Issues Need to purchase light-tight conduit for full tracker –No cost estimation now –Hope to be purchased by Osaka Univ. –Maybe delivered in 1 month 2 weeks for 5 bundles of waveguides (corresponding to 1 station), in worst case –Expect shorter with the experience of station5 –Cutting into canes in advance can shorten the schedule Must fix total length to cut into cane –430cm? Must fix internal/external length for connectorization
