TAHOMAG - vector-magnetograph for INTERHELIOPROBE
Abstract
Presented is the design of TAHOMAG - a vector-magnetograph for the INTERHELIOPROBE space mission. Since the instrument is supposed to conduct measurements under the conditions of strongly changing spacecraft velocity with respect to the Sun, we have chosen the scheme of a magnetograph with a spectrograph. A part of the spectrum of length 6Å is fixed in the vicinity of the FeI 6302 Å line. The contours of the Stokes parameters are recorded with a high spectral resolution. The polarization analyzer does not have mobile parts. The spatial resolution in the vicinity of the perihelion (0.3 a.u.) is expected to be 50-75 km.
