  3. General • Most of the cleaning process with the 1020 are automatic. • The process is started by entering a cleaning time. • Once the process starts the specimen chamber will automatically pump and initiate plasma cleaning. The chamber will remain under vacuum until vented by the user. • VENTING TAKES 3 – 4 MINUTES. TURBO PUMP MUST SPIN DOWN.

  4. Gas Supply • Make sure the gas supply is on and there is gas. • Gas is an Argon – Oxygen mixture. • NOTE, just check the gauge. Do NOT adjust ANY valves.

  5. Check Control Panel • Normally the specimen holder will be under vacuum. • First check the control panel. • If the “HIGH VACUUM” light is illuminated, you must vent the specimen chamber.

  6. Venting the Specimen Chamber • Press VENT on the control panel. • The VENTING LED will illuminate. • It takes 3 – 4 minutes to vent the chamber.

  7. Chamber at Atmosphere • Wait until the ATMOSPHERE LED is illuminated before opening chamber.

  8. Remove the plug • After the chamber is vented, remove the plug from the TEM specimen port. • Place the plug in the plastic bag on top of the plasma cleaner. • The chamber is now ready for insertion of the TEM specimen holder.

  9. Insert TEM Specimen Holder • Insert the TEM specimen holder into the chamber. • The specimen holder may come to a stop but may not be fully inserted (see image). Do not push on the specimen holder at this time. WAIT.

  10. Set Cleaning Time • Using the number pad on the control panel input the cleaning time. Cleaning time for most TEM specimens is 30 sec to 5 minutes. • Press SET to start the pump down and cleaning cycle.
