Cosmic-Ray-Tolerant Electronics for Small-Spacecraft Deep-Space Explorations

Details of research theme

Deep-space explorations by small spacecrafts demand extremely low-power and long-lifetime electronics. There are many challenges. The number of errors in electronics usually soars because of interruptions by cosmic rays when the power is reduced. In addition, the cut of power in electronics relies on new materials and structures, which often make it difficult to secure their lifetime. This study aims to overcome such hurdles, using world-class high-sensitivity X-ray apparatus and Japan’s first laser apparatus in ISAS. Cosmic ray is a serious source that can degrade the reliability of electronics even on the ground. For example, some researchers indicate that cosmic-ray-induced errors are one of the hurdles that quantum computers must overcome. This study will help young researchers gain fundamental, professional expertise to tackle with such problems and secure our future information society.

Required abilities, qualities, and experience

PhD degree is required (including expected PhD by the date of adoption). Applicants must have experience with research
and development (R&D) on semiconductor devices or large-scale integrated circuits. R&D experience in the field of space may not necessarily.

Research environment after arriving at one’s post.

The department of spacecraft engineering in ISAS offers X-ray photoelectron spectroscopy (XPS) and femto-second two-photon absorption (TPA) laser systems. The XPS system has a world-class high-sensitivity, revealing various physical phenomena related to the lifetime of electronics in space environments. The TPA system is a Japan’s first, in-house system developed by students and faculty members of the department. It has been revealing various phenomena related to errors of electronics in space, successfully visualizing a new error mode in a low-power SRAMs, for example.
A full- and an associate-professors who have expertise in space electronics will support.
