Advancing the Synthesis for Perdeuterated Small Organic Chemicals via Electrochemical CO2 Reduction

High deuteration yields are difficult to attain with conventional chemical synthesis methods. In this work, we demonstrate that deuterated chemicals can be produced using electrochemical CO2 reduction in the presence of D2O. The absence of H2O enables deut ...

Utilizing parametric instabilities to diagnose edge density fluctuations in TCV

Stefano Coda, Umesh Kumar

Two-plasmon decay instabilities (TPDIs) are a class of parametric instabilities where a gyrotron beam, polarized in X-mode, decays nonlinearly into two upper hybrid waves at approximately half frequency. Here, we present the design of a simple radiometer t ...

Experimental characterization of the TCV dual-frequency gyrotron and validation of numerical codes including the effect of After Cavity Interaction

Timothy Goodman, Stefano Alberti, Jean-Philippe Hogge, Damien Fasel, Jérémy Genoud, Ugo Siravo, Jérémie Dubray, Matthieu Toussaint, Falk Hans Braunmüller, François Jean Gaston Legrand

A dual-frequency gyrotron has been developed within the context of the recent Tokamak à Configuration Variable (TCV) upgrade. The gyrotron is designed to generate a 1 MW, 2 seconds RF wave at 84 or 126 GHz. Before integrating the gyrotrons in the TCV tokam ...

Representation learning algorithms for inferring machine independent latent features in pedestals in JET and AUG

Yoeri Renier Johannes Poels

Variational autoencoder (VAE)-based representation learning algorithms are explored for their capability to disentangle tokamak size dependence from other dependencies in a dataset of thousands of observed pedestal electron density and temperature profiles ...

An intense source of very cold neutrons using solid deuterium and nanodiamonds for the European Spallation Source

Mina Akhyani

The European Spallation Source (ESS), currently under construction, is based on a high -brightness, bispectral, low -dimensional moderator placed above a spallation target, intended to initially serve fifteen neutron scattering instruments. Within the upgr ...

Highlights of recent SPIDER results and improvements

Riccardo Agnello, Basile Marie Jacques Pouradier Duteil

Three years of experiments on SPIDER allowed characterization of the main features of the source plasma and of the negative ion beam, in the original design configuration. For the large dimensions of the source chamber, and of the extraction area, the inve ...

On the minimum transport required to passively suppress runaway electrons in SPARC disruptions

Carl Mathias Paul Hoppe

In Izzo et al (2022 Nucl. Fusion 62 096029), state-of-the-art modeling of thermal and current quench (CQ) magnetohydrodynamics (MHD) coupled with a self-consistent evolution of runaway electron (RE) generation and transport showed that a non-axisymmetric ( ...
