| Abstract |
In The Budker Institute of Nuclear Physics the accelerator-based source of epithermal neutrons was invented and now operates to be used in the boron neutron capture therapy. For several reasons the real beam flow in the facility differs from the calculated one. To take into account this distinction it is necessary to provide continuous monitoring of the beam parameters. In order to optimize the facility operation the beam should be followed not only during the formation but also while an acceleration takes place and the proton beam is thrown on the lithium target as the proton current and energy influence on the neutron output. In this way it seems to be a significant issue to measure the current, profile and also the position of the ion beam in a low-energy part of the accelerator. This work represents the results of experiments with the D-Pace WS-30 Wire Scanner Probe, which was installed in the low-energy part of the accelerator. The experiments were carried out under various conditions to vary the position and focusing control via the system of magnetic correcting elements. To correctly interpret experimental data it was necessary to take into account physical phenomena which occur during an experiment. In this way the effects which take place when the probe interacts with the beam were thoroughly considered. The obtained results allowed to restore the ion beam profile, define its size and position.
