| Outline of Final Research Achievements |
The purpose of this research is to develop a novel detector that combines a SOI pixel detector and superconducting detector to measure the ionization collection efficiency. Two technologies have to be developed: phonon detection with Al superconducting detector and a SOI pixel detector with super-low power consumption. We have developed a fabrication procedure using a lithography technique for the superconducting detector, and have achieved 90% production yields. We irradiated alpha particles from Am-241 to the silicon substrate and measured phonon pulse signals successfully. We have designed the SOI pixel detector using a circuit simulation, and have fabricated the SOI test chip. We have evaluate the performance of the chips.
