Easiest way to get x-rays is to rectify the output of a coil and hook it up to the anode (suction cup wire) of an old picture tube (<20 millitorr vacuum, lowest my vacuum meter can measure) while the filament is running. Not as good a real x-ray tube (otherwise the screen would melt pretty quick and cause the tube to implode from thermal shock with 300ma+), but just takes longer to get the same rems (higher energy x-rays tho depending on the coil). Now if i can figure out how to focus the rays into a narrow beam (aka laser) I'd have something cooler to play with.

These issues have been brought up in the past
more than once on this list. The ozone (O3) is
definitely an issue that must be addressed,
especially when operating indoors. O3 is toxic
in very minute concentrations and will cause
asthma-like wheezing, coughing and headaches
when one inhales it in concentrations that ex-
ceed the human toxic limit (Many of us know
this from first-hand experience). OTH, x-ray
production is usually not a big problem for
coilers as it takes HV excited electrons striking
a heavy metal target inside of a hard vacuum of
only a few torrs to produce significant le-
vels of hard, ionizing x-rays of energy levels
above a few 10s of kEVs. In other words, to
produce significant and dangerous levels of hard
x-rays requires more sophitication of equipment
than the average high voltage hobbiest has at
his disposal and they are certainly not going
to be produced "by accident".
