Solar spectropolarimetry with THEMIS
LESIA, Observatoire de Paris, 5 place Janssen 92195 Meudon, France
We report spectropolarimetric observations with THEMIS telescope multi-lines operating mode (MTR) during the last campaigns. We demonstrate the very favorable performances of THEMIS for investigations of the magnetic field and we report also observations devoted to the measurement of the scattering polarization. In that case, the signals are weak and are not "a priori" included in the THEMIS objectives but results show that THEMIS is a suitable instrument not only for strong field at high spatial resolution but also for weak signal at high polarimetric sensitivity. We describe briefly the multi-line spectropolarimetry mode (MTR) available at the franco-italian solar telescope THEMIS.
