概要

• In the quartz capillary part (8mm Ф, 10cm in length) of this ion source with a coaxial magnetic field of about 800 gauss, an intense ionization is established by a collimated primary electron beam sent from one end of the capillary. No metal part being contained in the capillary, a high relative concentration of atomic. hydrogen is obtained, so that the proton percentage of the ion beam extracted from the other end of the capillary is very large (60〜70%) A proton output up to 1mA is obtained from a 1.3mm hole with a small consumption of power (<200 watts) and hydrogen gas (〜3cc per hour N.T.P.). The ratio of protons to consumed gas molecules is 10〜20%.
