Flashcards
High-energy Particles and Accelerators
Cards in this deck (6)
- 1Purpose of particle acceleratorsUsed to probe the nucleus more deeply, to produce and study new particles, and to provide information about the basic forces and constituents of nature
- 2Wavelength and resolution- Particles accelerated to higher energies/speeds can reveal more detail about the nucleons they strike
- The greater the momentum of the bombarding particle, the shorter its wavelength (λ = h/p)
- The shorter the wavelength, the finer the resolution that can be obtained - 3CyclotronUses a magnetic field to maintain charged ions, usually protons, in nearly circular paths
- 4Cyclotron period and frequency
- 5SynchrotronAccelerates relativistic particles, increasing the magnetic field with the energy of the particles to keep their orbital radius and frequency constant
- 6Linear accelerator (linac)- Electrons or ions are accelerated along a straight-line path passing through a series of tubular conductors
- Voltage applied to the tubes is alternating so that when electrons reach a gap, the tube in front of them is positive and the one they just left is negative
- Alternating polarity continuously accelerates the charged particle
- Drift tubes gradually increase in length as each charged particle moves further between successive polarity changes
