Local control theory for superconducting qubits

In this work, we develop a method to design control pulses for fixed-frequency superconducting qubits coupled via tunable couplers based on local control theory, an approach commonly employed to steer chemical reactions. Local control theory provides an al ...

Method for estimating synchrophasors during static and dynamic conditions

Mario Paolone, Asja Derviskadic, Paolo Romano

A method for performing synchrophasor estimation of an input signal, whereby the input signal is a sinusoidal power system voltage or current signal, comprising: a. Periodic sampling of a continuous time-domain waveform, consisting of a power system voltag ...

An Analysis of Current and Electric Field Pulses Associated With Upward Negative Lightning Flashes Initiated from the Säntis Tower

Marcos Rubinstein, Mohammad Azadifar, Davide Pavanello, Lixia He

We present a study on the characteristics of current and electric field pulses associated with upward lightning flashes initiated from the instrumented Säntis Tower in Switzerland. The electric field was measured 15 km from the tower. Upward flashes always ...

High sensitivity field asymmetric ion mobility spectrometer

Jürgen Brugger, Giovanni Boero, Philippe Marmillod, Alessandro Valentino Matheoud, Mario Andres Chavarria Varon

A high sensitivity field asymmetric ion mobility spectrometer (FAIMS) was designed, fabricated, and tested. The main components of the system are a 10.6 eV UV photoionization source, an ion filter driven by a high voltage/high frequency n-MOS inverter circ ...

Novel Insight into the Output Current Ripple for Multilevel and Multiphase Converter Topologies

Drazen Dujic, Alexandre François Christe

When it comes to the computation / estimation of the switching losses in a multilevel converter, it is crucial to know the instantaneous value of the output current. If the average output current value is used instead, there is a non negligible error when ...

Definition of Accurate Reference Synchrophasors for Static and Dynamic Characterization of PMUs

Mario Paolone, Asja Derviskadic, Guglielmo Frigo, Marco Pignati, Daniele Colangelo

The calibration of phasor measurement units (PMUs) consists of comparing coordinated universal time time-aligned phasors (synchrophasors) measured by the PMU under test, against reference synchrophasors generated through a PMU calibrator. The IEEE Standard ...

Simple predictive electron transport models applied to sawtoothing plasmas

Olivier Sauter, Timothy Goodman, Antoine Pierre Emmanuel Alexis Merle, Doohyun Kim

In this work, we introduce two simple transport models to evaluate the time evolution of electron temperature and density profiles during sawtooth cycles (i.e. over a sawtooth period time-scale). Since the aim of these simulations is to estimate reliable p ...

Demonstration of sawtooth period control with EC waves in KSTAR

Olivier Sauter, Timothy Goodman, Doohyun Kim

The sawtooth period control in tokamak is important issue in recent years because the sawtooth crash can trigger TM/NTM instabilities and drive plasmas unstable. The control of sawtooth period by the modification of local current profile near the q=1 surfa ...
