CPO calculates electrostatic/magnetic fields and the trajectories of charged particles through
those fields, a bit like SIMION. However, CPO differs fundamentally in its powerful
and highly accurate methods of calculation based on the
Boundary Element Method (BEM)
,
and it offers well tested space-charge, cathode emission, scattering and other advanced features.
Highlights
•
Extremely accurate BEM methods
proven with over 200 benchmark and
other examples
•
Comprehensive help system supported
with examples
•
Developed continuously since 1974 by
one of the leading research groups in
electrostatic systems (University of
Manchester, UK)
•
Vast range of capabilities and options
with advanced underlying algorithms,
all at a reasonable price
Capabilities
Particle trajectories are solved, accounting for space charge
and relativistic effects (Bulirsch-Stoer ODE solver).
Space charge is handled with iterative convergence tube and
mesh methods -- accuracy of 1% against theoretical results have
been obtained.
Cathode emissions limited by space charge are simulated,
including thermionic, field and extended Schottky emissions.
Supports Child’s Law, Langmuir, Fowler-Nordheim and Richardson-
Dushman relationships, plus user-defined cathode properties.
Electrostatic field solving is done to high accuracy using the
Boundary Element Method (BEM) rather than traditional FEM or
FDM methods. The BEM has unique advantages and is well suited
to space-charge, cathode problems and nano-structures in the pres-
ence of large electrodes. Adaptive surface meshes get smaller where
accuracy is critical.The BEM even easily simulates fine meshes and
non-enclosed systems. Dielectric version is also available.

Secondary emissions can be generated when a particle hits an
electrode. The current multiplication factor and energy and angular
distributions of the secondaries are chosen by the user.
Particle scattering and losses due to grid, background gas or
secondary emissions are given in examples included in the scattering
version of CPO Particle-particle scattering inside the beam is possi-
ble with the stochastic version. User-defined routines can be written
in C++.
Many examples of elecrostatic lens systems, including energy and
mass analyzers, are simulated. Electrode voltages may be oscillated at
low frequencies, as in the quadrupole.
Magnetic elements of various types such as solenoids, wire
loops and user-defined fields are available. Various contour and field
plots can be displayed.
Abberation coefficients and lens properties may be calculated
directly. An iterative automatic focusing option can be used to find the
optimum electrode voltages.
