does anybody have any thoughts on beta particle generators or have any links to research data. :shrug:
Beta particles are electrons formed by a weak mediated decay process in a neutron, \(n \to p + e^{-} + \nu_{e^{-}}\) or the antimatter partner, the positron, which is produced by a process roughly the reverse, \(p \to n + e^{+} + \nu_{e^{+}}\). Its simple to get a beam of electrons, old TVs and computer monitors used such a beam to make the image on the screen. The beam is formed by applying a magnetic field to a hot anode at the back of the box to 'pull' the electrons out. A beam of positrons is more difficult as you need to make them, they aren't contained naturally within any normal matter. Wiki will know.
beta particle right, but i was asking if anyone knew of any research into beta particle generator technology. maybe using carbon 14 or tritium or some other unstable beta particle.
Get one of those old pieces of Fiestaware or similar orange-glazed pottery or tile. They emit lots of betas from the Uranium radiodaughters. It's relatively low flux, however (a few kiloBq per pottery piece, or thereabouts).
Actually, the electrons are "boiled" out of the _cathode_ thermally, and accelerated and focused by _electric_ fields established by metal plates, grids, etc. maintained at various voltages. These components are collectively called the 'electron gun' and reside in the long, thin neck at the back of a crt. (cathode ray tube or picture tube as it is commonly called) Magnetic fields are used only to steer the beam, providing horizontal and vertical deflection.
beta particles i am building a beta particle generator and i was trying to get feed back and find out what people know of them.
