Recent Activities (1/2)
ICC Simulation workshop (Nov 2015):
Presentations and Tutorials on:
AGATA code (M. Labiche)
Including a demo with LYCCA and a demo on Simulated Time Stamped data
SToGs toolkit (O. Stezowsky, I. Companis)
Detectors available: PARIS, AGATA, EXOGAM, FATIMA, N-Wall, DIAMANT, …
All Geometry are defined in gdml format
Could become the new framework for AGATA in if more and more users start
using it and develop it. (Connectivity to GammaWare & Femul)
All slides are still available here:

Recent Activities (2/2)
New ICC Simulation workshop 29th Nov -1st Dec 2016
Presentations and Tutorials on NPTool framework
User friendly framework (GEANT4 + ROOT)
MUST2, GASPARD, MUGAST, TIARA, HELIOS, PARIS, FATIMA ….
Built-in event generators for the kinematics of direct reactions.
Also GDML compatible
AGATA geometry could easily be exported into NPTool
New GitHub repository for gdml files:

5. agata/branch/GANIL/trunk/macros/gps
Recent developments
GEANT4 General Particle Source
GPS allows the user to simulate realistic sources (ex: 60Co, 152Eu, …)
Now also available in the AGATA code: ./Agata –gps
Ex. Macros also available in the GANIL branch svn repostory:
agata/branch/GANIL/trunk/macros/gps
However:
Issues with
some intensities !
152Eu

6. Recent developments GEANT4 GDML capability added
Implement Mechanical structure
Easy to include as ancillary: ./Agata –a N id
HoneyComb is invoked as ancillary with id number: 26
Ganil vacuum chamber + target frame has the id number: 27
OUPS (unique id not yet attributed)
Import/export detector from/to other framework

7. Future developments Other ancillaries (?) NEDA DIAMANT (?)
Not yet part of the AGATA svn repository.
Based on AGATA Code, but not defined as ancillary yet !
DIAMANT (?)
No update received.
Existing geometry file in ASC to be updated ?
New chamber to be added
Diamant as currently defined in ASC

8. Simulated Efficiency & P/T curves
(after tracking with mgt)
Setup: - Nominal
- 10ATC+1ADC
at backward angles
Isotropic source (Mg=1)
+ Vacuum Chamber
+ Anisotropy (E2 )
+ Beta beam=10%

9. Simulated Efficiency curves (Nominal)
Isotropic source with and without Chamber

10. Simulated Efficiency curves (Nominal)

+ Anisotropy E2

11. Simulated Efficiency curves (Nominal)
Adding bbeam =10%
+ Anisotropy E2

12. Simulated Efficiency curves for the compact configuration
+ Anisotropy E2

13. Simulated P/T curves (Nominal)

14. Simulated P/T curves (Nominal)
Adding E2 anisotropy
+ Anisotropy E2

15. Simulated P/T curves (Nominal)
Adding bbeam =10%

16. Simulation validation
GSI source run with 21 crystals
N. Lalovic et al. NIM A 806 (2016)
Full energy peak efficiency
@ 1172 keV
eExp (%)
eSim (%)
Core Common
2.38(2)
2.84(9)
Calorimeter
3.30(2)
4.21(8)
So: ~20% discrepancy on the Core Common Efficiency
~33% discrepancy on the Calorimeter Efficiency

17. Simulation validation
GSI source run with 21 crystals
N. Lalovic et al. NIM A 806 (2016)
Full energy peak efficiency
@ 1172 keV
eExp (%)
eSim (%)
Core Common
2.38(2)
2.84(9)
Calorimeter
3.30(2)
4.21(8)
Actually, 23 crystals were
considered in the simulations
So: ~20% discrepancy on the Core Common Efficiency
~33% discrepancy on the Calorimeter Efficiency

18. Simulation validation
GSI source run with 21 crystals
N. Lalovic et al. NIM A 806 (2016)
Full energy peak efficiency
@ 1172 keV
eExp (%)
eSim (%)
Core Common
2.38(2)
2.55(14)
Calorimeter
3.30(2)
3.71(17)
Now for 21 crystals !
So: ~7% discrepancy on the Core Common Efficiency
~12% discrepancy on the Calorimeter Efficiency

19. Summary Implementation of GEANT4 GPS & GDML capability
New “Ancillaries” added to the ASC svn repository using GDML
But NEDA & DIAMANT new chamber still needs to be added
Vacuum Chamber has a significant attenuation impact on Efficiency & P/T ratio at low energy.
Any Ancillary detector inside the chamber would also have an impact
E2 Ang. Corr. and bbeam (10%) have also an effect on Efficiency but almost none on P/T, as it seems.
Simulation of the GSI source measurement have been corrected but still overestimate the experimental efficiency.
GANIL source measurement would also be interesting to compare with.
