TitleCockcroft, Sir John Douglas: certificate of election to the Royal Society
DescriptionDate stamp on reverse
CitationDistinguished for his investigations on nuclear transformations and on electro-magnetic problems. In conjunction with E T S Walton, a high potential DC installation giving 800 000 volts was constructed in order to produce high speed ions for transformation purposes. These pioneering experiments showed that lithium and boron were transformed on a marked scale by proton bombardment with the emission of swift alpha-particles. The nature of transformations both with protons and diplons has been investigated, and observations made on the production of artificial radioactivity. Results published in 'Proceedings'. Has also made calculations on skin effect in rectangular conductors at high frequencies (Proc Roy Soc) and on design of coils for intense magnetic fields (Phil Trans).
