¢ Motivation: study energy resolution and fragmentation
¢ as function of Z:
¢ as function of bar thickness:
¢ as function of energy:
à To compare with measurements and to decide on optimal thickness
¢ Methods/materials:
¢ FOOT software
¢ FLUKA code
¢ Made automatized framework to simulate different Z, A, E, z, scintthickness, etc …
¢ Performed many simulations:
¢ 6 (thicknesses: 2,3,4,5,6, 7 mm)
¢ 8 energy values: 100, 120, 140,
160, 180, 200, 350, 500, 750 MeV
¢ 8 Z-values
à TOTAL: 6x8x8=384 simulations,
each only 1000 ev à 300 Gb
¢ ROOT for analysis

Method of cross section difference is crucial to obtain X section on pure elements: • Using C, C2H4 è cross sections on C and H • Using C, C2H4, PMMA è cross sections on C, O and H
These are specific measurements related with PT & RPS. But we are open to suggestions!!!
PMMA is a combination
of C,O,H.
