New Beam Permit Process for the Proton Synchrotron Complex

Raul Valera Teruel, F. Chapuis, Jose-Luis Duran-Lopez, Christelle Gaignant et autres

Injecting beams in CERN facilities is subject to the CERN safety rules. It is for this reason that the Beam Permit approval procedure was improved by moving away from a paper-based workflow to a digital form. For each facility the Beam Permits …

TREC: Traceability of Radioactive Equipment at CERN

Maciej P Kepinski, P. Martel, Tim Schmittler, Marc Tavlet et autres

Activated accelerator components are frequently removed from service due to changes in design, configuration or maintenance work. Safe and effective management of such components is a necessity. Moreover, local authorities require the tracking of this equipment: any piece of equipment or waste …

ON-LINE RADIATION TEST FACILITY FOR INDUSTRIAL EQUIPMENT NEEDED FOR THE LARGE HADRON COLLIDER AT CERN

Raymond Rausch, Marc Tavlet

The future Large Hadron Collider to be built at CERN will use superconducting magnets cooled down to 1.2 K. To preserve the superconductivity, the energy deposition dose levels in equipment located outside the cryostat, in the LHC tunnel, are calculated to be …

High-level dosimetry results for the CERN high-energy accelerators : part 3: the LEP machine (at 94.5 GeV) 1998

A. Fontaine, Marc Tavlet

This year, for the second time, the high-level dosimetry results are presented in three separate reports : Part 1 gives the doses in the PS complex, Part 2 in the SPS complex.This Part 3 gives the doses in the LEP machine.The results …

High-level dosimetry results for the CERN high-energy accelerators : part 2: SPS complex 1998

A. Fontaine, Marc Tavlet

This year, the high-level dosimetry results are presented in three separate reports: Part one concerns the doses in the machines of the PS complex, this one concerns the doses in the SPS and Part 3, the doses in the LEP complex.The results …

Radiation test programme on COTS components needed for the Large Hadron Collider at CERN

R. Rausch, Marc Tavlet

Beam monitors using cameras have evolved from qualitative beam observation to precision measurements. After a description of the two main TV standards, the various sensors: TV tubes (Vidicon), solid state sensors (Interline and Frame Transfer CCDs, CMOS and CID X-Y matrices), and …

Synchrotron Radiation Effects at LEP

Roger L. Bailey, G. von Holtey, N. Hilleret, C. Bovet et autres

With the increase of the LEP beam energy, synchrotron radiation effects become ever more important. Around the experiments, masks have been successfully used to absorb the higher rates, and photon bac kgrounds have not been a problem. Elsewhere around the ring, however, …

Compilation of radiation damage test data, pt.2

H. Schönbacher, A. Fontaine, Marc Tavlet

Investigations into the degradation of materials and components which are exposed to ionizing radiation have been carried out in many applications, such as nuclear reactors, fusion reactors, high-energy accelerators, medical and industrial irradiation facilities, space projects, etc.At the European Organization for Nuclear …

Effets des radiations sur les matériaux polymériques utilisés dans les accélérateurs de particules du CERN

Marc Tavlet

Pour la recherche fondamentale sur la structure intime de la matière, l’Organisation Européenne pour la Recherche Nucléaire (CERN) exploite des accélérateurs de particules à haute énergie autour desquels les matériaux et les composants sont exposés aux radiations ionisantes. Afin d’assurer une exploitation …
