Magnetron Conference on 70 Years of Cavity Magnetron, held on 19 and 20 April 2010 at Bournemouth University UK


One of the first papers given was:


By Dr. Phil Judkins


A rather intriguing paper on hardly noticed aspects of attitudes between some British military establishments in respect to industry, as well as their stand (maybe aversion) against (some) developments originating from the United States.


Phil a I we both have decided not to agree to the conditions set by one of the CAVMAG2010 sponsors; my presentation was set at the closing end of this conference (maybe also due to its subject). This actually give us the freedom to publish our papers on the web, without squeezing restrictions. Hence, keeping it possible for everybody to download its content freely. However, in case of reproduction with an appropriate reference, of course.
