L12536_15 Datasheet, PDF (2/4 Pages) Hamamatsu Corporation – ELECTROSTATIC CHARGE REMOVER USING PHOTOIONIZATION

"PHOTOIONIZATION" MECHANISM
When X-rays hits a stable atom or molecule, an electron is ejected out of the atom or molecule leaving a positive ion
(atom or molecule of positive polarity). The ejected electron then combines with another stable atom or molecule to
form a negative ion (atom or molecule of negative polarity). As a result, the same amount of positive ions and negative
ions are generated.
These ions are also generated in the vicinity of a charged object, and they are attracted to the charged object to neu-
tralize the static charges.
