Nanostenciling for fabrication and interconnection of nanopatterns and microelectrodes

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Sébastien Gauthier

Stencil lithography is used for patterning and connecting nanostructures with metallic microelectrodes in ultrahigh vacuum. Microelectrodes are fabricated by static stencil deposition through a thin silicon nitride membrane. Arbitrary nanoscale patterns ar ...

Cubic and oriented Ag nano-particles by high vacuum evaporation

Libero Zuppiroli, Detlef Berner

Ag cubes of uniform size (70nm) and self-assembled into two dimensional arrays are formed by physical vapor deposition. The formation of the Ag cubes depends critically on the substrate composition. While heat dissipation can control the crystallization of ...

Passive Guidance Forces of Polarized Linear Motors Combined with Levitation Actuators Working in Partial Vacuum – Application to Swissmetro

Marcel Jufer, Christophe Espanet

Maglev (>400 km/h) refer to Maglev such as the Japanese JR-Maglev MLX, the German Transrapid and the USA Inductrack. The Swissmetro Project, presenting a unique aspect of Maglev, is designed to work under partial vacuum (

Atmospheric and sub-atmospheric dielectric barrier discharges in helium and nitrogen

Christoph Hollenstein, Alban Sublet

Dielectric barrier discharges (DBDs) are investigated in helium and nitrogen as a function of pressure from 5 to 1000 mbar. Different regimes are observed: glow, Townsend, multi-peak and filamentary, depending on pressure, power and electrode gap. In heliu ...

SWISSMETRO - Polarized Linear Motor Combined With Levitation Actuators

Marcel Jufer, Patric Hagmann, Christophe Espanet

SWISSMETRO is a MAGLEV Project, designed for a speed up to 500 km/h in two tunnels under partial vacuum. The authors investigate new possibilities to combine the propulsion and levitation. Polarized inductors for the levitation are studied, implying a pola ...

Optimization of the fabrication of sealed capacitive transducers using surface micromachining

Paul Muralt

Processing issues for the fabrication of capacitive micromachined ultrasonic transducer (cMUT) arrays have been studied using surface micromachining. This work focuses on the critical steps of process fabrication such as membrane formation, sacrificial lay ...

Deuterium to helium plasma-wall change-over experiments in the JET MkII-gas box divertor

Richard Pitts

The deuterium and helium dynamics in the plasma and subdivertor regions of JET are compared during a sequence of similar ohmic and ICRH pulses where 100% He gas is injected into the JET vacuum vessel, whose graphite walls were previously saturated with deu ...

Magnetic triggering of ELMs in TCV

Yves Martin, Laurent Villard, Jonathan Bryan Lister

Experiments on the TCV tokamak have shown that rapid vertical movement of diverted ELMy H-mode plasmas can affect the time sequence of edge localized modes. The effect is attributed to the induction of an edge current during the movement of the plasma colu ...

Study of probes and substrates for low temperature atomic force microscopy and biological applications

Giovanni Dietler, Aleksandra Radenovic

The atomic force microscopy in ultrahigh vacuum and at low temperature demonstrated its excellent capability to reach atomic resolution. Nevertheless in the case of biological samples high resolution has been achieved only in very few cases. We demonstrate ...
