This tube has the cathode at
the small end, with a Maltese cross that can be set vertically or horizontally.
The aluminum cross will cast a shadow on the larger fluorescent end of
the tube. |
 |
The Crookes tube running off
a Ruhmkorff coil.
The gap at the top of the coil is
set to limit the voltage produced by the coil, thus limiting the energy
of the x-rays produced by the tube. Go here
for more pictures of the tube in operation. |
