26 February

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:

Lovelace developed the theory of the stability of electron and ion rings,[1] which has been used in plasma fusion experiments at Cornell.[2]

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

with a new one:

Lovelace and collaborator (Prof. Sudan) developed a pioneering theory of intense ion beams in pulsed diodes,[4][2] and proposed the theory of magnetic insulation (in collaboration with E. Ott),[5] which are used in laboratories.[2][6]

3. Please, substitute the phrase:

He invented a trapping mechanism of spin-polarized neutral gas, which has been experimentally demonstrated.[7][8]Template:Better source needed

with a new one:

Lovelace and collaborators invented a trapping mechanism of spin-polarized neutral gas, which has been experimentally demonstrated.[7][9]
