Polaron Coating System

This Hummer 6.2 plasma coater uses the atoms from a low pressure argon gas plasma to bombard a metal target (typically gold or gold/palladium). The metal atoms liberated by this bombardment ‘snow’ down on the sample giving it a conductive coating. (High voltage 1000-2000 volts with milliamps of current.)
The coating produced by this coater is intended to reduce sample charging caused by electron bombardment.
