Magnifier Videotape Available
All,
I've had some requests for single topic videos, and I finally combined
ongoing segments from 9 previous tapes to create this special 2 hr
magnifier research and experiment report tape. This new tape
includes the bulk of my magnifier work over the last 5 yrs, and
covers a variety of magnifier topics, and special techniques.
Index:
1. Characterization of extra coil wound with #20 magnet wire.
2. Driver pri and sec are described
3. View of completed magnifier setup
4. 5 to 12 amps gives 40" sparks shown
5. Larger toroid is installed
6. Sparks are measured using the arc-line meter method
7. Preliminary work on an air blast static gap assembly
8. Coupling is measured and increased
9. More turns are added to the secondary driver
10. Rotary gap problem is described
11. Arc-line meter gives erroneous results
12. Magnifier sparks reach 70", then 80" using pole pig
13. Main variac blows out
14. Efficiency studies at lower power are begun
15. Large toroid produces corona curtain
16. Vacuum plenum static gap unit is built and tested
17. Stacked magnifier with small extra coil is tested
18. An induction motor is modified for synchronous operation
19. The locked pattern of motor is verified under fluorescent lighting
20. The magnifier is powered by a series array of 4 MOT's and gives
62"+ flaming arc streamers at 3 to 6kW.
21. A unique 12 point, 120BPS, super series quenching sync rotary
gap is built and described.
22. A 14.4kV potential transformer is installed
23. Part of the extra coil is rewound to fix racing spark damage
24. Driver is improved to prevent corona and flashover problems
25. Static series gap assembly is improved to reduce racing sparks
due to overcoupling
26. Supplimental resistive ballast is added
27. Super series sync gap is installed, magnifier is run at 1100 watts
28. Overview of magnifier setup
29. Coupling is loosened to reduce racing sparks
30. 7 amps gives 53" sparks
31. The old "wheel gap" rotary is re-installed
32. 14.4kV potential xformer fails, a new one is installed
33. Sync gap is re-installed, then the non-sync gap, various tests
34. Large cap/low BPS vs. small cap/high BPS
35. Drawing of firing points along ac sine wave at 120 and 240BPS
36. Caps are discharged as safety precaution in Equidrive mode
37. The wheel gap is re-installed and run at 700BPS
38. A new extra coil is tested
39. A 12 point super series quenching non-sync rotary gap is
constructed, balancing techniques are demonstrated
40. New rotary gap is tested in the magnifier
41. Electrode spacing is changed on the wheel gap
42. 120, 240, 360, and 720 BPS sync gap tests using clustered
or bunched electrodes
43. Drawings showing bunched un-evenly spaced electrodes for
sync gap. The gap is modified and tested in this new mode
44. Sync rotary is modified to give 600 BPS, with bunched un-even
asymmetrically spaced electrodes for constant bang size
45. Magnifier is changed to a stacked magnifier design, next the
extra coil is lowered to cause magnetic coupling between the
secondary and extra coil
46. The magnifier is converted to a classic TC
47. A normal tube TC gives sparks more than 3.5 times the length
of the secondary coil
48. A tube magnifier is run in the staccato mode
49. Discussion of magnifier coupling and quenching, with and without
a secondary tuning capacitor
50. Still photo section shows some magnifier photos
