We have carried out demonstrations of our mask design ideas for the pupil of SPICA and developed new free-standing masks (Mask-B and Mask-C) using thin sheets of nickel. Mask-B is intended to be used with a small inner working angle (IWA), and therefore, would be useful for direct observations of young Jovian planets very close to stars. With Mask-C a wide-field coronagraphic image is realized, so would be useful for efficient surveys of unknown exoplanets far from their stars and observations of diffuse targets such as circumstellar disks related to planetary formation. These mask have the general advantages of a binary pupil mask, i.e., (1) they are robust against pointing errors, and (2) they can, in principle, make observations over a wide range of wavelengths. Furthermore, the design of these masks gives them the following very important asset in that (3) they are applicable to the pupil of the SPICA telescope, which is partially obscured by a secondary mirror and support spiders. We obtained the first results of our laboratory experiments using Mask-B and Mask-C. The contrast of Mask-B close to the center was in the order of 10(exp -4) and that of Mask-C over an extended field of view (6-23 λ /D) was in the order of 10(exp -5)-10(exp -6).","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
