Patent attributes
An apparatus for producing an atomic beam comprising an ionization chamber, an ion beam drawing device, a neutralization chamber and a voltage regulating device is provided. The ionization chamber generates an ion beam and the ion beam drawing device draws the ion beam out from the ionization chamber. The neutralization chamber and the voltage regulating device are disposed on the path of the ion beam. Moreover, the ion beam drawing device is disposed between the ionization chamber and the neutralization chamber and the voltage regulating device is disposed between the ion beam drawing device and the neutralization chamber. The energy of the ion beam can be reduced by the voltage regulating device. The ion beam is neutralized to a neutral atomic beam after passing through the neutralization chamber. Therefore, the apparatus for producing the atomic beam provided in this invention can effectively produce the neutral atomic beam.
