A New High-intensity Proton Irradiation Facility at the CERN PS East Area / Gkotse, B (CERN) ; Glaser, M (CERN) ; Lima, P (CERN) ; Matli, E (CERN) ; Moll, M (CERN) ; Ravotti, F (CERN)
The proton and mixed-field irradiation facilities in the CERN PS East Area (known as IRRAD1 and IRRAD2), were heavily and successfully used for irradiation of particle detectors, electronic components and materials since 1992. These facilities operated with particle bursts - protons with momentum of 24GeV/c - delivered from the PS accelerator in “spills” of about 400ms (slow extraction). [...]

Bake-Out Mobile Controls for Large Vacuum Systems / Blanchard, S (CERN, Switzerland) ; Bellorini, F (CERN, Switzerland) ; Gomes, P (CERN, Switzerland) ; Pereira, H (CERN, Switzerland) ; Kopylov, L (IHEP, Protvino, Russia) ; Merker, S (IHEP, Protvino, Russia) ; Mikheev, M (IHEP, Protvino, Russia)
Large vacuum systems at CERN (Large Hadron Collider - LHC, Low Energy Ion Rings - LEIR...) require bake-out to achieve ultra-high vacuum specifications. The bake-out cycle is used to decrease the outgassing rate of the vacuum vessel and to activate the Non-Evaporable Getter (NEG) thin film [...]

The Control System of CERN Accelerators Vacuum (LS1 Activities and New Developments) / Gomes, P (CERN, Switzerland) ; Antoniotti, F (CERN, Switzerland) ; Bellorini, F (CERN, Switzerland) ; Blanchard, S (CERN, Switzerland) ; Boivin, JP (CERN, Switzerland) ; Gama, J (CERN, Switzerland) ; Girardot, G (CERN, Switzerland) ; Pigny, G (CERN, Switzerland) ; Rio, B (CERN, Switzerland) ; Vestergard, H (CERN, Switzerland) et al.
After 3 years of operation, the LHC entered its first Long Shutdown period (LS1), in February 2013 [1]. Major consolidation and maintenance works are being performed across the whole CERN’s Accelerator chain, in order to prepare the LHC to restart at higher energy, in 2015. [...]

Quality Management of CERN Vacuum Controls / Antoniotti, F (CERN, Switzerland) ; Boivin, JP (CERN, Switzerland) ; Fortescue-Beck, E (CERN, Switzerland) ; Gama, J (CERN, Switzerland) ; Gomes, P (CERN, Switzerland) ; Le Roux, P (CERN, Switzerland) ; Pereira, H (CERN, Switzerland) ; Pigny, G (CERN, Switzerland)
The vacuum controls Section (TE-VSC-ICM) is in charge of the monitoring, maintenance and consolidation of the control systems of all accelerators and detectors in CERN; this represents 6 000 instruments distributed along 128 km of vacuum chambers, often of heterogeneous architectures and of diverse technical generations. In order to improve the efficiency of the services provided by ICM, to vacuum experts and to accelerator operators, a Quality Management Plan is being put into place. [...]

Developments on the SCADA of CERN Accelerators Vacuum / Antoniotti, F (CERN, Switzerland) ; Blanchard, S (CERN, Switzerland) ; Boccioli, M (CERN, Switzerland) ; Gomes, P (CERN, Switzerland) ; Pereira, H (CERN, Switzerland) ; Kopylov, L (IHEP, Protvino, Russia) ; Mikheev, M (IHEP, Protvino, Russia) ; Merker, S (IHEP, Protvino, Russia)
During the first 3 years of LHC operation, the priority for the SCADA (Supervisory Control And Data Acquisition) of vacuum controls was to attend to user requests, and to improve its ergonomics and efficiency: access & presentation of information simplified and normalized; coherent functionalities & menus across all accelerators; automatic scripts instead of fastidious manual actions; enhanced tools for data analysis and for maintenance interventions. Several decades of cumulative developments, based on heterogeneous technologies and architectures, have been asking for a homogenization effort. [...]

A Fuzzy-Oriented Solution for Automatic Distribution of Limited Resources According to Priority Lists / Pezzetti, M (CERN, Switzerland) ; Inglese, V (CERN, Switzerland) ; Tovar-Gonzalez, A (CERN, Switzerland) ; Coppier, H (ESIEE, Amiens, France) ; Almeida, M (UFMG, Belo Horizonte, Brazil)
This project provides a solution for problems in which there is a limited cryogen resource that supplies several clients in parallel, which can cause the resource’s depletion. This study emerged from the need to solve a specific problem of the Cryogenics Group of the European Organization for Nuclear Research (CERN). [...]

Validation of the Data Consolidation in Layout Database for the LHC Tunnel Cryogenics Controls Upgrade / Tovar-Gonzalez, A (CERN, Switzerland) ; Balle, C (CERN, Switzerland) ; Blanco, E (CERN, Switzerland) ; Fortescue-Beck, E (CERN, Switzerland) ; Fluder, C (CERN, Switzerland) ; Inglese, V (CERN, Switzerland) ; Pezzetti, M (CERN, Switzerland) ; Gomes, P (CERN, Switzerland) ; Wolak, T (CERN, Switzerland) ; Dudek, M (CERN, Switzerland) et al.
The control system of the Large Hadron Collider cryogenics manages over 34’000 instrumentation and actuator channels. The complete information on their characteristics and parameters can be extracted from a set of views on the Layout database, to generate the specifications of the control system; from these, the code to populate PLCs (Programmable Logic Controller) and SCADA (Supervisory Control & Data Acquisition) is automatically produced, within the UNICOS framework (Unified Industrial Control System).
