A search engine for the engineering and equipment data management system (EDMS) at CERN / Tsyganov, A (CERN) ; Amérigo, S M (CERN) ; Petit, S (CERN) ; Pettersson, Thomas Sven (CERN) ; Suwalska, A (CERN)
CERN, the European Laboratory for Particle Physics, located in Geneva -Switzerland, is currently building the LHC (Large Hadron Collider), a 27 km particle accelerator. The equipment life-cycle management of this project is provided by the Engineering and Equipment Data Management System (EDMS [1] [2]) Service. [...]

Scheduling the powering tests / Barbero-Soto, E (CERN) ; Bellesia, B (CERN) ; Casas-Lino, M P (CERN) ; Fernandez-Robles, C (CERN) ; Foraz, K (CERN) ; Pojer, M (CERN) ; Saban, R (CERN) ; Schmidt, R (CERN) ; Solfaroli-Camillocci, M (CERN) ; Vergara-Fernandez, A (CERN)
The Large Hadron Collider is now entering in its final phase before receiving beam, and the activities at CERN between 2007 and 2008 have shifted from installation work to the commissioning of the technical systems ("hardware commissioning"). Due to the unprecedented complexity of this machine, all the systems are or will be tested as far as possible before the cool-down starts. [...]

Collimateur integration and installation : Example of one object to be installed in the LHC / Aberle, O (CERN) ; Assmann, Ralph Wolfgang (CERN) ; Chamizo, R (CERN) ; Weiler, T (CERN) ; Chemli, S (CERN) ; Corso, J P (CERN) ; Coupard, J (CERN) ; Delsaux, F (CERN) ; Foraz, K (CERN) ; Jiménez, J M (CERN) et al.
The collimation system is a vital part of the LHC project, protecting the accelerator against unavoidable regular and irregular beam loss. About 80 collimators will be installed in the machine before the first run. [...]

Integration of CATIA/Smarteam into CERN's corporate engineering data management system / Hakulinen, Timo (CERN) ; Delamare, Christophe (CERN) ; Friman, Per Olof (CERN) ; Pettersson, Thomas Sven (CERN) ; Van Uytvinck, E (CERN) ; Widegren, David (CERN) ; Fournier, G (SPI Numérique, Lyon)
We present a short overview of the strategy defined to integrate the 3D CAD system CATIA/Smarteam into CERN's corporate Engineering and Equipment Data Management System (EDMS), which is used to manage the information about the Laboratory's installations and technical infrastructure. A brief description of the existing EDMS architecture is given, describing the available project life cycle management features, including CATIA/Smarteam. [...]

The CERN Engineering and Equipment Data Management System (EDMS) is one of the largest and most complex data management systems of its kind. For the last 10 years, it has received huge quantities of data generated in the different LHC project phases. [...]

Safety testing for LHC access system / Valentini, F (CERN) ; Ladzinski, T (CERN) ; Ninin, P (CERN) ; Scibile, S (CERN)
In the domain of Safety Real-Time Systems the problem of testing represents always a big effort in terms of time, costs and efficiency to guarantee an adequate coverage degree. Exhaustive tests may, in fact, not be practicable for large and distributed systems. [...]

Coordination of the commissioning of the LHC technical systems / Saban, R (CERN) ; Bellesia, B (CERN) ; Casas Lino, M P (CERN) ; Fernandez Robles, C (CERN) ; Pojer, M (CERN) ; Schmidt, R (CERN) ; Solfaroli Camillocci, M (CERN) ; Vergara Fernandez, A (CERN)
The Large Hadron Collider operation relies on 1232 superconducting dipoles with a field of 8.33T and 400 superconducting quadrupoles with a strength of 220 T/m powered at 12kA, operating in superfluid He at 1.9K. For dipoles and quadrupoles as well as for many other magnets more than 1700 power converters are necessary to feed the superconducting circuits. [...]

RFQ Vacuum brazing at CERN / Mathot, S (CERN)
The aim of this paper is to describe the vacuum brazing procedure used at CERN for the brazing of Radio Frequency Quadrupole (RFQ). The RFQ is made of high precision machined OFE copper pieces assembled together. [...]

Modeling of the RF-shield Sliding Contact Fingers for the LHC Cryogenic Beam Vacuum Interconnects Using Implicit and Explicit Finite Element Formulations / Ramos, D (CERN)
The short interconnect length between the LHC superconducting magnets required the development of an optimised RF shielded bellows module, with a low impedance combined with compensation for large thermal displacements and alignment lateral offsets. Each bellows is shielded by slender copper-beryllium fingers working as preloaded beams in order to provide a constant force at the sliding contact. [...]
