beta-decay spectrum
The distribution in energy or momentum of the beta particles arising from a nuclear disintegration process.
beta-ray spectrometer, beta spectrometer
An instrument used to determine the energy distribution of beta particles and secondary electrons.
betatron; beta (ray) + (elec)tron
1. A doughnut-shaped electron accelerator in which the electrons travel in a circular path, being accelerated by a rapidly changing magnetic field.
2. An accelerator in which electrons are accelerated to high energies by an electric field produced by a changing magnetic field.
3. An electromagnetic apparatus for liberating electrons and accelerating them in a quarter-cycle alternating field to the required velocity for discharge against a chosen target.
