Jean Favier LAPP OPERA meeting Hamburg 5/06/04 GenIma: program to simulate emulsions

Jean Favier LAPP OPERA meeting Hamburg 5/06/04 Reconstruction optimization and parameters understanding are difficult for emulsions: Lack of data for various conditions ( particle type, angles, energies, fog densities, ambiant radioactivity integration times, etc) and poor statistics. Large feed-back time between beam tests and scanning ECC efficiency evaluation will be needed

Jean Favier LAPP OPERA meeting Hamburg 5/06/04 GEN: Particles generation in GEANT 3.2 Anything you like as particles, energies, dE/dX, vertices, neutrinos events, etc Keep the coordinates of energy deposites in a volume =200  200  288  3 2  1  dead-zone Density of 30 grains/100   -rays generated Track density controlled ( ex: 10/field of view)

Jean Favier LAPP OPERA meeting Hamburg 5/06/04 Fog and background Fog is randomly generated as single grain with a density of 6 grains/ (10  ) 3 time consuming, but Albums of fogs can be generated only once, and pictures added to the tracks ones Album of real emulsions data can be used also (fog+radioactivity fossiles tracks after refreshing) An ultimate uniform grey layer is added at the end (light scattering, long distance shadows)

Jean Favier LAPP OPERA meeting Hamburg 5/06/04 An application:base track efficiency (extremely preliminary) Distorsion (0-40 mrad) Clustering: just threshold and saturation Start from top microtrack, open a 50 mrad cone Find n “clusters” in bottom road : n  6? Efficiency for base track association: 0.93 (0 mrad) Increase with angle 0.95 (300 mrad) Sysal filter or micro track finder responsible for this measured fact? Inject Genima pictures (or code ) in Sysal What is this dependency (if any) with the UTS,SUTS tools? :simulate pulse height

Jean Favier LAPP OPERA meeting Hamburg 5/06/04 Next steps… Release a Fortran version with documentation (Sysal) Pictures are in FEDRA (Dominique) “Albums” of various background Refreshing action parametrization Filtering in GenIma to reduce heavy pictures? and…neutrino events with several emulsions and lead ?
