DIY Linac?
Hello everybody.
After acquiring various radioactive metals, I'm getting interested in everything nuclear related. I read a lot on internet about DIY cyclotrons and
the fact that tey're not too hard to build. But they have one big disadvantage: they can only accelerate particles that are charged, so no neutrons.
What about building your own Linac that is capable of accelerating neutrons? Is it possible, or total fixtion?
Anyone has a clue, experiences or an opinion about this subject?
Sorry for my English. Thanks

Neutrons cannot be accelerated in a LINAC either. Because they use electromagnetic fields to accelerate (charged) particles.
It is possible to make neutrons with a LINAC though (or accelerators of other design) by impacting the right particles on the right target, perhaps
that confused you.

Indeed, I was confused. Sorry about that.
But, the big question remains for now: is there a way to accelerate neutrons to collide with atoms at home?

So far as I know you cant accelerate neutrons at all, since they aren't affected by electric/magnetic fields. They get produced in nuclear reactions
at a certain speed, and they can't be accelerated beyond that speed short of dropping them down a gravity well.

You could build an inertial electrostatic confinement fusion reactor (just barely within the reach of amateurs).

Long have I wondered if this were 100 percent true, how do Neutrons manage to end up Spin polarized by use of magnetic fields.

The two google links will not post right, and link to PDF's too large to post. Copy/paste in a new window does get the files.

Interesting, I never gave that any thought, but I found the following site provides a couple of good descriptions of various methods to produce
polarised neutrons:

got a strong alpha source? got Beryllium? there you go ! neutrons!
or, are you trying to accelerate alpha particles made from helium atoms? now there is an in interesting chalenge for you!
how much are you willing to spend? fascinating subject nuclear physics but hum.... aint cheap!
