Bubbles grow in size as the chamber expands, until they are large enough to be seen or photographed. Several cameras are mounted around it, allowing a three-dimensional image of an event to be captured. Bubble chambers with resolutions down to a few

The need for a photographic readout rather than three-dimensional electronic data makes it less convenient, especially in experiments which must be reset, repeated and analyzed many times.

The high-energy particles may have path radii too large to be accurately measured in a relatively small chamber, thereby hindering precise estimation of momentum.

Although bubble chambers were very successful in the past, they are of limited use in modern very-high-energy experiments for a variety of reasons:
265:
Bubble chambers are neither large nor massive enough to analyze high-energy collisions, where all products should be contained inside the detector.
