number.of.field.components

Handling of mixed particle fields

A variable describing how many components
 are used for the field. This also dictates the array lengths of all following
 variables.

Particle energies (array of size
 <code>number.of.field.components</code>, see also <code><a rd-options="" href="/link/E.MeV.u?package=libamtrack&version=0.6.3" data-mini-rdoc="libamtrack::E.MeV.u">E.MeV.u</a></code>

E.MeV.u

Particle type indices (array of size
 <code>number.of.field.components</code>), see also <code><a rd-options="" href="/link/particle.no?package=libamtrack&version=0.6.3" data-mini-rdoc="libamtrack::particle.no">particle.no</a></code>

particle.no

Fluences (if positive), or doses (if negative,
 array of size <code>number.of.field.components</code>), see also
 <code><a rd-options="" href="/link/fluence.cm2.or.dose.Gy?package=libamtrack&version=0.6.3" data-mini-rdoc="libamtrack::fluence.cm2.or.dose.Gy">fluence.cm2.or.dose.Gy</a></code>

Many functions in libamtrack offer the possibility to consider
 mixed particle fields. These fields are composed from a finite number of
 specific nuclids defined by <code><a rd-options="" href="/link/particle.no?package=libamtrack&version=0.6.3" data-mini-rdoc="libamtrack::particle.no">particle.no</a></code>. All particles of an
 individual component are supposed to have exactly the same energy (given by
 <code><a rd-options="" href="/link/particle.no?package=libamtrack&version=0.6.3" data-mini-rdoc="libamtrack::particle.no">particle.no</a></code>), without spread. Thus an energy distribution has
 to be describe in discrete energy steps.
Below is a compilation of the arguments a mixed field is described by.
 Depending on the function all or a subset are necessary. If arrays of length
 > <code>number.of.field.components</code> are entered, the additional data will be
 ignored. If array hold too few data, the computation will not be executed.

R interface to the open-source, ANSI C library 'libamtrack' (http://libamtrack.dkfz.org). 'libamtrack' provides computational routines for the prediction of detector response and radiobiological efficiency in heavy charged particle beams. It is designed for research in proton and ion dosimetry and radiotherapy. 'libamtrack' also includes many auxiliary physics routines for proton and ion beams. Original package and C-to-R conversion routines developed by Felix A. Klein.
