Abstract

For TESLA it´s foreseen to measure the beam-profile with so called wire-scanners. A thin carbon fibre is moved through the beam and the number of scattered secondary particles is measured in correlation to the position. From that a beam-profile can be calculated as an average over many bunches of the beam. We successfully tested a diamond-detector in a heavy ion-beam with bunches of up to 3·10¹⁰O⁶⁺-ions and in a beam of 10¹⁰ electrons, as planned for TESLA. The dose of 10¹⁵e^-/cm² or more by one of the bunches foreseen for TESLA corresponds to the irradiation a vertex-detector receives during 10 years of LHC. With strip-detectors made from diamond the beam-profile can be measured online for single bunches, with more than one array of strips also for more than one direction. If fast electronics are used and bunches are not too short, even a longitudinal profile can be obtained. The results of our measurements will be presented and discussed afterwards.
