Resumen
A water-cooled XY-type current monitor was designed and built in the Cyclotrons Laboratory
of the Nuclear and Energy Research Institute (IPEN). It is a very simple design and easily
adaptable to the cyclotron beam lines. Tests were done demonstrating to be an instrument of
great assistance in proton beam position along beam transport line and target port. Nowadays
the XY-type current monitor has been widely used in 18F-FDG routine productions,
employing irradiation system which were originally designed for productions on 18 MeV
cyclotron accelerator only, however, applying the XY-type current monitor the target port
may be exchanged between the 30 MeV and 18 MeV cyclotrons and the observed results are
in perfect agreement with expected.
