초록

본 연구에서는 TID 센서를 모든 전자부품 내에 내장시켜, 유지보수를 위한 방사선 모니터링 기능은 물론, 이를 이용해서 회로를 보상하는 기능을 부가해서 전자부품의 수명을 연장시킨다. 또한 내방사선 효과가 높은 신물질을 이용한 신규소자를 개발하여 핵융합 용 소자의 응용가능성도 확인한다.

□ Purpose & Contents
Nowadays, Electronics components for nuclear fusion reactors use the conventional space application design principles. In this project, we invent very creative ideas for front-end readout integrated circuits at nuclear fusion reactor for extending the lifetime of the electronic components and facilitating the remote handling procedure at the fusion reactors.
For this research, we develop a TID sensor which is integrated inside all the electronic component, monitors radiation dose in real-time and compensates the effect of radiation for extending the lifetime of the circuit. Also, we develop a new circuit switching element by using new materials which characterize the radiation-hardness up to the order of 5.

□ Results
For this research purpose, we adapt both RHBD and RHBP for developing the MOSFET-based and new-material based electronic components. The research team consists of experts in the fields of rad-hard circuit designs, new switching elements, circuit modeling and nuclear fusion reactors.
1st sub-topic: rad-hard digital circuit, TID sensor and radiation test facilities.
2nd sub-topic: rad-hard front-end analog circuits and radiation compensation circuitries for extending the lifetime of the circuits.
3rd sub-topic: new switching component by using new material with very high radiation hardness.

4th sub-topic: compact models of radiation effects.
The expected research achievements are summarized as followings.
real-time monitoring technique of the radiation dose by integrating the TID sensor inside the electronic components.
techniques of extending the lifetime of electronic component for the fusion reactors by a compensation circuitry.
component design technique for increasing radiation hardness by applying new materials.
compact models for MOSFET and new switching elements. electric component test facilities of nuclear fusion reactors.

□ Expected Contribution
We expect that this research produces very promising results for the electronic components of the diagnostics at the fusion reactors. Therefore, we will try to establish good relationship with F4E so that we can be a procurement partner for fusion reactors.
The success of this study contributes to significantly improve the control precision of the nuclear fusion system. This research must be the corner-stone for the coming research. The meaning of radiation dose map inside of fusion experimental system is significant for radiation protection to personal hazard, design of diagnostic and control devices against radiation damage, and study for the radiation-hardened IC chip development. Also, this research can be easily applied to the space systems.
