ACCURACY OF TRACK LOCATION IN SPARK CHAMBERS. PART I
Several spark chambers with a sensitive area of about 6 x 6 in. are constructed using 0.005 in.-thick aluminum plates as electrodes and 0.25-in. glass frames as spacers. These are tested with cosmic rays, using neon, argon, and neonargon mixtures as the filling gas. A spark gap triggered by scintillation counters is used to apply a high voltage pulse to the plates. Photographs of the sparks produced are analyzed to determine the accuracy with which the track of the cosmic ray can be located. It is found that the electrons nearest the negative electrode are the ones that determine the position of the spark. The results give a basis on which to design a spark chamber system to give any desired accuracy of track location and direction. (auth)
