Old/merge/miscellaneous

This page should probably be merged into Ion thruster. Is there any reason to keep it separate?

Yes, you would have to merge Hall_effect_thruster as well with Ion thruster. Both are ion thrusters and to have a article about one and not another, when both have equal levels of publsihed information about them would present a lopsided view of this feild of technology to the reader --BerserkerBen 22:18, 22 Mar 2005 (UTC)

I'm not entirely sure I agree, but I've rearranged ion thruster so that it presents the different possibilities. This page still direly needs attention. --Andrew 07:09, Mar 31, 2005 (UTC)

Grammar point: In the History section "These thruster" should probably be "These thrusters". --Mstangeland (talk) 02:21, 24 March 2011 (UTC)[reply]

The dead link at the bottom of the page has moved to here. Wasn't sure if I should edit the main article to change this, though. --Tiddlydum (talk) 15:18, 25 February 2012 (UTC)[reply]

Editing needed ? - ion optics, sentence structure

1. ion optics? Hello? Please don't use unexplained jargon. Optics is DEFINED to be about LIGHT, although a case could be reasonably made about EMR. Expecting the reader to merge ions with light is either naive or absurdly optimistic.

2. "Kaufman type engines require at least supplies to the cathode, anode and chamber, whereas the rf and microwave types require an additional rf generator, but no anode and cathode supplies." I would have to work very hard to construct a more opaque structure for this sentence. Use "at a minimum" and "while", not "whereas". (hey, you MIGHT even want to make a point here!) sigh.

About point 1, "ion optics" is quite a common term in the art for guiding or focusing ion beams, see e.g. this book.^[1] Ileresolu (talk) 13:56, 18 August 2016 (UTC)[reply]

Positive grid

The article needs also to explain how positive ions go through the positive grid without been pushed back by the positive grid before they approach it. Wikibilig (talk) 13:43, 23 January 2021 (UTC)[reply]

What is Kaufman type

How is this sub-type of gridded ion thruster defined ? Is it just about how the ions are produced (eg all or a sub type of electron bombardment ?) ? or how they are accelerated ? - Rod57 (talk) 12:44, 24 November 2021 (UTC)[reply]

Seems from [1] that Kaufman type means the gridded ion thrusters that use an electron bombardment ion source. - Rod57 (talk) 19:16, 29 November 2021 (UTC)[reply]
