It has been shown that a commerciallyavailable scanner can be modified by the addition of an axial marker generator and water-cooled tubes in place of wires so that it can routinely scan high-current accelerator beams up to beam power densities of at least 35 kW/cm2. The versatility of the scanner has been demonstrated by its use with several different accelerators. In all cases, the installation of the scanner involved only simple adaptation to an existing beam pipe and the device was usually in place and functioning properly in less than an hour's time.
