| Outline of Final Research Achievements |
Magnetic thrust chamber is one of the candidates of thrust system for laser fusion rocket. We performed experimental research (1) on visualization of magnetic field and (2) on the local plasma parameter measurement. First, we successfully developed ion backlight system with Xe ion source and applied it to a laser-produced plasma. In the experiment, however, the system did not work due to electromagnetic noise from large laser systems. In addition, we developed high-resolution spectrometer to measure the ion feature of Thomson scattering from a probe laser. We successfully measured local plasma parameters such as temperature, density, and drift velocity in relatively low density plasmas in a magnetic thrust chamber systems. The results suggested that the plasma was extracted from the magnetic nozzle, indicating the thrust system works as expected.
