Re: Tuning TCs
Hi gary,All,
Hmm a sort of tc scintillation? counter. Does anyone know what causes
the tube to glow. If it is just the rf field exciting the phospers in the
tube one could make a small neat meter out of some powder out of a tube.(yes
I know, don't breathe it in) sprinkled on to a plate covered with epoxy
stuck on the end of a small tube with a photocell at the other end. Dont
know how a photo cell would stand up to the field from a large coil though.
" 100 lumens at 10 ft " doesn't quite have the same ring about it as " 39"
sparks to a grounded rod" does though.
cheers
bob golding
