Results of launch experiments with solid armatures
conference paper
In this presentation, a summary is given of results of electromagnetic launch experiments recently performed at the TNO-PML Pulse Physics Laboratory in the framework of the investigation of fibre armatures for rail accelerator applications.
First part of the presentation concerns results obtained with respect to the long term goal of achieving arc-erosion free launch to hyper-velocities. To improve the experimental results obtained previously, a new launch package was designed which was assumed to strengthen the confinement of the fibre armature. In parallel, experiments were performed using hybrid armatures to obtain muzzle velocities well over 3 km/s and to study their behaviour when fully developed, stable plasma layers between a solid bulk and the rails are formed.
In the second pan, an experimental method is described to measure the bore growth during a launch experiment. The results show a characteristic interaction between the armature and the rail accelerator during launch.
