Some older monitors do warn of x-rays if you look at all the lables but I doubt there is any real danger. I have seen monitors that go into ion-death-beam mode if you take away the signal. All 3 electron guns fire straight forward and stay that way untill you give it a signal.

The thick lead-glass front screen of crt's protects us from the (soft) x-rays produced by typically 25-35 keV electrons hitting the shadow mask. Or at least that's what I've been lead (ha ha) to believe.

Considering topic title 'particle beam weapon' there's nothing with these cathode ray tubes other than being silly. (I guess that was also c. hooper's point)
Particle accelerators needed to get small amount of particles to relativistic speeds are building or district sized requiring insane amounts of power, and their best output can usually be stopped by meters of air.
(so I guess it's pointless to discuss those things as something amateur-practical).
While topic was opened with question about accelerating high-temperature plasma at much lower speeds I think Tesladownunder's plasma ring launcher is probably most sucessful and best things to follow.
Someone could try improving it, getting more speed, more plasma or hotter plasma, etc. but I doubt it could be something more than big (and dangerous) toy.

I think it´s no good idea to start experimenting with X-rays. They are really dangerous and hardly to control I think. The best way to produce X-rays is an old denist tube which can be sometimes found on ebay.
Hmm, its harder than i thought to built a particle gun. What about accelerating the plasma from an exploding or melting wire or maybe a metal liquid. I also thougt of a little ring accelerator to reach higher speeds.

What happened to the days when you just threw a brick at something when you wanted to do something to it? I'd maybe go for making a YAG laser rifle if I was going to try to make a practical ray of some sort. From what I've seen of the SSY-1, I would think the larger scale YAGs would be fairly powerful and could still be portable, even if you had to have a backpack or something.

I would stay away from using lasers (especially q-switched yag's) anywhere than a room with blacked out windows and a closed door... I couldn't imagine the lawsuit if someone claimed vision damage from a reflection

Lasers actually have a much bigger chance of being weaponised, adn they already have some of such uses, altough hand-carried weapons like such aren't really practical, since they have tendency to overheat the target instead of physical damage.
And they aren't really particle weapons so it's offtopic.

Yes there was research in this area. IIRC microwave based non-lethal crowd control is now available.
There have been other more exotic things developed over the years too. Bringing up questionable science usually causes some controversy and imminent thread locking,
