Definition of BEAM for mathematical formulation of ion-optics optics What is a beam, what shapes it, how do we know its properties ? • Beam parameters, the long list • Beam rays and distributions • Beam line elements, paraxial lin. approx. higher orders in spectrometers • System of diagnostic instruments Not to forget: Atomic charge Q Number of particles n
Code TRANSPORT: (x, Θ, y, Φ, 1, dp/p) (1, 2, 3, 4, 5, 6 ) Convenient “easy to use” program for beam lines with paraxial beams Not defined in the figure are: dp/p = rel. momentum l = beam pulse length Defining a RAY central ray Ion-optical element All parameters are relative to “central ray” Code: COSY Infinity: (x, a, y, b, l, δ K , δ m , δ z ) Needed for complex ion-optical systems including several charge states different masses velocities (e.g. Wien Filter) higher order corrections Not defined in the figure are: δ K = dK/K = rel. energy δ m = dm/m = rel. energy δ z = dq/q = rel. charge change a = p x /p 0 b = p y /p 0 All parameters are relative to “central ray” properties Note: Notations in the Literature is not consistent! Sorry, neither will I be.
