Project P12 

Optimization of Monte Carlo Tools and Comparison with Benchmark Data

Participants: CERN, LNF  ESR : 3 yrs, ER : 2 yrs (contact person : S. Miscetti, LNF)

Calorimeter simulation.

The detailed simulation of lead/scintillating fibre (Scifi) calorimeters of different structures using Monte Carlo tools (Fluka, Geant4) is relevant to evaluate their energy response and sensitivity to neutrons. Preliminary measurements of the response of neutrons between 10-180 MeV to a Scifi calorimeter show an efficiency enhancement by a factor larger than three with respect to expectations. Detailed comparisons will be undertaken with the best available physics models in Geant4 and Fluka. Optimization of the efficiency and response will be carried out utilising these applications.

The project comprises two main activities:

The comparison of detailed simulation with already existing and new test beam data, in order to understand the increased efficiency and to study the dependence of the efficiency on neutron energy and on calorimeter thickness.

The optimization of the efficiency with respect to calorimeter structure, lead/Scifi ratio, overall thickness, signal readout and type of fibre, using Monte Carlo techniques and the working-out a proposal for an optimized detector.
