| Outline of Final Research Achievements |
Active X-ray generator with pyroelectric crystal with increased X-ray intensity is designed and developed for future lunar and planetary landing mission, as the emission intensity from present pyroelectric X-ray generator (PXG) is not so strong for space mission.
The X-ray emission intensity depends heavily on several operation parameters as the size and species of pyroelectric crystal, the size and shape of metallic target film as electron collector, their geometry and condition of inner gas (kinds, pressure). Appropriate conditions to increase X-ray intensity have investigated by several experiments, and these parameters were decided on experimental results. X-ray intensity of our PXG is abount fifty times higher than that of commercial one (COOL-X by Amptek).
