抄録

An α-ray imaging chamber has been developed based on a gaseous micro-time-projection chamber with a low-α emission μ-PIC in a low radioactivity structure. The detector offers the advantage of position sensitivity, which allows to image the α-ray contamination for the sample. It measures the α-ray rate in the sample region and a background region at the same time, thus that the net α rate from the sample can be evaluated efficiently by subtracting these rates from each other. In this work, the measurement results for several samples using the detector is provided.
