  1. quick check of fields in a test structure – design will be improved water jetted plate A Ross Engineering Toroid 20 kV bias 15.75 in ~5.6 cm ground plane shaped button cable connection electrode

  2. read C/cm as kV/cm

  3. Tipped toroid connection top of 3/8 in plate ¾ in below toroid center plate to floor 5.3 cm

  4. tipped toroid connection

  5. can raise toroid to equalize field on disk with plate corner

  6. 6 in radius sphere section 3/8 inch high fillet radius .02 inch 1/8 inch hole

  7. Hot spot is on disk edge for this case with top 7/8 inch below toroid center

  8. Ross Engineering T201 toroid 21 inch outside diameter 3 inch diameter ring

  9. The T201 is rated for 200 kV This is a check of this design to see what field they are running with a 200 kV rating. Calculate the field with toroid far from ground boundaries with a 200 kV bias The potential is shown here.

  10. Ross Engineering T201 toroid biased to 200 kV The field strength is shown here. The maximum field on the surface of the toroid is 20 kV/cm with a 200 kV bias. This is 2/3 of the breakdown field in air.
