D424800100013 The mass of the foils had been measured before and D424800100014 after the evaporation and from the difference - D424800100015 assuming that the evaporated layer is uniform - D424800100016 the number of target atoms were calculated. D424800100017 The absolute number of target atoms and the uniformity D424800100018 have also been determined by PIXE method. D424800100019 The precision of the determination of the number of D424800100020 target atoms was better than 3% and the thickness was D424800100021 found to be uniform within 2%. D424800100022 The agreement between the results of the two methods D424800100023 used for thickness determination is within 4%.

D424800100031 After the beam-defining aperture, the chamber was D424800100032 insulated and a secondary electron suppression D424800100033 voltage of -300 V was applied at the entrance of D424800100034 the chamber. D424800100035 Each irradiation lasted between 8 and 24 hours. D424800100036 The current integrator counts were recorded in D424800100037 multichannel scaling mode, stepping the channel every D424800100038 10 min to take into account the possible changes in D424800100039 the beam current.
