F020200100005 AUTHOR (B.Fabre,H.Yamada,B.M.Spicer) F020200100006 INSTITUTE (3AULAML) F020200100007 REFERENCE (J,NP/A,572,349,1994) F020200100008 FACILITY (VDG,3AULAML) 5U Pelletron F020200100009 INC-SOURCE Mono-energetic proton beam. F020200100010 INC-SPECT Energy spread of proton beam entering the beam line is F020200100011 less than 1 keV. Magnetic quadrupole lenses were used F020200100012 to focus the beam onto the target. Beam spot sizes wereF020200100013 less than 1 mm diameter. F020200100014 SAMPLE 40 mu-g/cm2 self-supporting foil of 99.99% pure 12C F020200100015 separated isotope target was used. Target ladder could F020200100016 hold two carbon target. Target was placed at 45 degreesF020200100017 to the beam direction to provide good transmission of F020200100018 back-scattered protons and protons through the target. F020200100019 DETECTOR (SCIN) Thin annular NE102A plastic scintillator was F020200100020 mounted onto a Perspex light guide and a photo- F020200100021 multiplier arrangement. F020200100022 (SIBAR) Surface barrier (S.B.) detector was placed at F020200100023 90 degrees to the beam for normalization of the charge F020200100024 collection system and for measuring the proton back- F020200100025 scattering yield. F020200100026 METHOD (BCINT) F020200100027 Gold target was used for calibration purposes. F020200100028 Carbon build-up on the target was monitored by F020200100029 regularly measuring the proton back-scattering yield.
