Garfield version 6.33 provides additional functionality for the simulation of avalanche processes. This version is able to compute the signals induced by a single track in several electrodes, such as a collection of strips in a CSC.
FORCES
command plots, on request, a diagram which
shows whether a wire is in stable or labile equilibrium.
The CHANGE-VOLTAGES
command now also works for
planes and for the tube.
PROJECTED-PATH
integration parameter,
which to a large extent eliminates the dependence of the avalanche
size on the Monte Carlo step size. On the other hand, a new
procedure RND_MULTIPLICATION
has been written which
simulates the avalanche fluctuation over a fixed path, taking
attachment and multiplication into account.
LAYOUT
graphics command.
RND_MULTIPLICATION
mentioned before, and
random number generators according to functions and histograms
(RND_FUNCTION
and RND_HISTOGRAM
). The
function random number generator is based on the
FUNLUX routine from the CERN program library.
Garbage collect for matrix assignments in loops has been improved.
