We have increased by one-half the camera capacity of a Pinex (pinhole-imaging neutron experiment) module originally designed for eight cameras, so that it now contains 12 cameras. The redesigned camera module has been tested and successfully fielded in an underground nuclear test. The key to adding four more cameras was the use of beam splitters in the lines of sight of four of the existing cameras. Half the light going to each of these four existing cameras was thus redirected to one of the new cameras; in this way, the new cameras could be mounted in the module so as not to crowd the eight existing cameras. Full alignment capabilities (tilt and rotation) are maintained for all 12 cameras. This modification to the original design is simple and relatively inexpensive to make, and it increases the sensitivity range and data-acquiring capacity of the camera module by 50%. 4 refs., 7 figs.
