Experimental Testing of the European TH1509U 170-GHz 1-MW CW Industrial Gyrotron-Long Pulse Operation

Jean-Philippe Hogge, Francisco Sanchez, Ioannis Pagonakis, Konstantinos Avramidis

The upgraded European 1-MW, 170-GHz continuous wave (CW) industrial prototype gyrotron (TH1509U) for electron cyclotron resonance heating and current drive in ITER was tested at the Karlsruhe Institute of Technology (KIT). In this work, we report on the ma ...

Side emissions during EC injection for PDI studies in FTU tokamak

Cristian Galperti, Gabriele Grosso

The evidence of Parametric Decay Instabilities (PDI) excited by the ECH power injected in O-Mode has been explored in FTU Tokamak, using the Collective Thomson Scattering (CTS) diagnostic. The experiments show evidences to support the hypothesis of low-thr ...

New particle formation in the southern Aegean Sea during the Etesians: Importance for CCN production and cloud droplet number

Athanasios Nenes

This study examines how new particle formation (NPF) in the eastern Mediterranean in summer affects CCN (cloud condensation nuclei) concentrations and cloud droplet formation. For this, the concentration and size distribution of submicron aerosol particles ...

Manufacturing and Tests of the European 1 MW, 170 GHz CW Gyrotron Prototype for ITER

Stefano Alberti, Jean-Philippe Hogge, Konstantinos Avramidis

An industrial 1 MW, 170 GHz continuous-wave (CW) gyrotron prototype has been manufactured in 2015 at Thales. The physical design is provided by the European GYrotron Consortium (EGYC) and is supported by the construction and the measurement of a modular sh ...

Field and frequency modulated sub-THz electron spin resonance spectrometer

Jean-Philippe Ansermet, Murari Soundararajan, Christian Caspers

260-GHz radiation is used for a quasi-optical electron spin resonance (ESR) spectrometer which features both field and frequency modulation. Free space propagation is used to implement Martin-Puplett interferometry with quasi-optical isolation, mirror beam ...

Improving T2 -weighted imaging at high field through the use of kT -points

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Kieran O'Brien, Florent Eggenschwiler

PURPOSE: At high magnetic field strengths (B0 >/= 3 T), the shorter radiofrequency wavelength produces an inhomogeneous distribution of the transmit magnetic field. This can lead to variable contrast across the brain which is particularly pronounced in T2 ...

Blob current structures in TORPEX plasmas: experimental measurements and numerical simulations

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Nicola Vianello, Davoud Iraji, Diane Virginie Marie Lançon

In the simple magnetized torus TORPEX, field-aligned blobs originate from ideal interchange waves and propagate radially outward due to del B and curvature induced drifts. Time-resolved two-dimensional measurements of the field-aligned current density J(pa ...

Nitrogen and carbon isotopic composition of the Sun inferred from a high-temperature solar nebular condensate

Anders Meibom, François Robert

We report high-precision measurements of nitrogen and carbon isotopic compositions of a carbon-bearing titanium-nitride (osbornite) in a calcium-aluminum-rich inclusion (CAI) from the CH/CB-like carbonaceous chondrite Isheyevo. The mineralogy and petrograp ...

Reduced complexity likelihood approximation for chaotic trajectory segments

Thomas Schimming

Recently, statistically optimal detection methods for communication schemes based on chaos have been developed. The decision criterion is based on the well-known maximum likelihood criterion. Unfortunately, the calculation of the likelihoods is of exponent ...
