Numerical and experimental investigations of a microwave interferometer for the negative ion source SPIDER

Ivo Furno, Rémy Jacquier, Riccardo Agnello

The electron density close to the extraction grids and the co-extracted electrons represent a crucial issue when operating negative ion sources for fusion reactors. An excessive electron density in the plasma expansion region can indeed inhibit the negativ ...

Slice-Less Optical Arbitrary Waveform Measurement (OAWM) in a Bandwidth of More Than 600 GHz

Tobias Kippenberg, Grigorii Likhachev

We demonstrate an optical arbitrary waveform measurement (OAWM) technique that exploits optical frequency combs as multi-wavelength local oscillators (LO) and that does not require any optical slicing filters. In a proof-of-concept experiment, we achieve r ...
