Hydrodynamics of a Pump-Turbine Operating at Off-Design Conditions in Generating Mode

Modern pump-turbines are subject to frequent switching between the pumping and generating modes with extended operation under off-design conditions. Depending on the specific speed of the pump-turbine, the discharge-speed as well as torque-speed generating ...

Stability analysis of the Interconnection of the LHC Main Superconducting Bus Bars

Luca Bottura, Pier Paolo Granieri

The operation of the Large Hadron Collider calls for a thorough analysis of the thermo-electric behavior of the 13 kA superconducting bus-bars connecting its dipole and quadrupole main magnets. This presentation reports a synthesis of the work performed jo ...

Magnetic energy flows during the current quench and termination of disruptions with runaway current plateau formation in JET and implications for ITER

James Paley

The magnetic energy balance and magnetic energy flows for plasma disruptions in which runaway plateau plasmas are formed and terminated at JET has been analysed and compared with that of runaway-free disruptions. The analysis shows that the energy loss pro ...

Runaway electron energy measurement using hard x-ray spectroscopy in "Damavand" tokamak

Davoud Iraji

Set of experiments has been developed to study existing runaway electrons in "Damavand" tokamak plasma upon characteristics of hard x-ray emissions produced by collision of the runaway electrons with the plasma particles and limiters. As a first step, spat ...

Suppression of leakage currents in GaN-based LEDs induced by reactive-ion etching damages

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Julien Dorsaz, Antonino Francesco Castiglia, Mauro Mosca

Forward and reverse leakage currents in GaN/InGaN multi-quantum well light-emitting diodes (LEDs) are caused by reactive-ion etching (RIE) damages during device patterning. A method to recover the damaged surfaces, based on a chemical etch in KOH: ethylene ...

Multi-Processor Operating System Emulation Framework with Thermal Feedback for Systems-on-Chip

Giovanni De Micheli, David Atienza Alonso, Francisco Javier Rincon Vallejos, Luca Benini, Pablo Garcia del Valle

Multi-Processor System-On-Chip (MPSoC) can provide the performance levels required by high-end embedded applications. However, they do so at the price of an increasing power density, which may lead to thermal runaway if coupled with low-cost packaging and ...

Enhanced production of runaway electrons during a disruptive termination of discharges heated with lower hybrid power in the frascati tokamak upgrade

Francesca Maria Poli

We report on the observation of a large production of runaway electrons during a disruptive termination of discharges heated with lower-hybrid waves at the Frascati Tokamak Upgrade. The runaway current plateaus, which can carry up to 80% of the predisrupti ...

DC performances of ITER NbTi conductors: Models vs. measurements

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche

Within the R&D program on the International Thermonuclear Experimental Reactor (ITER) Poloidal Field (PF) coils, a full size conductor sample was tested in the SULTAN facility (CRPP Villigen, Switzerland). This sample is composed of two straight ITER-like ...
