# Magneto-Rayleigh-Taylor instability driven by a rotating magnetic field

## TL;DR

This paper provides theoretical analysis of the Magneto-Rayleigh-Taylor instability under rotating magnetic fields, showing that such fields can suppress instabilities in various configurations, with potential applications in fusion technology.

## Contribution

It offers new theoretical insights into how rotating magnetic fields influence the Magneto-Rayleigh-Taylor instability in different geometries, including potential fusion applications.

## Key findings

- Instabilities are alleviated for all modes with rotating magnetic fields.
- Both slab and liner configurations are analyzed using WKB and non-WKB approximations.
- Potential application to Theta-Z Liner Inertia Fusion is discussed.

## Abstract

We give theoretical analyses of the Magneto-Rayleigh-Taylor instability driven by a rotating magnetic field. Both slab and liner configurations with finite thicknesses are dealt with in the WKB and the non-WKB approximations. Results show that instabilities for all modes (combinations of wave vectors) are alleviated. We further discuss the potential application of the alternant/nested configurations of a theta and a Z pinch to the Theta-Z Liner Inertia Fusion (Theta-Z-LIF) concept.
