Sumario:A wire scanner is a device which moves a thin carbon target fast through a particle beam with a constant velocity [1]. They are widely used in accelerators to measure the beam profile, because they provide accurate measurements with a resolution down to 1 micrometer. In a high intensity beam the target suffers from strong heating, from the the electromagnetic coupling to the beam current [2]. After the fast initial heating, the wire is cooled down by various processes – heat transport along the wire, thermal radiation and thermionic emission. It might even sublimate or melt. The particles produced during the proton passage through the wire are measured in the detectors outside the vacuum pipe and based on their intensity the beam profile is reconstructed.
