Introduction

INCL4.6 Intra Nuclear Cascade (CEA – U. Liège)

Abla07 Deexcitation (GSI)

Work package 4 INCL4.6-Abla07 in MCNPX

(and other transport codes)

Spallation model

Main improvements:

INCL4.6 n, p, π, d, t, 3He, α and A ≤ 8

Abla07 n, p, d, t, 3He, α and IMF

Low energy projectiles (E < 100 MeV)

Previous versions – INCL4.2 and Abla - in MCNPX2.5 (2.6 and 2.7 official)

So, time to implement INCL4.6 and Abla07 in MCNPX2.7b (and latter in MCNP6…)

Details D. Mancusi




•  IAEA benchmark 2008-2010 INCL4.5-Abla07 one of the best models

•  Late 2009 collaboration with LANL to implement the new versions

•  2010-2011 first calculations (Megapie – Isolde (Astatine))

•  New improvements INCL4.6-Abla07

•  New implementation Ntuple (PAW) capabilities APRIL 2012!!!

History




So, What?

2 examples:

•  Astatine production on Pb-Bi (Isolde)

•  ESS target (very very preliminary calculations)




At production on Pb-Bi

Target   Liquid Lead-Bismuth Eutectic

(LBE) in Tantalum cylinder (L=20 cm, r=1 cm)

Projectile   Proton beam: 1.0 and 1.4 GeV   Mean current: 0.1-0.3 µA

Results:  γ Spectro on and off line   Elements: He, Ne, Ar, Br, Kr,

Cd, I, Xe, Hg, Po and At   Mass distributions

Photograph from Y. Tall thesis

•  At decays to Po (α emitter)

•  At more volatile than Po

At can become a safety issue

Conclusion

•  INCL4.6-Abla07 improved (D. Mancusi)

•  Both in MCNPX (beta version), next step MCNP6

•  ISOLDE data (At): (first) good result!

•  Running time: according geometry, INCL4.6-Abla07 competitive with any in MCNPX

•  Ntuple capability: useful tool to analyze

•  And INCL4.6 also in Phits, GEANT4, …
