Neon and other Geissler Tubes Collection 

old Geissler tube

most likely my oldest Geissler tube

new type, with Argon

new type with Xenon

old X-Ray tube

Special Experimental tube, with valves in each end for easy vacum and gas connection

by changing the gax mixture and vacum levels we could change its color and brightness

here a lot more Neon to make its glow more orange

a special Neon sign F

it is the powder on the glass that increase efficiency a lot

a little test setup, vacum pump, neon gas, 10kV 100mA transformator, vario trafo for adjustable hi voltage, drop resistors for current limiting

another test setup including voltage doubler

a very special valved glass tube

length 510mm and diameter 30mm
