As far as I can determine in my searching, a "Farranti valve" is a vacuum tube or valve made by Farranti, except that a "Hopkinson–Farranti valve" is some kind of check valve used for boilers. I am unable to verify the claims of the article. Mangoe ( talk) 02:40, 21 July 2021 (UTC)
- The correct spelling is "Ferranti". Ferranti were a noted producer of electronic components. The component in question is a guard ring diode, primarily used in educational demonstrations as a way of demonstrating the magnetron approach to assessing the charge-to-mass ratio of the electron. The physics looks right to me, but I'm not a specialist. However, this link seems to support this. I don't think this particular valve merits an article in its own right - it seems reasonably clear that other equipment could be used in the educational environment, and there's no obvious reason to impute notability to a particular electronic component, even an interesting one like this - but it would be useful if the magnetron method for assessing the electron's charge-to-mass ratio were better covered in Mass-to-charge_ratio. Accordingly, I suggest we Delete, but request a suitable specialist to expand this section of the relevant article appropriately. RomanSpa ( talk) 07:40, 21 July 2021 (UTC)
