The characteristics of Ne-based gases for position sensing have been investigated in the self-quenching streamer (SQS) transition region, using a single wire proportional counter with cathode strips. As the quenching gas we used CH4 with some mixing proportions. Position sensing was performed by the charge division method with a ratio-to-digital converter (RDC). With CH4 of more than 30% in concentration, the SQS transition appears clearly and the addition of C2H5OH makes the operation quite stable. It is impossible to detect X-rays with freon additive gases, i.e., a Ne-based magic gas mixture, probably due to a too strong electron attachment in this mixture.
