by the irradiation of Ti with 35 to 150 MeV protons: C043000100008
applications to solar cosmic ray studies C043000100009
FACILITY (CYCLO,1USAHRV) C043000100010
INC-SPECT Incident beam energy and width determined by measuring C043000100011
proton range curve in aluminium. Reductions in energyC043000100012
to desired incident energies were achieved by C043000100013
introduction of polystyrene, and combinations of LexanC043000100014
and lead degraders of accurately known thicknesses. C043000100015
SAMPLE High purity natural titanium foils, 20 mm diameter. C043000100016
