Proton 2217700100010 beam was continually moved across the target to avoid 2217700100011 overheating and to optimise the yield. Continuous beam2217700100012 currents of up to 70 uAmp were used during 2217700100013 activations. 2217700100014 INC-SOURCE (P-LI7) Metallic layer of natural Li, 1 mg/cm2 thick 2217700100015 and 5 or 6 mm diam, evaporated on a 1.0 mm thick 2217700100016 water-cooled Cu backing. Using 1912 keV protons the 2217700100017 120 deg forward cone of emitted neutrons closely 2217700100018 approximates to a Maxwellian kT = 25 keV shape.

Readings were taken at least every 4 mins 2217700100025 throughout the activations. 2217700100026 METHOD (ACTIV) Sample thickness and diameter and sample/ 2217700100027 monitor foil sequence varied systematically, allowing 2217700100028 uncertainties and corrections to Be studied and 2217700100029 quantified. 2217700100030 (TOF) Before each irradiation the proton energy was 2217700100031 readjusted to produce the required maximum neutron 2217700100032 energy of 106 keV; this best defines the quasi-stellar2217700100033 spectrum at kT = 25 keV. The accelerator was operated 2217700100034 in pulsed mode (1 MHz with 10 ns pulse width) to 2217700100035 enable the neutron energy to be determined using the 2217700100036 TOF technique. 2217700100037 HISTORY (19910411C) S.W. 2217700100038 (19910716A) S.W.
