| Outline of Final Research Achievements |
I have been developing a TES type X-ray microcalorimeter array with a large absorber for the exploration of hydrates and organics in astromaterials. In order to improve the effective area, I adopted a mushroom type absorber that can be cover on the dead space between TES and TES. For realize the mushroom absorber, I have built a gold electroplating environment. I optimized the electroplating condition for TES absorber and got the stable electroplating conditions. I confirmed that the surface of gold film is flat by SEM.
