So some questions cornering your Cosmic Ray Detector:

Q1 - Why did you select or suggest the Phototube GL930 (or IP40) to detect the Cosmic Rays? The GL930/IP40 is an S1 spectral response and the graph shows a spike in sensitivity at around 3750 Angstroms and the graph does not show a plot below 3500, but if the line is projected down it looks as if it begins at around 3000 Angstroms. So this is the UV light spectrum. – Closest to Cosmic Ray wavelength? - The GL929 (or IP39), with a S4 spectral response may be an alternative. – The 929 is hard to find and very expensive if found. (Phototubes are somewhat of a mystery to most people including myself, so research was needed here).
Q2 - Should the Phototube itself be shielded with a shroud of some material to prevent false indications from ordinary UV light? So the only the Cosmic Rays pass through the shielding and trigger it, but any UV light does not pass through?
Q3 - It is speculated by some that as the Earth’s Magnetic Field weakens, (which it is doing so faster and faster apparently), the Cosmic Rays will spike in their intensity... Is this one factor in the importance of this detector? What are your deeper thoughts or purposes for this device, (because there’s always more than one reason or angle)!
Q4 - Is there a difference between ‘Tesla’s Cosmic Rays’ and what scientists of today call Cosmic Rays? - (Akin to Tesla’s Primary X-Rays and today’s X-rays)?
