This paper presents the design parameters and numerous design improvements of this thruster. Three different versions of the thruster, with the same discharge chamber inner diameter of 80 mm, have been built and tested. The latest version of this prototype thruster presents significant improvements of the DC electrical connections to the grids and RF electrical connections to the RF antenna. For the second version of the thruster, plume ion energy distribution measurements are conducted using an indigenously developed retarding potential analyzer, and some of the measurement results are presented.<\/p><\/blockquote>\n<p><!--more--><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium\" src=\"https:\/\/nazlituranwritings.files.wordpress.com\/2017\/07\/rf2.png?w=1462\" width=\"1001\" height=\"616\" \/><\/p>\n<p>You can reach this paper with the following link:<\/p>\n<p><a href=\"http:\/\/bustlab.boun.edu.tr\/assets\/B40%20-%20JPC2017_paper_RF_v09_m04.pdf\"><span style=\"text-decoration: underline\">53rd Joint Propulsion Conference, Atlanta, GA, July 2017, also AIAA-2017-4891.<\/span> <\/a><\/p>\n<p>Some figures from the paper:<\/p>\n<figure id=\"attachment_707\" aria-describedby=\"caption-attachment-707\" style=\"width: 1173px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-707\" src=\"https:\/\/nazlituranwritings.files.wordpress.com\/2017\/07\/rpa.png\" alt=\"rpa\" width=\"1173\" height=\"340\" \/><figcaption id=\"caption-attachment-707\" class=\"wp-caption-text\">Measured I-V curve (left) and corresponding ion energy distribution (right)<\/figcaption><\/figure>\n<figure id=\"attachment_710\" aria-describedby=\"caption-attachment-710\" style=\"width: 1047px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-710\" src=\"https:\/\/nazlituranwritings.files.wordpress.com\/2017\/07\/rf.png\" alt=\"rf\" width=\"1047\" height=\"567\" \/><figcaption id=\"caption-attachment-710\" class=\"wp-caption-text\">Exploded view of the new RF ion thruster design<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>BURFIT-80, a prototype radio-frequency ion thruster, is designed, built and tested at the Bogazici University Space Technologies Laboratory.
