20. LOGISTICS OF LHC CRYODIPOLES: FROM SIMULATION TO STORAGE MANAGEMENT

Foraz, K. , Nicquevert, B.

04/05/2004, 14:10

The main families of LHC superconducting cryomagnets consist of approximately 1240 cryodipoles and 480 Short Straight Sections (SSS). The different contracts, which are constraining the production and installation of these cryomagnets, have been initially rated according to the baseline schedule, based on a "just in time" scheme. However the complexity of the construction and the time required...

21. MECHANICAL DYNAMIC LOAD OF THE LHC ARC CRYO-MAGNETS DURING THE INSTALLATION

Artoos, K. , Capatina, O.

04/05/2004, 14:30

About 1700 LHC main superconducting dipoles and quadrupoles will have to be transported and handled between the assembly, the magnet measurements and the storage that precedes the final installation in the LHC tunnel. To ensure the required mechanic and geometric integrity of the cryo-magnets, transport specifications and allowed acceleration loads were defined after detailed dynamic analysis....

22. SECURITE DES OPERATIONS DE TRANSPORT - MANUTENTION

Prodon, S.

04/05/2004, 14:50

Dans le cadre de la démarche sécurité au sein du groupe TS-IC, ce document décrit les mesures mises en œuvre afin de rationaliser l’organisation sécurité des opérations de transport – manutention. Le papier s’attachera tout d’abord à clarifier les responsabilités des différents intervenants au cours de chaque phase (préparation, planification, coordination, supervision). La stratégie envisagée...

23. SPS EXTRACTION KICKER MAGNET - THERMAL ANALYSIS

Timmins, M.

04/05/2004, 15:10

As the SPS accelerator will be used for the CNGS project and as LHC injector, the proton beams passing through its extraction kickers will have a much higher intensity than in the past. The image currents generated by this beam may provoke a temperature increase in the magnet’s ferrite core to temperatures above the Curie temperature, unless the heat produced is effectively removed. A further...

24. BOITES DE DISTRIBUTION POUR L’ALIMENTATION ELECTRIQUE DU LHC

Folch, R., Trilhe, P.

04/05/2004, 15:30

En tant qu’unité d’engineering mécanique et matériaux, le groupe MME est en charge de la conception et des dossiers de spécification des DFBA, DFBL & DFBM (Electrical Distribution Feed Boxes) du LHC. Ces équipements complexes ont pour fonction principale l’alimentation électrique de puissance des aimants de la machine. Au total 34 types de DFB différents seront nécessaires, comportant quelque...

26. THE LHC COLLIMATORS

Bertarelli, A.

04/05/2004, 16:10

In the framework of the LHC Collimator project, TS department has been assigned the task to design the series collimators and to manufacture prototypes to be tested in summer 2004. Their concept must comply with a very demanding specification, entailing a temperature on the collimating jaws not exceeding 50ºC in steady conditions and an unparalleled overall geometrical stability of 25 m on a...

27. INTEGRATION OF TRANSPORT AND HANDLING EQUIPMENT AT CERN – CRITERIA TO SATISFY OPERATIONAL NEEDS AND SAFETY ASPECTS

Bertone,C. , Boettcher, O.

04/05/2004, 16:30

Within the last 4 years TS-IC-HM (former ST-HM group) integrated about 150 transport and handling supplies including 29 cranes, 20 fork lift trucks, 60 tunnel vehicles. Most of these are standardised supplies, but very often special functionality has been implemented and the complexity of the equipment has been increased. With the Rocla cryo-dipol transporters even prototype equipment was...

16. LHC ACCESS SYSTEM: STATUS REPORT

Ninin, P.

04/05/2004, 16:50

The LHC complex is divided into a number of areas with different levels of access authorizations. The LHC interlocked areas are the ones where access is restricted, and not allowed during beam operation or equipment tests. Inside those interlocked areas, the personnel protection is ensured by the LHC Access System. This system is made of two parts: the LHC Access Control System and the LHC...

17. IMPROVING INDUSTRIAL PROCESS CONTROL SYSTEMS SECURITY

Epting, U., Morodo, MC.

04/05/2004, 17:10

System providers are today creating process control systems based on remote connectivity using internet technology, effectively exposing these systems to the same threats as corporate computers. It is becoming increasingly difficult and costly to patch/maintain the technical infrastructure monitoring and control systems to remove these vulnerabilities. A strategy including risk assessment,...

18. TIM (TECHNICAL INFRASTRUCTURE MONITORING) AND CCC

Batz, M., Sollander, P.

04/05/2004, 17:30

The Technical Infrastructure Monitoring project (TIM) will implement the future control system for the TCR. The aim of the project is to replace the current TCR monitoring system with a modern system built on standard hardware and software components, taking advantage of existing services and license agreements. The TIM system will be put in operation in the TCR towards the end of 2004, but is...
