The key to high-precision polarization measurements by SCIP is a polarization modulation unit that rotates a waveplate continuously at a constant speed. The waveplate consists of two birefringent plates made of sapphire and quartz to achieve a constant retardation in a wide wavelength range. We have confirmed that the retardation is almost constant in the wavelength bands of SCIP and its variation is negligibly small under the operational temperature conditions (20 +/- 10 degree C). The rotating mechanism is a DC brushless motor originally developed for the high-precision polarimetric observations in a future space mission, and we developed the control logic optimized for the uniform rotation at 0.512 s/rotation. The fast polarization modulation is essential for investigating the magnetic fields of the dynamical chromospheric structures. We have verified that a rotation uniformity by the control logic can achieve the polarization precision of 0.03 % (1σ) required for SCIP, and also verified that such an excellent rotation performance is unchanged under thermal vacuum conditions simulating the flight environment of the SUNRISE-3 balloon.", "subitem_description_type": "Other"}]}, "item_3_description_18": {"attribute_name": "内容記述",

内容記述 | The Sunrise Chromospheric Infrared spectroPolarimeter (SCIP) for the SUNRISE-3 balloon experiment is a slit-scanning spectropolarimeter that simultaneously observes multiple lines in the 770 nm and the 850 nm bands with a polarimetric precision of 0.03 % (1σ). The key to high-precision polarization measurements by SCIP is a polarization modulation unit that rotates a waveplate continuously at a constant speed. The waveplate consists of two birefringent plates made of sapphire and quartz to achieve a constant retardation in a wide wavelength range. We have confirmed that the retardation is almost constant in the wavelength bands of SCIP and its variation is negligibly small under the operational temperature conditions (20 +/- 10 degree C). The rotating mechanism is a DC brushless motor originally developed for the high-precision polarimetric observations in a future space mission, and we developed the control logic optimized for the uniform rotation at 0.512 s/rotation. The fast polarization modulation is essential for investigating the magnetic fields of the dynamical chromospheric structures. We have verified that a rotation uniformity by the control logic can achieve the polarization precision of 0.03 % (1σ) required for SCIP, and also verified that such an excellent rotation performance is unchanged under thermal vacuum conditions simulating the flight environment of the SUNRISE-3 balloon. | |||||
