Abstract

We have been designing and developing DC- and AC-coupled double-sided and single-sided silicon strip detectors for tracking device in the international linear collider (ILC). We present the electrical characteristics of the fabricated sensors such as the leakage currents and the capacitances as a function of reverse bias voltage. We also discuss results of the radiation damage test with 45 MeV proton beam of a cyclotron in Korea Institute of Radiological and Medical Science (KIRAMS) in Seoul, Korea. The leakage currents and the full depletion voltage were measured to be less than 10 nA/strip and about 60 V, respectively. We conclude that developed sensors have an excellent safety margin of radiation hardness appropriate for the ILC. The results of the signal-to-noise ratio (SNR) of the fabricated silicon strip sensors with 90Sr radioactive source and the proton beam of the KIRAMS are also presented. The SNRs of the strip sensor are measured to be 25.0 and 6.7-16.4 for the source test and for the proton beam test, respectively.
