will also describe how the various subsystems are integrated to form a coherent control system, and it will finally give some hints on the first experiences and an outlook of the forthcoming operation. | ||
| TOAB04 | The LIGO Detectors Controls | 68 |
|
||
| All three LIGO detectors have reached their design sensitivities. A sky-averaged detection range (SNR > 8) of more than 15 Mpc for inspiral binary neutron stars with masses of 1.4 Msol has been achieved with the two 4 km instruments. The fifth LIGO science started in November 2006 and more than 300 days of coincidence data has been collected so far. The feedback controls system is a major component to make LIGO work and its performance has been crucial to achieve the present sensitivity. | ||

| TOAB05 | The Status of Virgo | 71 |
|
||
|
Virgo is the largest gravitational wave detector in Europe. The detector, built by a French–Italian collaboration, is located near Pisa (Italy) and is based on a laser interferometer with 3-km-long arms. It aims at the detection of gravitational waves emitted by galactic and extragalactic sources such as pulsars, supernovae, and the coalescences of binary black holes and neutron stars in a frequency window comprised between 10 Hz and a few kHz. Since 2003 the detector has been going through its commissioning phase, and the first long observing run is planned to start in May 2007. The present status of the experiment and its foreseen upgrades are described in this article.
