SVX-II beam test results

This paper presents the first results from the FNAL Meson test beam using SVX-II prototype detectors, taken at the MT-6 beam at FNAL. The signal size for double-sided double-metal detectors, as a function of radiation dose, is presented. The detectors were irradiated with 8 GeV/c proton beam at FNAL. The first results for detectors made from 6 in wafers is also given here. There is no decrease in signal size in the irradiated detectors with radiation doses up to 1.3 Mrad. The detectors made from 6 in wafers have comparable performance to detectors made from 4 in wafers.
