Several high quality electronic units were previously acquired on an individual basis from various manufacturers. As the second research effort in a planned complementary series of papers, the capability of the total array of equipment to accomplish reliable measurements of nuclear radiation was established.To evaluate the performance of the electronic units when assembled into a working coincidence system with associated test and analysis units, positron emitter, was employed with a copper converter as the source of annihilation gamma rays. The annihilation pair gamma-ray energies was precisely 0.511 MeV and the rays were emitted in opposite directions simultaneously. With a range of results that must be attained known, the equipment was arranged, meticulously calibrated and many coincidence counts completed under widely varied conditions. Resolving time and angular resolution were used as the standards for evaluation of the equipment capability. The resolving time was 29.5 nanoseconds while the angular resolution was 14 degrees. These values indicate a very good capability to proceed with many varieties of nuclear radiation research.
