Abstract
The long-term performance of a set of 20 bubble neutron detectors has been examined over a period of four years. During that time, the detec tors were exposed and reset more than one hundred times. Although depa rtures from the initial detection sensitivity have been noticed in sev eral cases, the detectors indicated a longer lifetime than originally expected. In measurements of the terrestrial background at ambient con ditions, the bubble count rate was found to increase much more rapidly with temperature than in measurements made with a reference Am-Be neu tron source. The use of bubble detectors in cold fusion tests is discu ssed.
