| Analysis of Irreversible Heat Emission of Liquid Expansion in a Rapid Cycling Bubble Chamber | ||
| Protvino, 1997.- p.17, figs. 12, tables 2, refs.:12. | ||
The analysis is conducted of the irreversible heat emission during a cycle of the pure liquid expansion of a rapid cycling bubble chamber which can be a significant fraction of the total heat load for a quasi-clean bubble chamber. It is shown that the main origin of the liquid irreversible heat emission consists in oscillations of the expanding liquid and that it is defined by the geometry of the expansion path. The methods of finding the optimal configuration of an expansion path are proposed, which allow one, by diminishing liquid irreversible heat emission, to decrease the total heat load of the working volume of a rapid cycling bubble chamber and thereby to improve its precision.
