Analysis of filtered silicon diode data from the MAGO II and MAGO III experiments

PDF Version Also Available for Download.

Description

The magnetic compression (MAGO) experiments were conceived by the All-Russia Scientific Institute for Experimental Physics (VNIIEF) several years ago, and only recently has Los Alamos National Laboratory (LANL) participated in joint US/Russian experiments intended to combine the advanced US diagnostic technology with the unsurpassed explosive pulsed power technology fielded by VNIIEF. On two of the four joint LANL/VNIIEF magnetized plasma generation (MAGO) experiments fielded thus far, filtered silicon diode measurements of the plasma emission were made. Both VNIIEF and Los Alamos have analyzed the data from those two sets of measurements. Here the results of the Los Alamos analysis are ... continued below

Description

The magnetic compression (MAGO) experiments were conceived by the All-Russia Scientific Institute for Experimental Physics (VNIIEF) several years ago, and only recently has Los Alamos National Laboratory (LANL) participated in joint US/Russian experiments intended to combine the advanced US diagnostic technology with the unsurpassed explosive pulsed power technology fielded by VNIIEF. On two of the four joint LANL/VNIIEF magnetized plasma generation (MAGO) experiments fielded thus far, filtered silicon diode measurements of the plasma emission were made. Both VNIIEF and Los Alamos have analyzed the data from those two sets of measurements. Here the results of the Los Alamos analysis are given. In these experiments sets of filtered silicon diodes were used to measure the plasma soft X-ray emission integrated by the different band passes of the thin metal and plastic filters. The filtered silicon diode diagnostic on MAGO III represented a considerable advance over the same diagnostic fielded on MAGO II, but experimental details resulted in data that is very difficult to interpret in a quantitative way. An attempt to derive the spectral character from some of the MAGO III data that might be salvageable does not seem worthwhile. The codes and procedures developed for MAGO III have been valuable for interpreting MAGO II data, and should also be valuable for interpreting future filtered silicon diode data. Because of the better understanding of the physics processes associated with this diagnostic, and the reasonable agreement with the VNIIEF analysis for MAGO II the authors have more confidence in their ability to interpret the filtered silicon diode data from future MAGO experiments. They believe that the filtered silicon diode data from MAGO II is consistent with emission from a long-lived hot magnetized plasma, and that the temperature and density deduced from the data are reasonably consistent with the temperature and density computed by the 2-D MHD code MHRDR.
