| Abstract: |
A sounding-rocket experiment called the Chromospheric Lyman-Alpha
Spectro-Polarimeter (CLASP) is presently under development to
measure the linear polarization profiles in the hydrogen Lyman-alpha
(Lyα) line at 121.567 nm.
CLASP is a vacuum-UV (VUV) spectropolarimeter to aim for
first detection of the linear polarizations caused by
scattering processes and the Hanle effect in the Lyα line with
high accuracy (0.1%). This is a fist step for exploration of magnetic
fields in the upper chromosphere and transition region of the Sun.
Accurate measurements of the linear polarization signals caused by
scattering processes and the Hanle effect in strong UV lines like
Lyα are essential to explore with future solar telescopes
the strength and structures of the magnetic field in the upper
chromosphere and transition region of the Sun.
The CLASP proposal has been accepted by NASA in 2012, and the flight
is planned in 2015. |
