THz-waves channeling in a monolithic saddle-coil for Dynamic Nuclear Polarization enhanced NMR

Stefano Alberti, Jean-Philippe Ansermet, Emile Jacques de Rijk, Alessandro Macor

A saddle coil manufactured by electric discharge machining (EDM) from a solid piece of copper has recently been realized at EPFL for Dynamic Nuclear Polarization enhanced Nuclear Magnetic Resonance experiments (DNP-NMR) at 9.4 T. The corresponding electrom ...

High aspect ratio sub-micron trenches on silicon-on-insulator and bulk silicon

Mihai Adrian Ionescu, Cyrille Hibert, Daniel Grogg, Marion Hermersdorf

This paper reports on the fabrication of sub-micron trenches on silicon-on-insulator (SOI) required in many MEMS devices and on bulk silicon. Trenches in the range of 100-500 nm had been etched with the deep reactive ion etching (DRIE) by using the SHARP ( ...

First experimental results from the European Union 2 MW coaxial cavity ITER gyrotron prototype

Timothy Goodman, Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Laurie Porte, Damien Fasel, Pierre Lavanchy, Ugo Siravo, Emmanuel Droz, Philippe Marmillod, Albert Perez, Ioannis Pagonakis, Blaise Marlétaz

The European Union is working toward providing 2-MW, coaxial-cavity, continuous-wave (cw) 170-GHz gyrotrons for ITER. Their design is based on results,from an experimental preprototype tube having a pulse length of several milliseconds, in operation at For ...

Improved magnetization transfer in solid-state NMR with fast magic angle spinning

Geoffrey Bodenhausen

The efficiency of magnetization transfer between different spins S such as chemically inequivalent carbon-13 nuclei in solid samples that are spinning at high frequencies about the magic angle can be enhanced by a phase-alternated recoupling irradiation sc ...

Progress on the ITER upper launcher millimeter-wave design and testing

René Chavan, Federico Alberto Alfredo Felici, Frédéric Dolizy

The aim of the ITER electron cyclotron heating and current drive upper launcher (UL) is to control magnetohydrodynamic activity in the plasma, in particular neoclassical tearing modes, requiring a narrow and peaked deposition of the radio-frequency (rf) po ...

Analysis and optimization of passive UHF RFID systems

Jari-Pascal Curty

Radio Frequency IDentification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is a small object that can be attached to or incorporated into a produc ...

Towards an optimal antenna for helicon waves excitation

Christoph Hollenstein

Helicon sources are known to produce high-density plasmas and have found many applications. Different types of antenna have been used for helicon excitation but none of them generate a radio-frequency (rf) field that matches the helicon wave field determin ...
