| 单词 | Cockcroft-Walton generator |
| 释义 | Cockcroft-Walton generator The first proton accelerator; a simple linear accelerator producing a potential difference of some 800 kV (d.c.) from a circuit of rectifiers and capacitors fed by a lower (a.c.) voltage. The experimenters, Sir John Cockcroft and E. T. S. Walton (1903–95), used this device in 1932 to achieve the first artificially induced nuclear reaction by bombarding lithium with protons to produce helium: 11H + 37Li = 24He + 24He |
