| Research Abstract |
We performed the development of a high-resolution spectrometer for observing Jupiter's infrared auroral intensity and it's Doppler shift in order to clarify the Jupiter's polar ionospheric dynamics. First we carried out detailed discussion on the characteristics of the scientific targets and accordingly, achieved the optical designing to measure Jupiter's aurora. We adopted an Echelle grating for this high-resolution spectrometer. Next we designed and fabricated some important elements of this instrument, such as the Echelle grating holder, the slit viewer and slit unit. However, on the third year in 2010 we discussed the budget allocation in detail, and found considerable shortage of the budget. Therefore, it is necessary to carry out the re-designing of optical system drastically to reduce the cost. Using the instrument with new optical design, we still achieve the scientific subjects of Jupiter's aurora. Mainly due to the re-designing review process, we could not complete the development of instrument during this research period. However, the development will be finised within two years.
