Abstract

A cylindrical-type drift chamber consists of an appropriate array of the cylindrical single wire proportional counter and has a simple structure. It was shown that a quadratic function reproduced the space-time relationship in the cylindrical-type drift chamber filled with the PR gas. The difference in the drift times in pair-cells was simply converted into the incident position of charged particles perpendicular to the anode wire with using the quadratic function of the spacetime relationship. Furthermore, the quadratic function improved the position resolution. A backgammon pattern was employed for the cathode pad of the cylindrical drift chamber. The cylindrical drift cell with the backgammon shaped cathode pad gave the position resolution along the anode wire. The position resolution along the anode wire was obtained to be 1.7 mm in average. The cylindrical-type drift chamber with the backgammon shaped cathode pad may be applied to a two-dimensional position sensitive detector with a compact structure and a simple signal processing electronics.
