Abstract

Scintillating screens are widely used for transverse beam profile monitoring and pepper-pot emittance measurements at accelerator facilities. For high current beam operations at the GSI heavy ion UNILAC, several inorganic scintillators were investigated under different ion beam conditions. The imaging properties of various materials were studied with respect to light yield and imaged beam width. The measured properties show a strong dependence on the scintillating material and change significantly with screen temperature. The spectral response of the materials was mapped for different temperature levels, using a spectrometer in the visible and near UV range. The results clearly demonstrate that their temperature behaviour and scintillating properties are critical issues for high current operations and have to be taken into account for correct beam profile reading.
