Characterization of Hydrogenated Amorphous Silicon Sensors on Polyimide Flexible Substrate

Sylvain Dunand, Nicolas Würsch, Jonathan Emanuel Thomet

Hydrogenated amorphous silicon (a-Si:H) is a material having an intrinsically high radiation hardness that can be deposited on flexible substrates such as polyimide (PI). For these properties, a-Si:H can be used for the production of flexible sensors. a-Si ...

Validation of 2D T e and n e measurements made with Helium imaging spectroscopy in the volume of the TCV divertor

Patrick Blanchard, Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Hugo De Oliveira, Cedric Kar-Wai Tsui, Nicola Offeddu, Filippo Bagnato, Lorenzo Martinelli, Sophie Danielle Angelica Gorno, Claudia Colandrea, Dmytry Mykytchuk, Artur Perek

Multi-spectral imaging of helium atomic emission (HeMSI) has been used to create 2D poloidal maps of T-e and ne in TCV's divertor. To achieve these measurements, TCV's MANTIS multispectral cameras (Perek et al 2019 Rev. Sci. Instrum. 90 123514) simultaneou ...

Fast ion generation with ICRF waves and beams in the Wendelstein 7-X stellarator

Mike Machielsen

The largest operating stellarator, Wendelstein 7-X, is of the quasi-isodynamic type. For this design to scale up to a fusion reactor, several criteria must be met, one of them being good fast ion confinement. The latter still has to be tested experimentall ...

Surface DBD degradation in humid air, and a hybrid surface-volume DBD for robust plasma operation at high humidity

Alan Howling, Ivo Furno, Fabio Avino, Lorenzo Ibba, Alexandra Waskow, Jia Han

Surface dielectric barrier discharge performance deteriorates in humid air, with permanent and/or reversible degradation of its components. Plasma operation in a humid environment is unavoidable when humid air or water-containing materials are treated. Exp ...

Terahertz surface modes and electron-phonon coupling on Bi2Se3(111)

Davide Campi

We present a combined experimental and theoretical study of the surface vibrational modes of the topological insulator Bi2Se3 with particular emphasis on the low-energy region below 10 meV that has been difficult to resolve experimentally. By applying inel ...

Two-dimensional Rashba metals: Unconventional low-temperature transport properties

Claudio Grimaldi

Rashba spin-orbit coupling emerges in materials lacking of structural inversion symmetry, such as heterostructures, quantum wells, surface alloys and polar materials, just to mention few examples. It yields a coupling between the spin and momentum of elect ...
