Topic

To disengage the ion source, the large black handle has to be guided onto the right track of the stainless-steel barrel.

Environment

  • ISQ 7610
  • ISQ 7000 

Steps/Procedure

  1. Grasp the handle of the source exchange tool in one hand and use your other hand to pull the metal barrel out and away from the handle so that tool is fully extended.
  2. Twist off the round vacuum interlock knob located on the interior front panel and set it aside.
  3. Mount the source removal tool, twist, and push the barrel to the right until it clicks into place under the screw at the top of the slot.
  4. Loosen and twist the top part of the vacuum interlock handle to allow the entire handle to move up and down.
  5. Press the evacuate button.
  6. Once the “Ready to Open” light turns green, pull the handle up to open the interior ball valve.
  7. Slowly push the source exchange tool into the instrument.
  8. Because you are removing the ion source in this step, you will go down the right side of the metal track on the barrel.
  9. Twist the handle to the left to engage the ion source cartridge and pull the tool toward you and down the left side of the metal track on the barrel.
  10. Push the vacuum interlock handle down.
  11. Twist the source removal tool to the left to disengage.
  12. Set tool aside, close the chamber with the vacuum interlock knob.
  13. To expose the iron source, ensure that the alignment screw is placed in either of the steel barrel tracks.
  14. Pull down the stainless-steel barrel.
