The
CASINO acronym has been derived from the words "monte CArlo SImulation of
electroN trajectory in sOlids". This program is a Monte Carlo simulation
of electron trajectory in solid specially designed for low beam interaction
in a bulk and thin foil. This complex single scattering Monte Carlo program
is specifically designed for low energy beam interaction and can be used
to generate many of the recorded signals (X-rays and backscattered electrons)
in a scanning electron microscope. This program can also be efficiently
used for all of the accelerated voltage found on a field emission scanning
electron microscope(0.1 to 30 KeV).
What can CASINO do?
This program is designed to simulate a large amount of electron trajectories
in a solid of your choice. The main idea is to simulate enough electron
trajectories to represent the condition used to image structures in a
scanning electron microscope (SEM). Thus it is possible to predict
theoretically the signals observed in the SEM. This Monte Carlo program
use different models to simulate the interaction of electrons with a
solid. For now, the versions 2 of CASINO produce the following signals:
backscattered coefficient
and X-ray. It also handles those geometry : muti-layers samples and grain
boundary.
Why version 2?
Version 1 of CASINO was starting
to show some age with it's DOS based interface. A new Windows™ based interface
has made CASINO much easier to use.
Who wrote CASINO?
Version 1:
The Monte Carlo program CASINO has been programmed by the
research team of Raynald Gauvin (Ph.D., Full professor at Université de
Sherbrooke, Québec, Canada). The program has been initially programed by
Pierre Hovongton, Ph.D. and Dominique Drouin, Ph.D. in 1996 and it has been
updated by Paula Horny, M.Sc.A. student and by Hendrix Demers, undergraduate
student in 1999. All this work have been performed under the suppervision
of Professor Raynald Gauvin.
Version 2:
The new Windows™ based
interface and reprogramming of CASINO was programed by Alexandre Réal Couture,
undergraduate student, in 2000, under the suppervision of Professor Dominique
Drouin.
