Radioisotope tracing of metallic deposits near a coaxial plasma gun exhaust
Brumwell, Robert K.
MetadataShow full item record
A coaxial plasma accelerator system was constructed by LT R. K. Brumwell, USN at the United States Naval Postgraduate School for the purpose of producing a high velocity plasma slug. Experiments were performed in an evacuated chamber. Operating procedures were established for the apparatus and calibration tests were performed which demonstrated reproducibility of accelerator discharges made under given conditions. Use of a radioisotope tracer technique to measure the deposition of a metallic plasma on a cold wall was thenHnvestigated, A series of tests was conducted which demonstrates the feasibility of this tracer method for determination of mass condensation on walls surrounding a high velocity plasma slug.
