Descripción
A team consisting of Japan, USA, Spain, and Norway is developing a
high-throughput Chromospheric Lyman-Alpha SpectroPolarimeter (CLASP),
which is proposed to fly with a NASA sounding rocket in 2014. CLASP will
explore the magnetism of the upper solar chromosphere and transition
region via the Hanle effect of the Lyα line for the
first time. This experiment requires spectropolarimetric observations
with high polarimetric sensitivity (˜0.1%) and wavelength
resolution (0.1 Å). The final spatial resolution (slit width) is
being discussed taking into account the required high signal-to-noise
ratio. We have demonstrated the performance of the Lyα
polarimeter by extensively using the Ultraviolet Synchrotron ORbital
Radiation Facility (UVSOR) at the Institute for Molecular Sciences. In
this contribution, we report these measurements at UVSOR together with
the current status of the CLASP project.
