2018 | ANNUAL REPORT 89 We have completed the first round of irradiation on the printed sensors at NC State PULSTAR Reactor. Our future work will focus on post irra- diation examination on the sensors irradiated at NC State.We will further improve sensor high-temperature thermal stability in order to extend the thermal conductivity measure- ment to higher temperatures.We will prepare sensors for irradiation experiment at MIT Research Reactor with significantly increased neutron flux and dose.
