Vertical Beam Size Due to Orbit and Alignment Errors
- Stanford Univ., CA. Stanford Linear Accelerator Center
The value of luminosity, synchrotron light source brightness, quantum lifetime, etc., for an electron storage ring is directly dependent upon the natural beam size and shape in the transverse phase space. These transverse beam parameters can be determined from the stationary particle distribution, $$ψ$$, which depends upon (a) quantum excitations determined by the horizontal and vertical energy dispersion functions nx,y and n'x,y in the machine, (b) radiation damping provided by the RF acceleration, and (c) coupling between the transverse betatron motions caused by the skew quadrupole and solenoid magnetic fields. We note a straightforward method to find $$ψ$$ is by solving the Fokker-Planck equation which conveniently takes into account these factors.
