Simulations for Nuclear Reactions
and Structure in Europe (SiNuRSE)

ML attended the annual meeting In January 2012

The work is well underway

Progress is going according to original schedule

Some Milestones already reached
Task 1: Development and benchmarking of physics based event generators



Subtask 1: Development of an event generator for light-ion induced
reactions (CEA, U-Liege)
√
Subtask 2: Development of an event generator for heavy-ion induced
reactions (GSI)
Subtask 3: Development of an event generator for elastic proton-nucleus
cross-sections and p-n reactions with focus on exotic nuclei (UCM).
Subtask 4: Development of an event generator for beta-decay including
delayed particle emission (n, p, alpha) (CSIC).
Subtask 5: Development of a gamma ray event generator for neutron
capture electromagnetic cascades (CIEMAT).
Subtask 6: Development of a software tool which allows the use in GEANT4
of cross sections from correct (neutron and ions) reaction data bases for
low-energy reactions. (CIEMAT).
Subtask 7: Development of an event generator for fusion-evaporation
reactions (IFJ)
Subtask 8: Improvement of Intra-Nuclear Cascade models for a better
prediction of one-nucleon-removal channel (CEA)
Task 2:
Deals with the development of virtual Monte-Carlo platform

Subtask 1: Basic framework structure, code management (USC);
→ FAIRroot

Subtask 2: Parameters database management (RUG);

Subtask 3: Detector integration, quality assessment (IFIN-HH, ISS).
√
Task 3: Involves a few well chosen test cases relevant for several
activities of the community

Subtask 1: The response of neutron detection systems (ATOMKI);

Subtask 2: The response of fast ejectile and heavy-ion detectors (RUG);

Subtask 3: The response of a calorimeter (USC).

FairRoot
Advantages in using the FairRoot Framework:
-Improve the efficiency of creating new experiment simulation software for new
detector projects.
-All of the tedious, low-level details of creating experiment software are already
addressed in a reusable package.
-Reuse code that has been pre-built and pre-tested.
- Increase the reliability of the new application and reduce the programming
and testing effort.
- Maintained at GSI (http://fairroot.gsi.de)
In short: Simple
Adaptive
Flexible

• Database Interface is in SVN
• Ongoing work:
• RuntimeDB connection and initialization scheme (GSI)
• Implementation of Generic Parameter Container (KVI)
• Preparation of realistic tests (Land02)
Postgresql
FairRoot new developments
Time Based Simulation for Event Merging
 simulate data stream as realistic as
possible
 Could be an alternative to the
merging of individual event
generators into a more complex
but more realistic one.
Thank you !
