In terms of setups used in the weekend tests:
* Diathermy machine. Roughly equivalent to Adrian Marsh's except without the 'floating ground capacitor':
https://www.am-innovations.com/category/generators/generators-fischer-diathermy/ This diathermy machine operates at approx 3000kc.
* Disruptive Discharge Tesla Coil worked well at reproducing effects, almost equivalent to the diathermy machine setup. This makes sense as the core schematics are nearly equivalent.
* VTTC (vacuum tube Tesla Coil) setup also reproduced the effect but with diminished intensity. This also corresponded to threshold voltage+current. Basic Armstrong oscillator setup, with lots of current provided via microwave transformer. Also working at approx 350kc.
* HF radio equipment has NOT produced effects, most likely due to the low (<15kv) standing potentials achieved with it). Tested around 2000kc at up to 400w.
Some scattered notes regarding experiments and results
* Replica bulbs are atmospheric (no special fill gasses) that operate around 0.0001 Torr (upper limit of 2-stage rotary vane pumps)
- Effect disappears with diminished vacuum (a purple nitrogen glow means no rays will be emitted)
- Effect also disappears under high-grade vacuum (turbo-molecular pump).
- Narrow (~1in) bulbs have the correct glow but do not emit any rays (being 'dragged' down by the glass?)
* Tubes are all single-wire. No anode is present in any of these tests.
(no roentgen tubes can be found online or in literature that posses this characteristic)
* The emissions are cold-cathode; performance appears relatively constant whether the cathode is hot or cold.
* The phosphor screens are more weakly intensely illuminated than I expected. Requires a very dark room to perceive any effects. This is likely what was throwing me off in my initial tests the last two weeks.
* Rays could not be produced using HVDC alone, using a setup rated to >100kv. This also rules out 'conventional' X-ray actions.
* Voltage appears to be a critical factor, critical current remains TBD. Nothing occurs below 16kv P/P
* No rays produced at 16kv P/P @ 120cps AC (directly powered from NST)
* VTTC emissions confirmed that the bulb emits with HV RF, disruptive discharge not explicitly required.
* The cloud chamber did not produce any visible traces, only a 'cloud' of condensation.
https://www.bitchute.com/video/agx20KoUuhiT/ - Future attempts may produce more quantifiable results by using impulses so that smaller particle quantities can be observed
* The bulbs still produce the rays with a needle-point cathode rather than an electrode.
- IMO this effectively rules out collision/scattered Roentgen rays as any cathode reflections would have been tangential. The only viable Roentgen source in this case would be Bremsstrahlung (braking radiation) originating at the front face of the bulb.
- Heat can be felt from the front of the glass as well as close to the cathode, also supporting this possibility.
* Very crude HVL calculation suggests the rays produced are soft, perhaps 15-35kVp. Measurement was made by increasing layers of foil and comparing pixel brightness of phosphors on a resulting shadowgraph.
Going forward, my near-term focus is to improve detection and characterization (ie: perform high-quality HVL experiment to confirm and quantify ray penetration rates vs applied voltage/power). I also want to see what types of solid-state electronics can be used to detect (CDS cell, amorphous or polycrystaline solar cell, photodiode, phototransistors, etc.
The rays may also have electrostatic effect in open-air that we wish to falsify as well.
And finally, I'd like to reproduce and quantify the capacitor charging effect as it relates to both Tesla's Radiant Energy patents and to Dollard's 1980's Borderland experiments.
As always, everyone feel free to AMA and suggest any experiments you think might be worthwhile
