として、前述の王者が混在した状態で供給されている。When atoms are obtained by heating a metal, the atoms dissociate into positively charged ions and negatively charged electrons due to gas ionization. Furthermore, these ions and electrons also become neutral atoms through collision. That is, metal vapor obtained by heating a metal consists of neutral atoms, positively charged ions, and negatively charged electrons. For this reason, in known examples, the above-mentioned champions are supplied as an atomic beam to the laser isotope separation unit in a mixed state.

Therefore, there is a problem in that the above-mentioned ions and electrons are supplied to the isotope separation section, resulting in a decrease in separation efficiency.

The positively charged metal ions and negatively charged electrons generated at this time are repelled by the positive and negative electrodes or are attracted to and adhere to the electrodes themselves. As a result, only neutral atoms from which positively charged ions and negatively charged electrons have been selectively removed are supplied as the atomic beam to the laser isotope separation section.

Only neutral atoms can be guided to the collimator 8.
