The diameter of focus was 3 S025900100009 mm. Energy of proton was 150 - 250 keV. S025900100010 METHOD (ACTIV) The half-life of N-13 was 10.13 +- 0.1 min. S025900100011 The maximum energy of positron was 1.20 +- 0.005 MeV. S025900100012 After 2 half-lives of irradiation, the high voltage S025900100013 and proton beam were removed. The target ball was S025900100014 turned 180 deg immediately, to face the beta counter. S025900100015 Counting time was 2 half-lives. S025900100016 DETECTOR Beta counter was used to detect the beta positron. S025900100017 The beta counter was covered with lead in the S025900100018 thickness of 52 mm and 12 gamma counters were placed S025900100019 round the beta counter, to reduce the background.
