Intra-pin Reaction Rate Measurements in the CROCUS Experimental Reactor

Andreas Pautz, Vincent Pierre Lamirand, Mathieu Hursin, Oskari Ville Pakari, Thomas Jean-François Ligonnet, Tom Mager

In response to the need for validating high-fidelity deterministic neutronics solvers capable of providing pin-resolved neutron flux distributions, intra-pin reaction rates measurements were performed in the CROCUS experimental reactor. A specially designe ...

Tunability of space-time wave packet carrying tunable and dynamically changing OAM value

Tobias Kippenberg, Maxim Karpov

Space-time (ST) wave packets have gained much interest due to their dynamic optical properties. Such wave packets can be generated by synthesizing frequency comb lines, each having multiple complex-weighted spatial modes, to carry dynamically changing orbi ...

Uncontrolled manifold analysis of the effects of a perturbation-based training on the organization of leg joint variance in cerebellar ataxia

Silvestro Micera

Walking patterns of persons affected by cerebellar ataxia (CA) are characterized by wide stride-to-stride variability ascribable to: the background pathology-related sensory-motor noise; the motor redundancy, i.e., an excess of elemental degrees of freedom ...

Reconfigurable radiofrequency filters based on versatile soliton microcombs

Tobias Kippenberg, Camille Sophie Brès, Junqiu Liu, Maxim Karpov, Jijun He, Arslan Sajid Raja, Jianqi Hu, Anton Lukashchuk

The rapidly maturing integrated Kerr microcombs show significant potential for microwave photonics. Yet, state-of-the-art microcomb-based radiofrequency filters have required programmable pulse shapers, which inevitably increase the system cost, footprint, ...

Self-imaging of Azimuthal Intensity Petal Based on Orbital Angular Momentum Beams

Camille Sophie Brès, Jianqi Hu

We demonstrate for the first time azimuthal Talbot effect based on orbital angular momentum beams. The intensity petal is self-imaged in the azimuthal angle. We also draw the analogy between azimuthal and temporal Talbot effect. ...

Device for Determining a Bidirectional Reflectance Distribution Function of a Subject

Martin Vetterli, Loïc Arnaud Baboulaz

The present invention relates to a device (10) for determining a bidirectional reflectance distribution function of a subject (S) comprising: a light source (LS) for producing an incident light (li) and directing said incident light (li) onto a subject (S) ...

Grazing function g and collimation angular acceptance

Valentina Previtali

The grazing function g is introduced—a synchrobetatron optical quantity that is analogous (and closely connected) to the Twiss and dispersion functions β, α, η, and η′. It parametrizes the rate of change of total angle with respect to synchrotron amplitude ...
