Benford et al. (2019),\u00a0<i>JBIS<\/i>,\u00a0<b>72<\/b>, pp.51-55<\/h3>\n<p><b>Refcode<\/b>: 2019.72.51<\/p>\n<p><b>Abstract:<\/b><br \/>\nThe Starshot technology development program will build a modular Beamer system that will incrementally achieve steadily higher launch speeds. We examine what an intermediate-level Starshot Beamer system would be like and the relative merits of Beamer technologies in nearer-term missions. We quantify one such intermediate destination for robotic probes, the Sun\u2019s Inner Gravity Focus. A constellation of such probes would each see a \u201cpixel\u201d of the image plane. We describe cost-minimized Beamers driving probes to ~100km\/sec using laser, millimetre-wave and microwave sources and antennas\/ optics. Such systems would cost of roughly $1 billion at present costs. Substantial progress on driving down laser and\/ or millimetre-wave costs is essential to near-term system cost reductions. Power density in the sail varies substantially among the Beamers, with lasers giving the lowest sail temperatures.<\/p>\n","protected":false},"featured_media":9907,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[56,59,169],"product_tag":[2959,488,2962,2961,2963,2964,2960],"class_list":["post-9906","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2019papers","product_tag-beam-driven-sails","product_tag-interstellar","product_tag-laser-beam","product_tag-microwave-beam","product_tag-millimeter-wave-beam","product_tag-solar-gravitational-focus","product_tag-starshot","first","instock","downloadable","virtual","purchasable","product-type-simple","czr-hentry"],"jetpack_sharing_enabled":true,"brands":[],"_links":{"self":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product\/9906","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media\/9907"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=9906"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=9906"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=9906"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=9906"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=9906"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
