TRANSVERSE BEAM PROFILE MEASUREMENTS USING OPTICAL METHODS

Two different systems are currently under development at GSI’s heavy ion facility to measure transverse beam pro-files using optical emitters. At the GSI-LINAC for energies up to 15 MeV/u resid-ual gas fluorescence is investigated for pulsed high current beams. The fluorescence of N2 is monitored by an image intensified CCD camera. For all ion species with energies above 50 MeV/u slowly extracted from the synchrotron SIS a classical viewing screen system is used. Three different target materials have been investigated and their behavior concerning efficiency, saturation and timing performance is evaluated. Both systems (will) use CCD cameras with a digital read
