Energy resolution andC270900100012 calibration were better than 1 and 2 keV. C270900100013 (VDGT,1USACAL) The 3 MV Pelletron tandem accelerator C270900100014 at the Kellogg Radiation Laboratory at the California C270900100015 Institute of Technology supplied proton beams in the C270900100016 energy range of Ep = 700-2950 keV. Energy resolution C270900100017 was 2 keV, measured using the 27Al(p,gamma)28Si C270900100018 resonance at ER = 991.88+/-0.04 keV. The proton energy C270900100019 was calibrated with this resonance and the C270900100020 28Si(p,gamma)29P resonance at ER = 1380.2+/-0.8 keV C270900100021 to better than l.0 keV. C270900100022 SAMPLE SiO targets were produced by evaporation of SiO2 on to C270900100023 a thick Ta backing. The target thicknesses were C270900100024 50 and 100 mu-g/cm2.
