E-740 proportional drift tube tests
The D0 muton detector will consist of large area arrays of proportional drift tubes (PDT's). The beam crossing repetition rate together with the trigger processing time will constrain the maximum drift time to be about one microsecond, corresponding to a drift distance of about 5.0 cm. With such a narrow cell width, it is possible to use rather long cells (up to 6.0 meters) and still keep cell occupancy acceptable. To simplify track reconstruction, space points will be recorded for each track. This will be accomplished using shaped cathode pads to measure the longitudinal coordinate by the ratio of induced charges. In order to have minimal thickness of the PDT arrays, a rectangular cross section has been chosen with an aspect ratio of about 3:1. This choice has necessitated the use of field shaping electrodes to maintain approximately uniform drift velocities. The test cell presented here incorporates cathode pads which have been designed for both longitudinal position measurement and field shaping.
