Publikováno v: Proceedings of International Conference on Particle Accelerators.

Radiation treatment of cancer dates back about 100 years. Today, mega-voltage electron accelerators are used routinely to irradiate many kinds of tumours. About two thirds of all cancer patients receive at least some radiation. More recently, other k

Ablation measurements using plasma disruption simulator

Autor: J.F. Crawford, J.M. Gahl

Publikováno v: [Proceedings] The 14th IEEE/NPSS Symposium Fusion Engineering.

A plasma disruption simulator (PLADIS) has been built and is operating at the University of New Mexico. PLADIS is a coaxial plasma gun system, operating in the deflagration mode. The system was designed to give a variable pulse length of 80-500 mu s
