Abstract
TRANSPORT is a computer program used to design charged
particle beam transport systems. Beam line components which
can be represented are drifts, bending magnets, quadrupoles,
sextupoles, octupoles, solenoids, travelling wave accelerating
cavities, steering magnets, and plasma lenses. The effect
of the beam line on a charged particle trajectory is
represented by first-, second-, and third-order matrices.
Beam phase space dimensions and floor coordinates may also
be calculated. The beam phase space can be specified as
a matrix of variances and covariances or in accelerator
parameters. Its center can deviate from the reference
trajectory along which the magnetic components are placed.
TRANSPORT will do fitting, allowing the simultaneous
variation of up to 20 selected parameters to satisfy imposed
constraints. Misalignments and errors may be simulated and
their effect evaluated. In conjunction with a plotting
program such as TOPDRAWER, plots can be made of the beam
ellipse, any matrix element against accumulated length, and
the floor layout of the beam line, including three-dimensional
representations of the magnets.
Input can be in either the MAD compatable notation of
Christoph Iselin or in a strictly numerical format.
The parameters can be in any units desired. Physical
parameters and constrained quantities can be related by
algebraic expressions.
