Abstract: We have designed and built a new hodoscope for heavy ion beams consisting of two tracking stations equipped with silicon microstrip detectors operated at 130 K. Preliminary results from tests performed in the high intensity CERN-SPS Pb ion beam show that we were able to detect and identify each incoming ion up to a beam intensity of <f>∼107</f> ions/s. The beam profile could be monitored on-line with 50 <f>μ</f>m resolution. The detector performed satisfactory even after a dose of 90<f>±</f>40 Grad. [Copyright &y& Elsevier]
