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 similar to 10(7) ions/s. The beam profile could be monitored on-line with 50 mum resolution. The detector performed satisfactory even after a dose of 90 +/- 40 Grad.

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 similar to 10(7) ions/s. The beam profile could be monitored on-line with 50 mum resolution. The detector performed satisfactory even after a dose of 90 +/- 40 Grad.
