Title
Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP)
Abstract
The Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) is the international sounding-rocket experiment led by Japan and United States under the collaborations with France, Spain and Norway, for aiming the first measurement of the linear polarization in the hydrogen Lyman alpha line (121.567nm) with the high polarimetric sensitivity (0.1%), and inferring the magnetic field information in the chromosphere and transition region, where the gas-pressure-dominated photosphere changes to the magnetic-pressure-dominated corona.

The CLASP instrument, consisting of a Cassegrain telescope, a spectropolarimeter and a slit-jaw imaging system, was developed by Japan with the additional efforts of United States and France. It was launched at White Sands in United States on September 3, 2015, by using NASA’s sounding rocket, and successfully performed the polarization observation in Lyman-alpha. Coordinated observations with Hinode, IRIS and ground-based observatories (e.g. DST in Sac Peak) were also carried out.

The scientific data taken in this flight look so perfect that they must include many topics for the investigations. Their analyses is going on now. In this talk, I will show some current progresses.
