The Auburn linear experiment for instability studies (ALEXIS) is a laboratory plasma physics experiment that is designed to investigate the role of spatially non-uniform E × B drifts using a magnetized cylindrical plasma column. This paper discusses the recent upgrades to the ALEXIS device, including improvements to the plasma source, gas management systems, and diagnostic suite.

    Laser–plasma instabilities that produce an unacceptably high level of hot electrons are potentially dangerous for both direct-drive and indirect-drive inertial confinement laser fusion. The hot electrons preheat the fuel and prevent compression of the capsule to the requisite conditions...
