A superposed epoch analysis of auroral evolution during substorm growth, onset and recovery: open magnetic flux control of substorm intensity [PDF]

Annales Geophysicae, 2009
We perform two superposed epoch analyses of the auroral evolution during substorms using the FUV instrument on the Imager for Magnetopause-to-Aurora Global Explorer (IMAGE) spacecraft. The larger of the two studies includes nearly 2000 substorms.

The COMIX polarimeter: a compact device for XUV polarization analysis

Journal of Synchrotron Radiation, 2022
We report on the characterization of a novel extreme-ultraviolet polarimeter based on conical mirrors to simultaneously detect all the components of the electric field vector for extreme-ultraviolet radiation in the 45–90 eV energy range.

Simulation and experimental investigation on the wavefront correction performance of a dual magnetic connection deformable mirror under high-power laser irradiation

Frontiers in Physics, 2023
Deformable mirrors (DMs) are widely used in high-power laser systems to improve the output beam quality. However, under high-power laser irradiation, the heat accumulates on the DM mirror surface and results in high-power laser induced distortions (LID),

More on Meta-Stable Brane Configuration [PDF]

, 2007
We describe the intersecting brane configuration of type IIA string theory corresponding to the meta-stable nonsupersymmetric vacua in four dimensional N=1 supersymmetric SU(N_c) gauge theory with an antisymmetric flavor, a conjugate symmetric flavor ...

Plasma cleaning of ITER first mirrors in magnetic field

, 2014
To avoid reflectivity losses in ITER optical diagnostic systems, plasma sputtering of metallic First Mirrors is foreseen in order to remove deposits coming from the main wall (mainly beryllium and tungsten). Therefore plasma cleaning has to work on large
