Please, correct text in three places (numbered as 1, 2 and 3 below). New text has more references, it is more precise and more neutral. Also, I removed information which cannot be confirmed directly by references.
1. Instead of the phrase:
- He also developed the theory of the stability of electron and ion rings,[1]Template:Better source needed which is used in current laboratory experiments on magnetic confinement fusion (for example at TAE Technologies in California).Template:Citation needed
Please, put the phrase below which is more precise:
2. Also, please substitute the old paragraph:
- Lovelace proposed a new method of measuring magnetic fields,[3]Template:Better source needed developed a pioneering theory of intense ion beams in pulsed diodes, which are currently used in laboratories,[4]Template:Better source needed and proposed the theory of magnetic insulation, which is used in laboratories including at Sandia National Laboratories.[5]Template:Better source needed
