This paper considers whether that particle beam can be generated with the required properties. Unavoidable beam divergence, caused by the neutralization process, acting on a charged particle beam, makes the beam spot size much larger than the sail diameter. Divergence cannot be efficiently reduced by laser cooling. Consequently the neutral beam driven method can&#8217;t succeed due to beam divergence. However, fast interplanetary missions are more credible, enabling fast travel of small payloads around the Solar System. We give examples of neutral particle beam-driven sail probes.<\/p>\n","protected":false},"featured_media":9880,"template":"","meta":{"_members_access_role":[],"_members_access_error":""},"pwb-brand":[],"product_brand":[],"product_cat":[56,59,167],"product_tag":[1204,546,488,2208,2935],"class_list":["post-9879","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2017papers","product_tag-beam-driven-sail","product_tag-directed-energy","product_tag-interstellar","product_tag-interstellar-precursor","product_tag-neutral-particle-beam","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\/9879","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\/9880"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=9879"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=9879"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=9879"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=9879"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=9879"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
