Power Distribution Solutions for Large Hadron Collider Upgrades

Stefano Michelis

In view of the Large Hadrons Collider experiments upgrade, where the inner front-end electronics will require higher supply power, a new power distribution scheme has to be designed. This thesis presents a new and more efficient scheme based on step-down D ...

Optimizing Data-Center TCO with Scale-Out Processors

Babak Falsafi, Boris Robert Grot, Pejman Lotfi Kamran

Performance and total cost of ownership (TCO) are key optimization metrics in large-scale data centers. According to these metrics, data centers designed with conventional server processors are inefficient. Recently introduced processors based on low-power ...

EM SIMULATIONS IN BEAM COUPLING IMPEDANCE STUDIES: SOME EXAMPLES OF APPLICATION

Carlo Zannini, Giovanni Rumolo

In the frame of the SPS upgrade an accurate impedance model is needed in order to predict the instability threshold and if necessary to start a campaign of impedance reduction. Analytical models, 3-D simulations and bench measurements are used to estimate ...

Capturing EELS in the reciprocal space

Cécile Hébert, Audrius Alkauskas

In this work two aspects of momentum-dependent electron energy loss spectrometry are studied, both in the core-loss and in the low-loss region. In the case of core losses, we focus on the demonstration and the interpretation of an unexpected non-Lorentzian ...

Design, Optimization, and Sensorless Control of a Linear Actuator

Joël Maridor

Electrical contactors are relays for interputing high currents (up to 2000 A). They consist of three main distinct parts: the low voltage circuit, the high voltage circuit and the linear actuator that moves the contact. The purpose of this thesis is to des ...

Optimization of Shielded PCB Air-Core Toroids for High-Efficiency DC-DC Converters

Maher Kayal, Stefano Michelis, Federico Faccio

The paper describes the design of optimized printed circuit board (PCB) air-core toroids for high-frequency dc-dc converters with strict requirements in terms of volume and noise. The effect of several design parameters on the overall inductor volume, on d ...

A Hybrid Mapping-Scheduling Technique for Dynamically Reconfigurable Hardware

David Atienza Alonso, Ivan Beretta

Reconfigurable computing is a promising technology that offers an interesting trade-off between flexibility and performance, which many recent multi-core embedded system applications demand. In order to achieve these objectives, it is necessary to optimize ...

QUADRUPOLAR TRANSVERSE IMPEDANCE OF SIMPLE MODELS OF KICKERS

Nicolas Frank Mounet, Carlo Zannini, Benoît Salvant

The SPS kickers are major contributors to the SPS transverse beam coupling impedance. The current ”flat chamber” impedance model for a kicker is obtained by applying form factors to the theoretical impedance of an axisymmetric ferrite beam pipe. This model ...

Eddy current power losses in a toroidal laminated core with rectangular cross section

Yves Perriard, Miroslav Markovic

The paper presents a completely analytical solution for the magnetic field, the induced eddy currents and corresponding losses in a toroidal laminated core with a rectangular cross section. The diffusion equation is analytically solved using a separation o ...
