Experimental indoors localization using distance measurements obtained from visual data

In recent years, the emergence of artificial intelligence increases the demand of automatic and robust localization outdoors and indoors. While GPS provides enough accuracy in most outdoor cases, there is still a lack of robust and efficient indoor localiz ...

Femtosecond pulse length and arrival time measurement of hard X-Ray FELs

Ishkhan Gorgisyan

The ultra-bright short-pulsed radiation provided by the free electron lasers (FEL) is used for many new discoveries in different fields of science and industry. The advancement of the FEL technologies allows the generation of shorter photon pulses with hig ...

Energy correlations of photon pairs generated by a silicon microring resonator probed by Stimulated Four Wave Mixing

Matteo Galli, Christophe Marcel Georges Galland, Davide Grassani

Compact silicon integrated devices, such as micro-ring resonators, have recently been demonstrated as efficient sources of quantum correlated photon pairs. The mass production of integrated devices demands the implementation of fast and reliable techniques ...

Pulsed light optical rangefinder

Edoardo Charbon, Cristiano Niclass

An optical rangefinder based on time-of-flight measurement, radiates pulsed light toward an object (70), and receives reflected light from the object, the receiver operating in a photon counting mode, so as to generate a pulse for a detected photon. There ...

Blob dynamics in the TORPEX experiment: a multi-code validation

Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Fabio Riva, Eric Serre

Three-dimensional and two-dimensional seeded blob simulations are performed with five different fluid models, all based on the drift-reduced Braginskii equations, and the numerical results are compared among themselves and validated against experimental me ...

Electrical resistance of single-crystal magnetite (Fe3O4) under quasi-hydrostatic pressures up to 100GPa

Helmuth Berger

The pressure dependence of electrical resistance of single-crystal magnetite (Fe3O4) was measured under quasi-hydrostatic conditions to 100 GPa using low-temperature, megabar diamond-anvil cell techniques in order to gain insight into the anomalous behavio ...

Thermal Boundary Conductance: A Materials Science Perspective

Christian Monachon, Ludger Weber

The thermal boundary conductance (TBC) of materials pairs in atomically intimate contact is reviewed as a practical guide for materials scientists. First, analytical and computational models of TBC are reviewed. Five measurement methods are then compared i ...

Development of the ITER Continuous External Rogowski: From conceptual design to final design

Duccio Testa, Christian Schlatter, Matthieu Toussaint, Jonathan Bryan Lister, Philippe Marmillod

In ITER, an accurate measurement of plasma current, with high reliability, is mandatory as this parameter is used to demonstrate licensing compliance with regulatory limits. For that purpose, several independent measurements based on magnetic diagnostics h ...

Laser arrival measurement tools for SwissFEL

Christoph Peter Hauri

SwissFEL is aiming to produce X-ray pulses from 30 fs down to the attosecond time scale. This requires the compression of the several picosecond long electron bunches produced by a photo-injector to sub-fs level. To achieve this, 40fs accurate injection of ...

Design and Measurement Methodology for a Sub-picoampere Current Digitiser

Maher Kayal, Evgenia Voulgari, François Krummenacher

This paper introduces some design and measurement techniques that were used in the design and the testing of an ASIC for ultra-low current sensing. The idea behind this paper is to present the limitations in sub-picoampere current measurements and demonstr ...
