An improved X-ray polarimeter is briefly described and preliminary results of the measurements carried out on the satellite 'Intercosmos-7' are presented. One flare with considerable polarization (P~> 16%) was observed on 1972 August 4. Two other flares with rather low polarization (P ~ 4 %; P/> 2 %
Measurements of three X-ray flares in October/November 1970 abord the Intercosmos 4 satellite confirm the existence of polarization in the initial phase of the X-ray bursts. The polarization can be observed for a few up to ten minutes, and an increase in polarization is observed during secondary max
The polarization of hard solar X-radiation (> l0 keV) is calculated on the assumption that electrons get a non-isotropic velocity distribution in the initial phase of a flare. The bremsstrahlung generated by nonthermal electrons spiralling around magnetic field lines with discrete pitch angles is co
