Overview:<\/h3>\n

The condenser and objective steering voltages in the 20-622 electron gun control used on the PHI 660 scanning auger systems\u00a0 need to be adjusted periodically (check it as part of \u00a0 preventive maintenance service) for optimal image stability.<\/p>\n

If your image is stigmatic and moves a lot when you change your objective lens, you may want to check the condenser and objective steering voltages. A small amount of image movement is normal.<\/p>\n

Following this procedure will ensure that the steering voltages are operating properly and also that they are properly balanced.<\/p>\n

\u00a0\u00a0\u00a0 Procedure:<\/h3>\n
    \n
  1. Turn OFF the 20-610 30kV High Voltage Supply.<\/strong><\/li>\n
  2. Remove the 20-622 from the electronic console and extend the Lens control card (second board from the top). Support the board so that it is level with a non-conductive object. Remove all cables going to the 20-622 except for the power and the 40 pin ribbon cable between the PC147.<\/li>\n
  3. Connect a DVM between pins A and C on the J3 COND & OBJ Steering connector on the back of the 20-622.<\/li>\n
  4. Turn on the 20-622 and in AugerMap set the Beam voltage to 10kV<\/strong> and also set the COND X steering to 50% (mid-range).<\/li>\n
  5. Adjust R 27 on the lens control board for zero volts on the DVM.<\/li>\n
  6. Set the COND X steering to 100% and adjust R 25 for 205.0 volts DC.<\/li>\n
  7. Connect the DVM between pins B & D on J3.<\/li>\n
  8. Set the COND Y steering to 50% and adjust R 23 for zero volts.<\/li>\n
  9. Set the COND Y steering to 100% and adjust R 22 for 205.0 volts DC.<\/li>\n
  10. Connect the DVM between pins E & G on J3.<\/li>\n
  11. Set the OBJ X steering to 50% and adjust R 36 for zero volts.<\/li>\n
  12. Set the OBJ X steering to 100% and adjust R 35 for 205.0 volts DC.<\/li>\n
  13. Connect the DVM between pins F and H on J3.<\/li>\n
  14. Set the OBJ Y steering to 50% and adjust R 34 for zero volts.<\/li>\n
  15. Set the OBJ Y steering to 100% and adjust R33 for 205.0 volts DC.<\/li>\n
  16. Set the COND X, COND Y, OBJ X and OBJ Y steering to 50%.<\/li>\n
  17. Set the Beam Voltage to 3kV.<\/li>\n
  18. Check each pin again with respect to the chassis. They should all be zero volts with-in 50 mV DC and be stable. If they are not stable, the 7541 Dacs or 208H opamps on the error control board are usually the problem.<\/li>\n<\/ol>\n

    Calibration Complete.<\/p>\n
