The integrity of the A085600100024 target layers was checked periodically by measuring A085600100025 the Cf-249 and Cm-245 alpha-particle counting rate. A085600100026 DETECTOR (MCPLT) A 4-cm x 12-cm semiconductor detector array A085600100027 with 12 vertical position-sensitive strips surrounded A085600100028 by eight 4-cm x 4-cm side detectors without position A085600100029 sensitivity, forming a box open to the front (beam) A085600100030 side. The position-averaged detection efficiency for A085600100031 full-energy alpha-particles emitted in the decays of A085600100032 implanted nuclei was 87%.
