The PhotoIonBar is an electrostatic charge remover using photoioni-
zation that neutralizes static electricity by irradiating the charged ob-
ject with weak soft X-rays.To neutralize static charges, ordinary ioniz-
ers generate ions by corona discharge and send them toward the charg-
ed object by air flow. Unlike these old methods, the PhotoIonBar emits
weak soft X-rays that directly ionize the air around the charged object to
neutralize static charges. The PhotoIonBar needs "NO AIR FLOW" and
generates "NO DUST" and "NO ELECTROMAGNETIC NOISE".

"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.

CHARGE NEUTRALIZATION EFFECT
In photoionization, ions are generated over the entire area irradiated with soft X-rays. This improves the charge neutrali-
zation efficiency and also shortens the charge neutralization time.

SOFT X-RAY SHIELDING
SHIELDING EFFECT (%)
Using the PhotoIonBar requires "soft X-ray shielding"
during operation. However, the soft X-rays emitted from the
PhotoIonBar are only at a strength of about 3 to 4.9 keV
and so only need the following materials for 100 %
shielding.

THICKNESS (mm)
Note 1: Shielding effect is measured when distance between PhotoIonBar and
survey meter is 100 mm and shielding material is placed between them
(survey meter side).
Note 2: The surface of PVC (polyvinyl chloride) plates may blacken when directly
irradiated by soft X-rays from a very short distance (within 100 mm) for a
continuous period over several months, but this is not a problem. Such
type of changes will not occur in iron and aluminum material plates.
