摘要:

A survey of the development of the spark chamber from the spark counter is given. An effort has been made to clarify the early history of the device. Some unpublished recent Russian work on spark chambers is summarized. A consistent terminology for the various times relevant to spark chamber operation is suggested.

摘要:

The spark formation time in rare‐gas pulsed spark chambers was investigated as a function of the pulse voltage under various conditions of electrodes, gap lengths, gases, delay times, and clearing fields. An explanation of these formation times was found in terms of a simple process of electron multiplication leading to rapid gas breakdown. Notes on the construction of a thin foil spark chamber and on thyratron pulsers for use with spark chambers are also given.

摘要:

A Lucite wall spark chamber with 0.012‐in. aluminum electrodes, active dimensions 14×14×7 in., has been constructed and tested both with cosmic rays and a particle beam. The gap efficiency is nearly 100% and the time resolution ∼1 &mgr;sec. Construction methods and chamber characteristics are presented.

摘要:

Several spark chambers with a sensitive area of about 6×6 in. have been constructed using 0.005‐in. aluminum plates and 0.25‐in. glass frames as spacers. These were tested with cosmic rays, using neon, argon, and neon‐argon mixtures as the filling gas. A spark gap triggered by scintillation counters was used to apply a high voltage pulse to the plates. Photographs of the sparks produced were analyzed to determine the accuracy with which the track of the cosmic ray could be located. It was found that the electrons nearest the negative clectrode are the ones which 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.
