Extension of the operating space of high-beta(N) fully non-inductive scenarios on TCV using neutral beam injection

Olivier Sauter, Timothy Goodman, Duccio Testa, Alexander Karpushov, Antoine Pierre Emmanuel Alexis Merle, Mengdi Kong, Javier García Hernández, Matteo Vallar, Leonardo Pigatto

The fully non-inductive sustainment of high normalized beta plasmas (beta(N)) is a crucial challenge for the steady-state operation of a tokamak reactor. In order to assess the difficulties facing such scenarios, steady-state regimes have been explored on ...

Information-Theoretic Caching: The Multi-User Case

Michael Christoph Gastpar, Sung Hoon Lim, Chien-Yi Wang

In this paper, we consider a cache aided network in which each user is assumed to have individual caches, while upon users’ requests, an update message is sent through a common link to all users. First, we formulate a general information theoretic setting ...
