SPARK SPECTROMETER FOR HIGH ENERGY PARTICLES,

After reviewing the difficulties involved in determining the energy of high-energy particles from track curvatures with ionization chambers, movable films, and other methods, the author proposes a spectrometer design consisting of several spark chambers, Fe absorbers, and scintillators. The use and operation of the spectrometer are discussed in extensive detail. Also, variations in configuration are proposed e.g., one in which spark chambers, scintillators, and Fe absorbers are alternated in a stack. In this design the plastic scintillators or the vessels containing the scintillation liquid have a special shape to compensate for the emitted light with respect to the photomultipliers. Author
