Part 3/7:
The experiment's design involved applying force to rock samples until failure while diligently monitoring neutron emissions. Two BTI bubble detectors were used for this purpose. These devices, saturated with freon in a gel, create visible bubbles each time a significant number of neutrons pass through them. The construction of the experiment, however, faced limitations due to the equipment; their press could only apply a maximum of 50 tons of force, compared to the 100 tons used in Carman's original studies.
