Particle-Shadow Tracking – Combining Magnetic Particle Manipulation with In-Situ Optical Detection in a CMOS Microsystem

Edoardo Charbon, Ulrike Lehmann, Cristiano Niclass, Stefano Pietrocola

We present a hybrid CMOS based microsystem where magnetic actuation of microparticles is combined with integrated optical detection via Single Photon Avalanche Diodes (SPADs). The system’s configuration permits the manipulation and detection of single magn ...

Optical interactions in a plasmonic particle coupled to a metallic film

Olivier Martin

The interplay between localized surface plasmon (LSP) and surface plasmon-polariton (SPP) is studied in detail in a system composed of a three-dimensional gold particle located at a short distance from a gold thin film. Important frequency shifts of the LS ...

Influence of particle sources on electron density peaking in TCV and JET

Alexander Karpushov, Henri Weisen

Calculations of the particle flux caused by neutrals originating from the edge are performed for TCV and JET using the one-dimensional kinetic transport code Kn1D. The analysis, confirmed by experimental evidence, shows that for TCV and JET edge fuelling a ...

Aggregation and Charging of Colloidal Silica Particles: Effect of Particle Size

Paul Bowen, Michal Borkovec, Frédéric Juillerat

We studied systematically aqueous suspensions of amorphous well-characterized silica particles by potentiometric titration, electrophoretic mobility, and time-resolved light scattering. Their charging behavior and aggregation rate constants were measured a ...

Beam-cavity interactions in high power cyclotrons

Lukas Stingelin

The ring cyclotron of the Paul Scherrer Institute (PSI) accelerates an intense proton beam from 72MeV up to 590MeV. This happens in four cavities of very high quality factor, oscillating in the fundamental mode. The beam can excite parasitic oscillation mo ...

Homogenization method for transport of DNA particles in heterogeneous arrays

Assyr Abdulle

In this paper we study the large scale transport of the DNA particles through a heterogeneous micro array in the framework of homogenization theory. We derive the macro scale particle transport equation and show that for transport of particles in a diverge ...

Aspects of two dimensional magnetic Schrödinger operatorsquantum hall systems and magnetic Stark resonances

Christian Ferrari

In this PhD thesis we deal with two mathematical problems arising from quantum mechanics. We consider a spinless non relativistic quantum particle whose configuration space is a two dimensional surface S. We also suppose that the particle feels the effect ...
