A study of ablation effects for an axisymmetric electromagnetic accelerator
- Nagoya Univ. (Japan). Inst. of Plasma Physics
In order to give the additional forward thrust to the projectile other than the electromagnetic force, the axial symmetric launcher called ablation mass driver (AMD) has been proposed using sequential z pinches in a cylindrical electrode array. The additional driving force originates from the reaction of ablating hot gas from the ablator on the rear of the projectile, since the Joule heating by the high electric current for electromagnetic acceleration is not negligiblly small. The ablated gas becomes plasma which propagates along the field-null line of z pinch, giving the forward thrust to the projectile. A proto type AMD has been built at Texas Tech University in order to see the capabilities of AMD as a launcher, although a study on the effect of ablation will remain as a future work. This paper describes a device of accelerating water blob for the study of ablation effect during acceleration together with the experimental results.
