Outline of Final Research Achievements |
We developed transition-edge-sensor (TES) microcalorimeters for gamma rays. The energy resolution of a single-pixel device with a 1 mm x 1 mm x 0.7 mm bismuth absorber was 0.88 keV for 1.17 MeV gamma rays. We fabricated position-sensitive TES devices with a 19 mm x 0.5 mm x 0.5 mm lead absorber and obtained 1 mm position resolution for 662 keV gamma rays. We also fabricated a position-sensitive TES device with a 20 mm x 1 mm x 1 mm bismuth absorber. We modeled the position-sensitive devices and the actual and simulated pulses were in good agreement.
