Using APCS for Plasma Vertical Control at TCV

Basil Duval, Stefano Coda, Jean-Marc Moret, Federico Alberto Alfredo Felici, James Paley, Francesco Piras

Early tokamaks with circular cross-section plasmas were vertically stable in nature and no problems were reported on the control of the vertical position. However, the concept of vertically elongated plasma cross-section, with benefits to the energy confin ...

Modelling and design of a contactless energy transfer system for a notebook battery charger

Yves Perriard, Paolo Germano, Pascal Meyer

Some applications require an energy transfer without contacts and wires. The mutual inductive effects between two coils allow to transfer energy to an electronic consumer through an air gap. This paper presents an analytical model of a coreless transformer ...
