THE DEPENDENCE OF THE BUBBLE DENSITY FOR AN IONIZING PARTICLE ON THE TEMPERATURE AND PRESSURE IN A BUBBLE CHAMBER. PART II. COMPARISON BETWEEN THEORIES AND EXPERIMENTAL RESULTS
The bubble nucleating mechanism in the bubble chamber is discussed in view of some of the existing experimental evidence for a description of the process, either by the occurrence of free electrical charges on the bubbles as required by the electrostatic theory or a localized heating of small regions in the liquid as given by the thermal theory. Calculations of the temperature dependence of operating conditions to be expected when either theory is correct were made with the use of a somewhat simplified model. The calculated temperature dependences were also compared with those experimentally obtained by measurements of the bubble density as a function of pressure drop and temperature in the liquid for electrons of 18 Mev mean energy. The liquids used are propane, Freon-12, and sulphurhexafluoride. The experimental results for these liquids are in very good agreement with the behavior of the bubble chamber as estimated from the thermal theory. (auth)
