Status of the applied magnetic field capability on Z

Summary form only given. The capability to apply external magnetic fields is of interest to several areas of research on the Z pulsed power facility. The Inertial Confinement Fusion Program (ICF) will evaluate the modification of fusion plasma particle transport properties via flux compression of applied magnetic fields to >50 MGauss in the Magnetized Liner Inertial Fusion (MagLIF) concept.¹ The Dynamic Materials Properties (DMP) program will use applied magnetic fields for the Magnetically Applied Pressure Shear (MAPS) technique for measuring dynamic material strengths.² Other applications and research areas that may be interested in utilizing this applied magnetic field capability include magnetic flux compression experiments, magnetized gas puffs, magnetically stabilized wire-array Z-pinches, and magnetized astrophysical samples for fundamental sciences. The magnetic field generation requirements for the different research areas are similar and have overlapping requirements for field strength (1-10´s of T), pulse length (1-10 ms), magnet size (bore diameter and length ~ 1-10 cm), magnetic field energy (10-100´s of kJ) and split-magnet topologies for diagnostic and sample access. Because of the unique and energetic nature of experiments on Z, the integration and implementation of applied magnetic fields on Z presents some unique engineering challenges. Preliminary experiments utilizing the applied magnetic field are planned for early this year. The design, implementation, and experimental status of the applied magnetic field capability on Z are described.
