Calculated performance of a mineral-oil-iron ionization spectrometer

The calculated performances of two slightly different mineral-oil-iron ionization spectrometer designs are presented and compared with experimental data. The particle types considered are electrons, protons, and pions with momenta ranging from 3 to 17.3GeV/c. Many of the factors which contribute to the overall performance of such a spectrometer and which are often omitted in other calculations are included in these calculations. In general, the agreement between the calculated and the experimental results is good. (Auth.)
