The ion-optical behaviour of acceleration tubes of different field structures has been studied by comparing the results of trajectory calculations with experimental data obtained in bremsstrahlung measurements. Intensities and end point energies of X-radiation were measured with a NaI(Tl) counter, while intensities and average energies were measured with thermoluminescent dosimeters (TLD). Dose rate distributions obtained with TLDs in the immediate vicinity of the tube were compared with those generated from data measured at the outer wall of the accelerator vessel. A similar procedure was followed in the case of homogeneous field tubes as well as for those of inclined fields with alternating or spiralling transversal components. The tubes were used for long operating times in a 5 MV Van de Graaff accelerator.
