Description
The Kassiopeia particle tracking framework is an object-oriented
software package utilizing modern C++ techniques, written originally to
meet the needs of the Katrin collaboration. Kassiopeia's target physics
problem consists of simulating particle trajectories governed by
arbitrarily complex differential equations of motion, continuous physics
processes that may in part be modeled as terms perturbing that equation
of motion, stochastic processes that occur in flight such as bulk
scattering and decay, and potentially stochastic surface processes
occuring at interfaces, including transmission and reflection effects.
This entire set of computations takes place against the backdrop of a
fully-featured geometry package which serves a variety of roles,
including initialization of electromagnetic field simulations, gas flow
simulations, and the support of state-dependent algorithm-swapping and
behavioral changes.
In this tutorial a short introduction to the software is given and
afterwards the students can run the simulation by themselves and track
particles through the katrin mainspectrometer, investigating the
properties of the MAC-E-Filter technique.
Additionally a short overview of the visualization library VTK and the
tool paraview is given and how they can be used to create fancy 3d
pictures of the used geometry and the particle tracks just created
before.
