In order to search for neutrinoless double beta-decay, the DCBA (Drift Chamber Beta-ray Analyzer) experiment uses a momentum analyzer, which mainly consists of drift chamber and a uniform magnetic field. A beta ray from a source plate make helical trajectory in the drift chamber owing to the magnetic field. Momentum of each beta ray is obtained by three-dimensional track reconstruction. A test prototype called DCBA-T2 has been constructed and operated at KEK. Another prototype DCBA-T3 is also under construction to improve the energy resolution. The results of DCBA-T2 engineering run are described together with the status of DCBA-T3.

The DCBA (Drift Chamber Beta-ray Analyzer) experiment is being conducted at KEK for experimentally confirming the neutrinoless double beta decay (0vßß). We have focused our attention on the charged-particle tracks in DCBA experiment, and proposed to use the Hough transformation in sorting events for analyzing the tracks quickly and efficiently. The Hough transformation is one of the methods used in general for detecting circles and lines in pictures. In this article, we report the present status of the sorting event method using the Hough transformation.
