Passive electrostatic vacuum particle collector

Disclosed are passive electrostatic particle collectors (10 & 12) for use in vacuum chambers (24 & 32) especially for a particle beam machine system (30 & 36) to collect particulates, such as dust and debris, generated by moving parts (16) within such chambers (24 & 32). These electr...

Zusammenfassung:	Disclosed are passive electrostatic particle collectors (10 & 12) for use in vacuum chambers (24 & 32) especially for a particle beam machine system (30 & 36) to collect particulates, such as dust and debris, generated by moving parts (16) within such chambers (24 & 32). These electrostatic particle collectors (10 & 12) comprise Tourmaline crystals (12) mounted on a bracket plate (10) and strategically located where dust and debris are generated. Also disclosed is a method of removing particulate material in vacuum chambers generated by moving parts by passive electrostatic particle collectors.
