Technical Information


Complete ion gun system

Troubleshooting Hints

  • Locate the system manual
    • Manuals contain system-specific operating techniques and performance graphs taken during testing
  • Contact Kimball Physics
    • Experienced employees will answer any troubleshooting questions.
  • Note High Voltage dangers
    • Ask Kimball Physics for guidance in troubleshooting power supplies

Evaluations and rebuilds

Systems can be returned to Kimball Physics for evaluation and rebuild.
  • Ion gun rebuild: includes evaluation, cleaning, installation of a new ion source, and testing
  • Power supply repair: includes evaluation and testing
  • Call first for a return authorization number
  • Please return complete system: include the gun, power supply, and cables so all components can be tested together

Kimball Physics provides select reference material for ion gun technology available for download in PDF form.

Current technology ion gun systems have power supplies with FlexPanel controller.

For information pertaining to ion gun systems built before 2005, see Pre-2005 Technical Information.
