Design of magnet and control of the beam emittance for Penning H－ ion source
H－ ion source Magnetron ion source Penning ion source magnetic field gradient index
2009/8/14
The design requirement and principle of the deflection magnet for Magnetron and Penning H－ ion source are discussed. It is proved that there exists a maximum emittance for the beam that may be transf...
Two-pion interferometry for a partially coherent evolution source
HBT correlation function partially coherent evolution source multiple scattering source collective expansion
2009/7/31
We give the formulas of two-pion Hanbury-Brown-Twiss (HBT) correlation function for a partially coherent evolution pion-emitting source, using quantum probability amplitudes in a path-integral formali...
