A capillary-discharge plasma source has been developed to |
|
produce a sodium-bearing plasma for fast Z-pinch |
|
implosion experiments. Peak currents of 40 to 50 kA from |
|
a 0.5-kJ capacitor bank were driven through a 0.5-mm |
|
diameter, few-cm-long capillary drilled in packed sodium |
|
fluoride powder to form the source. A nozzle was used to |
|
collimate plasma ejected from one end of the capillary to |
|
produce a 1 to 2-cm diameter, several-cm-long cylindrical |
|
plasma. Ions with velocities of 2.2 to 3.4 |
|
cm/microseconds were measured with biased charge |
|
collectors located at least 5 cm from the nozzle. |
|
Measurements of visible light from neutrals near the |
|
nozzle exit gave velocities of 1.5 to 1.7 cm/ |
|
microseconds. Indications of axial and radial |
|
nonuniformities of the plasma were observed in framing |
|
photographs of visible-light emission and in spatially- |
|
resolved spectral measurements. Capillary discharge, Z- |
