first class prize of science & technology progress award of CAS in 1986，first class prize of national science & technology progress award in 1988
Solar Magnetic Field Telescope was proposed by AiGuoxiang who is a solar physical scientist，academician and director of National Astronomical Observatories，CAS。Nanjing Astronomical Instruments Factory (the former of NIAOT) was main undertaker of the project。Performance of the instrument located at Huailou Observatory Station of Beijing Astronomical Observatories can reach top-grade level of the world，which is first class level facility for solar observation in the world。This magnetograph consists of a 35-cm vacuum refractor, a 1/8? birefringent filter with 3 sets of KD*P crystal modulator, a CCD camera and an Imaging Technology 151 system controlled by computers. The photospheric vector magnetograms and Dopplergrams, chromospheric longitudinal magnetograms and Dopplergrams, corrsponding filtergrams can be obtained by this system.
