4.2 Cleaning the Emitters
Simco-Ion emitters have a serviceable life of three or more years in
a typical cleanroom environment when operated in conjunction with
a regular maintenance program. Evaluation of emitter condition
should be considered when cleaning the emitters. Worn emitter
replacement can be performed as part of a scheduled cleaning and
calibration.
1. Visually inspect each emitter electrode for signs of deposited
material. Typical deposits appear as a white coating on the
pointed tip region.
2. Simco-Ion recommends using the ITW-TEXWIPE model
TX726, CrushTube swab for cleaning the emitter electrodes. A
substitute method consists of a cleanroom swab saturated with
a solution of de-ionized water and isopropyl alcohol. These
items may be obtained from local cleanroom product suppliers.
3. The TX726 CrushTube swab is shipped with a protective sleeve
covering the white foam swab end. Remove the protective
sleeve to expose the swab end. Discard the protective sleeve.
The CrushTube swab has an inner glass vial of alcohol inside
of a plastic tube. Crush the inner glass vial by squeezing the
plastic tube, then tilt the foam swab end down to allow the
alcohol to wet the swab. Carefully insert the wetted swab onto
the emitter point, slowly rotate the tube, and withdraw. Repeat
until all deposited material has been removed. Each Crush-
Tube swab may be used to clean from 5 to 8 emitter tips,
depending on the amount of material on each tip. When the
Prior to any cleaning, power to the ionizer bar must be turned
off. This can be achieved using the MMI or by simply
disconnecting the bar.
Avant tout nettoyage, alimentation de la barre ionisante doit
être éteint. Ceci peut être réalisé en utilisant le MMI ou
simplement en débranchant le bar.
