| Research Abstract |
We have developed, manufactured, tested and evaluated the ASIC that will be used for JEM-EUSO mission with collaboration between Japan and France. We confirmed that the power consumption, adjustment circuits and the photon counting abilities are almost satisfied as they are designed. We also examined the radiation tolerance of the ASIC by irradiating protons and heavy ions (Fe) at National Institute of Radiological Sciences (NIRS). We confirmed that there is no problem by the cosmic radiation to JEM-EUSO on the ISS for 5 years of operation. Moreover, we manufactured an integrated circuit system with this ASIC and FPGAs, verified the performance of the system and developed the software for the system operation. This integrated system was confirmed to have an expected performance. We also evaluated lens optics that were made in RIKEN and were confirmed that the optics has an expected performance. Finally, we set the TA-EUSO telescope into which these components were integrated at the Telescope Array site in Utah, USA and we measured background light. We confirmed that the integrated circuit module worked well as expected as a result.
