Dependable Implementation of the Beam Interlock Mechanism in CERN Power Converter Controllers / Di Cosmo, Matteo (CERN) ; King, Quentin (CERN) ; Murillo-Garcia, Raul (CERN) ; Nisbet, David (CERN) ; Todd, Benjamin (CERN)
At CERN a Beam Interlock System (BIS) protects accelerators from accidental and uncontrolled release of beam energy, avoiding machine downtime. Throughout the accelerator complex numerous critical subsystems, including power converters, interact with the BIS indicating their readiness for operation with beam. [...]

Scintillation detectors based on silicon microfluidic channels / Maoddi, P (CERN ; Ecole Polytechnique, Lausanne) ; Mapelli, A (CERN) ; Bagiacchi, P (INFN, Rome) ; Gorini, B (CERN) ; Haguenauer, M (CERN) ; Lehmann Miotto, G (CERN) ; Murillo Garcia, R (CERN) ; Safai Tehrani, F (INFN, Rome) ; Veneziano, S (INFN, Rome) ; Renaud, P (Ecole Polytechnique, Lausanne)
Microfluidic channels obtained by SU-8 photolithography and filled with liquid scintillators were recently demonstrated to be an interesting technology for the implementation of novel particle detectors.The main advantages of this approach are the intrinsic radiationresistance resulting from the simple microfluidic circulation of theactive medium and the possibility to manufacture devices with highspatial resolution and low material budget using microfabricationtechniques.Here we explore a different technological implementation of thisconcept, reporting on scintillating detectors based on siliconmicrofluidic channels. A process for manufacturing microfluidicdevices on silicon substrates, featuring microchannel arrays suitablefor light guiding, was developed. [...]
