The Study Of Capability Of A New Kind Of Cathode Plane Drift Chamber

Drift chamber is the most representative gas detector, which has been used broadly in experiment physics, X-ray crystallology and biology. The most popular drift cells available are of the structure that locating one sense wire in the center and surrounding several field wires around, however, nowadays the structure are found to be less and less able to fulfill the requirement of high luminosity and good resolution of modern experiment physics, as a result, a new kind of drift chamber is proposed in this article using cathode plane instead of field wires to admit the demand. The feasibility is studied, the electric field, XT relationship and charge density of one single wire are simulated with Garfield; one prototype is produced, the spatial resolution, signal characteristic and gas gain are tested; while the result show better performance than the traditional cell structure.
