In-Flight Measurement of Ten-Fold Compression of Magnetic Field*

In the last decade, simulation and theory have increased demand for the ability to magnetize experiments to the kiloTesla level. Physical limitations on energy storage mean that fields of this magnitude over a usable volume can only be achieved by compression. Field compression has been used to generate inferred kiloTesla fields, but such fields are usually inaccessible due to the high density, hot plasma surrounding them. In this talk we will present a field compression platform on the EP laser system at the Laboratory for Laser Energetics that could be used to apply a compressed magnetic field to a clear, usable experimental volume. An initial test of this platform was diagnosed with proton radiography and an in-flight field compression of roughly 10 times the initial field was measured. These experiments indicate that the platform can be expanded to both increase the field compression and usable volume for longer periods than the initial experiment.
