NANO5's R&D addresses fundamental issues in radiation transport simulation; it investigates conceptual and technological solutions to extend the current capabilities of the Geant4 toolkit to cope with a set of new experimental requirements.
The topics of research encompass:
They derive from concrete experimental requirements and are addressed through the collaborative effort of simulation experts and experimental groups.
Geant4 is nowadays a mature Monte Carlo system; it is widely used in a variety of experimental applications, as demonstrated by the fact that its reference article is the most cited publication in the Nuclear Science and Technology category of the Journal Citation Reports.
Geant4 is the
result of a R&D project,
RD44,
carried out between 1994 and 1998.
RD44
was launched at a time when the LEP experiments were running
GEANT 3 as a
well-established system refined throughout a decade of production service.
RD44
investigated the adoption of the object oriented technology and C++ for a
simulation system replacing
GEANT 3.21,
and developed the first functional version of the Geant4 toolkit released in
December 1998.
Since then, new functionality has been added to the
toolkit in the following releases; nevertheless, the architectural design and
fundamental concepts defining Geant4
application domain have remained substantially unchanged since their original
conception in the very early phase of
RD44.
The scientific context that has evolved since the
conclusion of Geant4
RD44
phase motivates new R&D on simulation methods. New experimental requirements have emerged in the
recent years, which challenge the conventional application domain of
The current activity is focused on the issue of simulation at different scale, requiring co-working condensed and discrete schemes. A set of propaedeutic investigations is taking place in the first stage to gain in-depth understanding of relevant physics problems and to evaluate candidate technologies in concrete prototype implementations.
