Abstract We have studied the performance of limited streamer drift tubes made of conductive plastic. Spatial resolution and rate capability obtained are 100–150 μm and 2–3 kHz/cm, respectively.
A soundproof engine-operated machine or generator includes a floor having first and second air discharge hole, wall members cooperating with the floor in defining a container, at least one wall… (More)
Abstract We constructed and tested a prototype gas sampling electromagnetic calorimeter of the Pb-proportional tube sandwich type. The calorimeter uses conductive plastic tubes and cathode pad… (More)
Abstract The performance of cathode readout on the limited streamer drift tubes with conductive plastic wall was studied. Cathode strips were placed on the outside of tubes in parallel and… (More)
Abstract A prototype of an automated monitoring and calibrating system of gas gain and electron drift velocity for the end cap detectors in TOPAZ  is constructed. Systematic data under various… (More)
A prototype of gas sampling electromagnetic calorimeter with conductive plastic tubes was studied under practical conditions. An energy resolution of σEE = 20.4(E(GeV))−12 (%) was obtained in the… (More)
