Abstract: A novel detector tube structure (such as for a neutron detection tube) and method of manufacture are described. The novel manufacturing process carries out the electron scrubbing of the detection surface/material after the container enclosure has already been sealed. In this manner, much of the complex manufacturing equipment typically associated with such detection tubes can be eliminated and large numbers of detectors may be manufactured at the same time. The present invention therefore involves a novel detector tube structure and a new method of manufacture for the same.

Abstract: An assembly of components for modifying a battery compartment to allow the use of batteries of a size other than originally designed. The assembly includes a hollow, electrically conductive, cylindrical adaptor, a first end of which is internally threaded for attachment to the existing battery compartment and a second end of which is externally threaded for acceptance of the existing battery compartment cap. The assembly further includes a hollow, electrically insulative, cylindrical insert. The adaptor and insert each include conductive electrical elements to connect a new configuration battery positioned within the insert to the existing battery compartment and compartment cap contacts. The adaptor and insert are coaxially aligned and loosely attached together in a manner that allows free rotational movement between them about a common central axis while retaining the adaptor and insert in close association.
