Cosmic Ray Detector (CRD)
Cosmic Ray Detector (CRD):
Eric would like us to build his CRD and refers to the Branley Coherer and this gives an ideal display of what is required:
"Coherer" Detectors
Quote:
"What I would like to see is the Geiger Tube ring the bell, ding - ding ding --------.
It would make a great hobby kit and serve a useful purpose.
It could even make money."
This is basically all the other content of the Colorado Spring's Notes that only receives an occasional reference and the incident where Tesla was able to detect the thunderstorm some 500 miles from his Coherer unit.
I am working on my CRD as I get time as he mentions some mods and tests to determine correct operation and I am attempting to do those now amongst other projects.
You can find this information back on page 12, Post 348.
The idea is to have the bell ring to reset the 0A4G.
Thyratrons:
Somewhat disappointed here as out of my total collection there are only the GE GL529 (4C35) and the 5C22 that are suitable.
Found this to be of interest:
Fusor Construction & Operation - Re: Pulsed Fusor #7 More Thyratron Questions
The trinity of thyratrons (glass) are:
3C45 ~3kv 30A
4C35 ~8kv 50A
5C22 ~16kv 150A
Richard Hull is something of an expert in this particular area.
Antique Electronic Supply have 28 x 3C45 on hand at US$25.98 and would find that difficult to beat elsewhere and don't mind telling you of this source.
The same source has 4C35 @ $104.61 1 only and 5C22 @ $125.37 2 only.
I am indeed fortunate to have what I have and shouldn't be complaining but it did take 4 years to collect those two so supply is pretty dismal in Oz.
