Description

Context
Comparing the experimental to the simulated efficiencies, a large factor is observed.
The simulated efficiencies are around a factor two bigger than for the experiment.

By using the same g4miniball code as basis than Martin Venheart used, we obtain the same factor of over-estimation of the photopeak efficiencies than him. Only the g4miniball part was the same, the production of the photopeak efficiency curves were absolutly decorrelated.

By using the same g4miniball code as basis than Martin Venheart used, the MiniBall Coulex efficiencies for larger distance are more or less reproduced (the incertitude comes from the unknow exact distance etween the target and the front face of the MiniBall clusters).

Simultion of the photopeak efficiencies with another code containing the MB geometry
Nigel Warr wrote a simple code including the MB cluster geometry. We envisaged to use it to reproduce the ODS setup and extract photopeak efficiencies.
Afterward, comparison between both results would remove the sprouds on the validity or not of the "g4miniball" photopeak efficiencies.
