Comparison between experimental measurements and calculated transport simulation for electron dose distributions inside homogeneous phantoms.

Comparison is made between dosimetric results measured on electron beams delivered by the three medical accelerators Sagittaire, Saturne and Neptune built by CGR MeV with the results simulated by a Monte Carlo method. In depth, the differences are small for moderate energies with scanned electron beams. In the penumbra region, the differences are small in all cases.
